SADISOPSG/15


Agenda Item 4: Operation of the SADIS 4.1: SADIS management report

4.1.1 The group noted that, in accordance with Conclusion 7/1, the SADIS Provider State had prepared a management report which had been placed on the ICAO SADISOPSG website more than two months prior to this meeting. The group expressed its compliments to the SADIS Provider State for providing a detailed and informative report on the web. The group was pleased to note that the complete management report included statistics on the non-scheduled OPMET messages received at the SADIS uplink station (as called for by Conclusion 8/8) and a list of aerodromes, corresponding to Annex 1 to the SADIS User Guide, whose OPMET data had not been received at the SADIS uplink station (as called for by Conclusion 8/7 b)).

4.1.2 A concise summary of the management report highlighting the main issues and developments that had taken place between March 2009 and February 2010 was noted by the group. No issues requiring particular attention by the SADIS Provider State were singled out.

SADISOPSG/15


Agenda Item 4: Operation of the SADIS 4.2: SADIS focal points

4.2.1 The group recalled that the PIRGs had endorsed the SADISOPSG/4 draft conclusion concerning the nomination by SADIS user States of SADIS operational focal points; such a list was considered to provide useful contacts for the SADIS Provider State and the ICAO regional offices to resolve issues regarding, inter alia, missing or incorrectly formatted messages and headers. The current list of focal points, updated by the Secretary based on a consultation with all SADIS user States in response to Conclusion 14/2, is given in Appendix B to this report.

4.2.2 In view of the importance of the list of SADIS focal points, it was agreed that ICAO should consult all the SADIS user States to ensure that the information was current. The group reviewed the list of SADIS operational focal points and formulated the following conclusion:

Conclusion 15/2 — Update of the list of SADIS focal points That, the Secretariat consult with all the SADIS user States in order to update the list of the SADIS focal points in time for the dispatch of the SADIS efficacy questionnaire (20 December 2010).

SADISOPSG/15


Agenda Item 4: Operation of the SADIS 4.3: Operational efficacy of the SADIS

Results of the consultation

4.3.1 It was recalled that, in accordance with SADISOPSG Conclusions 1/4 and 2/3, the group had agreed to provide an annual statement of SADIS operational efficacy to the SADIS Cost Recovery Administrative Group (SCRAG), based on the views of States/users on the subject, solicited by ICAO prior to each meeting. The Secretariat had circulated the questionnaire to all States under the SADIS “footprint” and to the Agence pour la Sécurité de la Navigation Aérienne en Afrique et à Madagascar (ASECNA). To improve the response rate of the annual SADIS questionnaire, the questionnaire had been placed on the SADISOPSG website in an interactive format and sent, in addition to users and States, to the SADIS focal points, in response to Conclusion 6/2. The group was pleased to note that the number of replies had substantially increased from the last few years, i.e. 57 compared to 44 and 48, in 2009 and 2008, respectively.

4.3.2 A tabulated summary, including specific comments, had been compiled by the Secretariat based on the completed questionnaires returned by States. In accordance with Decision 9/3, the summary had been subsequently forwarded to the SADIS Provider State which had prepared, on behalf of the SADISOPSG Operational Efficacy Assessment Team, a report on the operational efficacy, as called for by Decision 4/4. The group was pleased to note that all the issues raised by SADIS users had been addressed by the SADIS Provider State in this report.

4.3.3 An analysis of the completed questionnaires indicated the following (the statistics for year 2008-2009 in brackets, in accordance with Conclusion 6/3; indicated in percentage, out of a total of 57 and 44 replies received from States, respectively, rounded to the nearest 5 per cent):

a) Concerning the SADIS 2G satellite broadcast:

1) 10 (10) per cent experienced signal quality problems;

2) 90 (85) per cent reported good availability of WAFS bulletins in the GRIB code;

3) 90 (85) per cent reported good availability of WAFS bulletins in the BUFR code; and

4) 95 (85) per cent reported good availability of OPMET messages; and

b) concerning the reliability of VSAT receiving equipment:

1) 95 (not available) per cent considered it to be “good”; and

2) 10 (10) per cent of receivers had to be returned for repairs; and

c) concerning the SADIS FTP service (statistics not available for 2008/2009):

1) 10 per cent experienced problems in the service quality;

SADISOPSG/15


2) 90 per cent reported good availability of WAFS bulletins in the GRIB code;

3) 95 per cent reported good availability of WAFS bulletins in the BUFR code;

4) 85 per cent reported good availability of OPMET messages; and

5) 95 per cent considered it to be “good”; and

d) concerning the visualization of WAFS SIGWX forecasts:

1) 80 (70) per cent produced compliant WAFS charts from BUFR bulletins; and

2) 60 (60) per cent used WAFS forecasts in the PNG format; and

e) concerning the service desk and administrative messages:

1) 75 (70) per cent did not use the 24-hour service desk; and

2) 5 (5) per cent considered that the administrative messages were not adequate.

4.3.4 It was agreed that the figures were comparable to, or better than, those received last year. The group was particularly pleased to single out two positive developments over the last year:

a) increased capacity of producing compliant SIGWX charts from the BUFR-coded WAFS forecasts; and

a) improved availability of OPMET messages via the SADIS 2G.

4.3.5 Based on the responses received, the group reiterated its satisfaction with the quality of SADIS service considered good by a clear majority of users and with the fact that the number of States with serious difficulties with their SADIS VSAT had remained small.

Format of the questionnaire

4.3.6 The group recalled that the questionnaire on SADIS efficacy had been developed by the Secretariat, in consultation with the Chairman of the SADISOPSG and the SADIS Provider State, and thoroughly revised at the SADISOPSG/14 Meeting (Decision 14/3 refers) to improve its clarity and to add a section related to the SADIS FTP service which was being increasingly used. The group agreed that, at this stage, there was no need to undertake any further revisions. However, in view of the full implementation of SADIS 2G (except for two States which intended to continue to use the SADIS FTP as their primary source of information), the group agreed that the question related to its implementation should be eliminated. The group formulated the following decision:

SADISOPSG/15


Decision 15/3 — SADIS efficacy questionnaire

That, the questionnaire used in future consultations with States/users on the operational efficacy of the SADIS broadcast and SADIS FTP service be unchanged, except for the elimination of the question related to the implementation of the SADIS 2G VSAT.

Annual statement

4.3.7 The group, including IATA, agreed that, in the light of comments received, the SADIS broadcast and SADIS FTP service continued to meet the operational requirements during the period under review and to formulated the following conclusion:

Conclusion 15/4 — Annual statement of operational

efficacy of SADIS 2009/2010 That, the Chairman of the SADISOPSG be invited to inform the Chairman of the SCRAG that, during the period 2009/2010, the SADIS continued to meet the operational requirements.

SADISOPSG/15


Agenda Item 4: Operation of the SADIS 4.4: SADIS inventory

4.4.1 The latest inventory which formed the basis for SADIS cost recovery purposes had been developed by the SADISOPSG/14 Meeting and used by SCRAG at its tenth meeting (SCRAG/10) held in Paris in November 2009. The inventory has since been updated by the SADIS Provider State in two respects:

a) staff costs were expressed in terms of staff-days, instead of percentages of staff, in accordance with instructions given by the SCRAG; and

b) the hardware refresh undertaken (in response to Conclusion 14/23) had been included.

4.4.2 The group reviewed the inventory including the draft amendments and formulated the following conclusion:

Conclusion 15/5 — SADIS Inventory 2010-2011 That, the Chairman of the SADISOPSG be invited to forward the updated SADIS inventory given in Appendix C to this report to the Chairman of SCRAG.

SADISOPSG/15


Agenda Item 4: Operation of the SADIS 4.5: SADIS implementation

4.5.1 The group was pleased to note that the number of States and users had increased during 2009/2010 with 102 (95 in 2008/2009) Contracting States relying on a total of 121 (104 in 2008/2009) SADIS 2G VSAT receivers and 131 (46 in 2008/2009) FTP servers. A further 8 (12 in 2008/2009) Contracting States had received authorized access, some of which were in the process of installing SADIS VSAT receivers or FTP servers. The group highlighted the fact that, during the past year, the number of SADIS FTP users had almost tripled, similar to the previous year.

Agenda Item 5: Content of the SADIS broadcast 5.1: OPMET information

METAR, SPECI and TAF

General considerations concerning the requirements and actual content of the SADIS broadcast

5.1.1 The group recalled that the requirements by States and users for METAR, SPECI and TAF to be broadcast on the SADIS were given in Annex 1 to the SADIS User Guide (SUG) which was extracted from a global OPMET database maintained by the ICAO Secretariat. Annex 1 included OPMET information from both AOP (i.e. aerodromes included in the aerodrome operational planning (AOP) tables of the regional air navigation plans) and non-AOP aerodromes.

5.1.2 In response to Conclusion 8/6, OPMET information from all the AOP aerodromes was included in Annex 1. All AOP aerodromes issued METAR and SPECI, as a minimum (with few exceptions in the EUR Region), while the requirements for TAF were subject to formal regional air navigation (RAN) agreement which was reflected in the Tables MET 1A of all the facilities and services implementation documents (FASID). The group recalled that, since February 2008, similar to Annex 1, all FASID Tables MET 1A were extracted from the global OPMET database thus ensuring the consistency of information between the FASID Tables MET 1A and Annex 1. This arrangement also implied that Annex 1 now reflected, at all times, the formal requirements displayed in FASID Tables MET 1A. Furthermore, the group had agreed that any proposals for amendments related to OPMET data from AOP aerodromes should be addressed directly to the ICAO Regional Office concerned (Decision 13/8 refers). This approach eliminated the need for a lengthy procedure (i.e. formulation by the SADISOPSG of draft conclusions for endorsement by the PIRGs concerned) and substantially expedited the implementation of new requirements.

5.1.3 With regard to non-AOP aerodromes, the group was aware of the fact that OPMET information from these aerodromes could be included in Annex 1 only if the State concerned had no objection to its distribution on the SADIS and with the understanding that States did not have any obligation of providing such data for non-international aerodromes. OPMET requirements from these aerodromes may be amended by the group annually, subject to an agreement by the State concerned.

5.1.4 It was further recalled that the actual OPMET information that was currently broadcast on SADIS was indicated in Annex 2 (listing the aerodromes included in the bulletins) and Annex 3 (listing the bulletin headers). These annexes were updated bi-annually, with the assistance of the EUR Bulletin Management Group (BMG).

Non-implementation of requirements for OPMET data by States

5.1.5 The variability of reception of OPMET data from some aerodromes had been cause for adverse comments in the past. However, where such comments concerned aerodromes not listed as a requirement in Annex 1, the SADIS Provider State was unable to pursue missing data from these aerodromes. Non-availability of OPMET data from aerodromes listed in Annex 1 was a different matter and, when notified by users, had been systematically brought to the attention of the States concerned by the appropriate ICAO regional office which had kept on monitoring such deficiencies until their

SADISOPSG/15


resolution. The group concurred that such a real-time approach had turned out to be efficient and had led, in most cases, to the timely resolution of the deficiencies identified.

Draft amendments to Annex 1 to the SUG

5.1.6 The group reviewed the OPMET data required from non-AOP aerodromes based on a proposal made by the International Air Transport Association (IATA). It was noted that the proposal attempted to render the requirements in line with OPMET data that was actually made available by States. In this regard, the group concurred that any proposed deletions could be undertaken by the Secretariat without need for consulting the States concerned while any proposed additions would have to be endorsed by them. It was noted that only those aerodromes with location indicators included in the Location Indicators (Doc 7910) could be included in Annex 1 to the SUG. The group reviewed the proposal, endorsed the proposed changes with the understanding that there would be no substantial cost impacts due to the limited number of aerodromes that were expected to be included and formulated the following conclusion:

Conclusion 15/6 — Revision of Annex 1 concerning OPMET information from non-AOP aerodromes

That, ICAO

a) seek agreement from the States concerned to provide OPMET information from non-AOP aerodromes as depicted in Appendix D to this Report;

b) amend Annex 1 to the SADIS User Guide accordingly by 31 December 2010; and

c) report back to the SADISOPSG/16 Meeting the number of aerodromes actually added in Annex 1, as a result of the consultation with the States concerned.

Note 1. - Only non-AOP aerodromes for which location indicators are listed in Doc 7910, Location Indicators will be considered in this context; and

Note 2. - States have the prerogative of not providing any OPMET data from non-AOP aerodromes, if not considered appropriate or desirable by them.

Harmonization of the OPMET content in SADIS and ISCS

5.1.7 Since Annex 1 reflected the global requirements by users (e.g. airlines) and States for OPMET data, the group considered that they should be applicable for both the SADIS and ISCS broadcast. Their validity for the ISCS broadcast was confirmed by the fact that Annex 1 to the SUG had been included, without any changes, in the ISCS User Guide. The group was pleased to learn as part of the report by the SADISOPSG Gateway Development Team under Agenda Item 6.1 that the overall

SADISOPSG/15


harmonization between the SADIS and ISCS broadcasts had been progressed near to completion. It may be noted that outstanding issues would be addressed under Agenda Item 6.1.

Non-scheduled OPMET information

5.1.8 In view of the importance of non-scheduled OPMET information for aviation (e.g. SIGMET, AIRMET, tropical cyclone and volcanic ash advisories), the group recalled that it had agreed that the reception of these messages should be monitored by the SADIS Provider State, which should compile annual statistics showing the number of all types of non-scheduled OPMET information received at the SADIS uplink station and present these results to the SADISOPSG as part of the annual management report (Conclusion 8/8 refers). The group was pleased to note that this information which may be considered to be highly relevant had been included in the management report.

5.1.9 The group noted that the fourth meeting of the International Airways Volcano Watch Operations Group (IAVWOPSG/4) had formulated Conclusion 4/28 b) requesting volcanic ash advisory centre (VAAC) London to transmit the Nuclear Emergency Message received from the International Atomic Energy Agency (IAEA) through the ICAO aeronautical fixed service (AFS). Since SADIS formed part of the AFS, the group agreed that the inclusion of the Nuclear Emergency Message therein would foster its availability to aviation users and formulated the following conclusion:

Conclusion 15/7 — Inclusion of Nuclear Emergency Message in SADIS

That, the SADIS Provider State include the Nuclear Emergency Message received from the International Atomic Energy Agency (IAEA) in the SADIS broadcast and SADIS FTP Service, in time for the applicability of Amendment 75 to Annex 3.

Note. - In view of harmonization between SADIS and ISCS, it may be expected that the Nuclear Emergency Message be also included, in due course, in ISCS.

SADISOPSG/15


Agenda Item 5: Content of the SADIS broadcast 5.2: WAFS forecasts

5.2.1 The group recalled that the list of the world area forecast system (WAFS) forecasts disseminated on SADIS was included in Annex 4 to the SUG which had been updated last time in 2008 to include the new GRIB 2-coded WAFS forecasts. This update had been subsequently endorsed by the SADISOPSG/14 Meeting. The group noted that since that meeting, no amendments to the list of WAFS forecasts broadcast on SADIS contained in Annex 4 had been made, and therefore concurred that there was no need to formulate any decisions in this regard.

SADISOPSG/15


Agenda Item 6: Development of the SADIS 6.1: Report of the SADISOPSG Gateway Development Team

6.1.1 The group recalled that the SADIS gateway function had been developed in response to the European Air Navigation Planning Group (EANPG) Conclusion 38/33 and that, at subsequent meetings, it had developed a set of high-level technical requirements, including the real-time monitoring. It had also finalized the SADIS Gateway Operations Handbook which was available on the SADISOPSG website, in accordance with Conclusion 8/15. The system had been fully operational since 2003.

6.1.2 The group took note of the report by the Rapporteur of the SADISOPSG Gateway Development Team related to the progress made since the SADISOPSG/14 Meeting. In this report, the group’s attention was drawn to three specific issues:

a) SIGMET validation;

b) harmonization of the OPMET content between the SADIS broadcast, SADIS FTP service and ISCS broadcast; and

c) removal of the TAF auto-correction function.

Validation of SIGMET at the SADIS gateway

6.1.3 Concerning the validation of SIGMET, the group recalled that SADISOPSG Conclusion 13/12 had urged States to comply with the provisions of Annex 3 — Meteorological Service for International Air Navigation provisions as far as the format of SIGMET bulletins was concerned. The implementation of the correct format had been considered essential by the group since the low level of implementation had rendered the real-time monitoring of SIGMET at the SADIS gateway impracticable. The results in 2009 had been encouraging since compliance had increased significantly to a value of 64.4 per cent from 38.8 per cent the previous year and there was considerable optimism that the 80 per cent threshold considered necessary for the implementation of SIGMET validation would be achieved in 2010.

6.1.4 The group was disappointed to learn that the results of the 14-day analysis undertaken in early 2010 had shown no improvement on the compliance in 2009; it had remained insufficient to trigger the automatic validation at the SADIS gateway. The results further indicated that particular problems with compliance persisted in Canada, India and the United States. To address this safety issue, the group agreed that the foregoing States should be reminded of the importance of the correct format of SIGMET and formulated the following conclusion:

Conclusion 15/8 — Implementation of the correct format of SIGMET

That, in order to ensure the safety of aircraft operations, the Secretariat urge Canada, India and the United States to implement, as a matter of urgency, the correct format of SIGMET as contained in Annex 3.

SADISOPSG/15


Harmonization of the OPMET content between SADIS and ISCS

6.1.5 With regard to the harmonization of the operational meteorological (OPMET content between the SADIS and international satellite communications system (ISCS), the group recalled that substantial progress had been made last year. It was pleased to note that further steps were expected with the introduction of revised bulletins by the ISCS Provider State, which would render the set of bulletins consistent on both systems.

6.1.6 In spite of the progress made, the group considered that, based on the monitoring of the SADIS broadcast over a period of 9 weeks by IATA, the harmonization efforts should continue to further align the content of the ISCS and SADIS broadcasts. In view of the foregoing, the group formulated the following conclusion:

Conclusion 15/9 — Harmonization of the OPMET content of the SADIS and ISCS broadcasts

That, the SADIS Provider State, in coordination with the ISCS Provider State, continue its efforts to harmonize the required OPMET content of the SADIS and ISCS broadcasts.

Note 1. - The aim is to reach a 95 per cent availability of OPMET data on SADIS and ISCS broadcasts as soon as possible, but not later than the SADISOPG/16 meeting;

Note 2. – Required OPMET content is listed in Annex 1 to the SUG; and

Note 3. – Bi-annual monitoring comparing the contents of the two broadcasts will be undertaken by the EUR BMG.

Removal of the TAF auto-correction function

6.1.7 Concerning the TAF auto-correction, the group recalled that it had been removed prior to the SADISOPSG/14 Meeting due to its incompatibility with the new TAF code form introduced by Amendment 74. The group was pleased to note that the corresponding updates to the SADIS Gateway Handbook as called for by Conclusion 14/14 had been published in November 2009 as part of the fourth edition of the document.

SADISOPSG/15


Agenda Item 6: Development of the SADIS 6.2: Report of the SADISOPSG Strategic Assessment Team

6.2.1 Based on a report provided by the SADISOPSG Strategic Assessment Team, the group reviewed the format and content of the strategic assessment tables. It was noted that the current figures for 2010 had been obtained from an analysis of the OPMET data promulgated to SADIS via the SADIS Gateway and that the draft figures for 2011-2013 had been prepared by the SADIS Provider State using the current figures as a base line. This would ensure that projected figures were consistent with the current OPMET data distributed on the SADIS. On completion of the review of the tables, the group requested the Secretariat to forward the tables to the MET sub-groups (SGs) of the planning and implementation regional groups (PIRGs) concerned in 2010, in view of forming the basis for the next regional update of future SADIS requirements, including the figures for the year 2014. In this regard, the group formulated the following conclusion:

Conclusion 15/10 – SADIS Strategic Assessment Tables

That,

a) the SADIS Provider State take note of the completed SADIS Strategic Assessment Tables, provided in Appendix E to this report, to form the basis for the future development of the SADIS; and

b) the Secretariat forward the SADIS Strategic Assessment Tables to the subgroups of the PIRGs concerned for update in respect of future requirements.

Note 1. - Any major changes to the SADIS will be subject to draft conclusions, to be formulated by the SADISOPSG, to be endorsed by the relevant PIRGs, and to be noted, as necessary, by the Commission or Council; and

Note 2. - Completed SADIS Strategic Assessment Tables are provided by ICAO Regional Offices to the SADISOPSG following consideration at appropriate sub-group meetings of the PIRGs concerned.

6.2.2 With regard to the format of the strategic assessment tables, the group agreed that the current format fully reflected the data originated outside the world area forecast centres (WAFCs) and promulgated on the SADIS; therefore it was agreed that there was no need to amend the current format.

6.2.3 The group considered whether separate tables related to data volumes of WAFS forecasts disseminated on the SADIS should be included. It was noted that the strategic assessment tables had been initially introduced to allow the MET SGs of the PIRGs to express the expected future regional requirements for OPMET-message dissemination on the SADIS. The group agreed that the estimated data volumes for WAFS forecasts in the GRIB1, GRIB2, PNG and BUFR code forms were global in nature and that no input from the MET SGs could be expected in this regard. Therefore, it was concurred that there was no need to refer the new tables for formal consideration by the MET SGs; they should simply be provided for information and be dealt with separately from the regional strategic assessment tables. The group formulated the following conclusion:

SADISOPSG/15


Conclusion 15/11 — SADIS Strategic Assessment Tables – inclusion of expected GRIB1, GRIB2, PNG and BUFR data volumes

That, the SADIS Strategic Assessment Team, in consultation with the SADIS Provider State, provide estimates of future data volumes related to WAFS forecasts in the GRIB1, GRIB2, PNG and BUFR code forms, as an attachment to the SADIS Strategic Assessment Tables.

Note. - These data volumes are provided to the MET SGs for information purposes only.

SADISOPSG/15


Agenda Item 6: Development of the SADIS 6.3: Report of the SADISOPSG Technical Developments Team

6.3.1 The group recalled that the SADISOPSG Technical Developments Team was expected to monitor, report on and propose action on technological developments having an impact on SADIS. Over the last 12 months, the major technical developments addressed by this team were related to:

a) future utilization of the SADIS satellite bandwidth (Conclusion 14/25 refers);

b) transmission of GRIB2 data on the SADIS 2G (Conclusion 14/16 refers); and

a) SADIS 2G uplink protocols (Conclusion 14/24 refers).

Future utilization of the SADIS satellite bandwidth

6.3.2 The group recalled that the SADISOPSG/14 Meeting had formulated Conclusion 14/25 which had called for the SADIS Provider State, in coordination with the SADISOPSG Technical Developments Team, to review SADIS satellite bandwidth allocation taking into account the expected changes in the WAFS forecasts (e.g. dissemination of GRIB2-coded WAFS forecasts) and report back the findings thereof to the SADISOPSG/15 Meeting. It was understood that the need for any end-user hardware changes was to be considered in this context.

6.3.3 The group recalled that the Second Generation Satellite Distribution System (SADIS 2G) made use of dedicated satellite uplink/downlink capacity. Furthermore, the now retired First Generation SADIS (SADIS 1G), whilst no longer requiring uplink/downlink capacities had, nonetheless, had its operational capacity retained with the view that it may be necessary to make this now “spare” capacity available to SADIS 2G in light of expected developments with regard to the provision of WAFS GRIB2 forecasts over the SADIS 2G system.

6.3.4 The group noted the detailed review related to the SADIS satellite bandwidth allocation taking into account the expected changes in the WAFS forecasts prepared by the SADIS Technical Developments Team, in coordination with the SADIS Provider State. The group endorsed the following conclusions drawn from this review:

a) with careful management, GRIB1 and GRIB2 data volumes could be managed such that the current SADIS 2G bandwidth allowances were sufficient and did not need to be increased;

b) during the periods of GRIB1 and GRIB2 transmissions where sustained rates of transfer of the order 60 kbps were made for some tens of minutes, it had been confirmed that there were no adverse delays to OPMET data; and

c) regarding the future XML schemas to be used for all OPMET exchanges, it was considered that it was not possible to make informed decisions in this regard due to the lack of detailed information.

SADISOPSG/15


6.3.5 Based on the foregoing, the group agreed that the existing SADIS 2G data transfer rate of 64 kbps was sufficient for the foreseen needs of the service, including the introduction of GRIB2 transmissions, subject to the introduction of GRIB2 data being suitably managed and prioritized against GRIB1 data. Accordingly, the group formulated the following conclusion:

Conclusion 15/12— SADIS 2G future bandwidth requirements

That, the SADIS Provider State

a) relinquish the currently retained SADIS 1G satellite bandwidth at the end of the current contract (31 December 2010) to save some £30 000 per annum from the SADIS cost base;

b) inform the Chairman of the SCRAG on the cessation of that part of the contract; and

c) prepare, in time for the SADISOPSG/16 Meeting, an implementation plan, in coordination with the SADIS Technical Developments Team, concerning the GRIB2 and GRIB1 data sets over the SADIS 2G broadcast such that the two datasets are not transmitted at the same time.

Note 1. - The existing SADIS 2G satellite bandwidth and transfer speed of 64kbps will be retained until such time as directed otherwise by the SADISOPSG;

Note 2. - The implementation plan will include a prioritization of the GRIB1 versus GRIB2 datasets; and

Note 3. - The SADIS Provider State, assisted by the Secretariat and the SADIS Technical Developments Team, will closely monitor the progress of the implementation of OPMET data in table-driven codes (e.g. XML) and report back to the group in due course.

Transmission of GRIB2 data over satellite

6.3.6 The group recalled that the SADISOPSG/14 Meeting had formulated Conclusion 14/16 calling for the SADIS Provider State, in coordination with the SADISOPSG Technical Developments Team, to complete the trial of compressed GRIB2 coded data by 30 September 2009 and present proposals, for endorsement by the SADISOPSG/15 Meeting, for further steps in view of introducing the transmission of GRIB2 coded data on the SADIS 2G broadcast as an operational procedure. It had been noted that the inclusion of GRIB2 forecasts for CB clouds, icing and turbulence would be subject to endorsement by the World Area Forecast System Operations Group (WAFSOPSG) and that the decoding and decompression software would be made available at no cost to SADIS users. Furthermore, the group had understood that the inclusion of the GRIB2 data in the SADIS 2G broadcast was to be performed in coordination with the ISCS Provider State.

SADISOPSG/15


6.3.7 Following on from trials of transmission of uncompressed GRIB2 over the SADIS 2G where it had been determined that a data volume of around 50 MB took approximately 1hr 55min to transmit (compared to around 10 MB and approximately 30 min for GRIB1 over the SADIS), completion of trials to determine the data volumes and time of transmission for compressed versions of the GRIB2 data were undertaken.

6.3.8 The group noted that the results of the tests undertaken in September 2009 and February 2010 involving compressed bulletins indicated that the transmission over the SADIS 2G of the:

a) complete dataset (i.e. 1078 bulletins including forecasts of cumulonimbus (CB) clouds, icing and turbulence) compressed to about 22 MB, took approximately 45 to 50 minutes; and

b) reduced dataset (i.e. 671 bulletins excluding forecasts of CB clouds, icing and turbulence) compressed to about 16 MB took approximately 35 minutes.

6.3.9 It was noted that the results of these tests had indicated that the datasets were successfully received and decompressed. Furthermore, the comparison of NATS TAF/METAR bulletin transmission logs against the reception logs provided by KNMI and MeteoSwiss in February 2010 had shown that the delays were between 1 to 5 seconds, demonstrating that there was no significant, negative impact on TAF/METAR reception.

6.3.10 Whilst these tests demonstrated that GRIB2 WAFS data could be successfully transmitted, decompressed and visualized when broadcast via the SADIS 2G, the group concurred that there were additional considerations that needed to be taken into account, i.e. avoiding conflicts with the transmission of OPMET messages and WAFS forecasts in the GRIB1 code form, and considering the operational acceptability of forecasts for CB clouds, icing and turbulence to the aviation users. In this regard, the group concurred that the transmission of the WAFS forecasts in the GRIB2 code form over the SADIS 2G be:

a) 1 hour later than that of the WAFS forecasts in the GRIB1 code form to avoid any negative impact on the timeliness of the OPMET messages and WAFS forecasts in the GRIB1 code form; and

b) initially limited to be the dataset excluding the new forecasts of CB clouds, icing and turbulence, with the understanding that the new forecasts be included as soon as they were considered operational by the WAFSOPSG.

It was noted that these arrangements would also be applicable under back-up. Based on the foregoing, the group formulated the following conclusions:

SADISOPSG/15


Conclusion 15/13 – Further tests over SADIS 2G of GRIB2 data to enable workstation vendors to develop and test their systems

That, to enable workstation vendors to develop and test their systems, the SADIS Provider State, with assistance of the SADIS Technical Developments Team, carry out further test/development transmissions of GRIB2 WAFS data before the operational implementation of the broadcast.

Note 1. - Transmission times should be such that they do not conflict with GRIB1 transmissions; and

Note 2. - SADIS users will be provided with a schedule containing the exact dates and times of transmission through SADIS administrative messages; and

Note 3. – Test transmissions will be via the fourth SADIS 2G channel, available to vendors only.

Conclusion 15/14 – Operational transmission of GRIB2 WAFS forecasts over the SADIS 2G broadcast

That, the SADIS Provider State, in coordination with the ISCS Provider State, implement the transmission of GRIB2 WAFS forecasts with effect from 1200 UTC data (transmitted 1600 to 1655 UTC) on 18 November 2010, subject to the following conditions:

a) transmission of GRIB2 WAFS forecasts will be 1 hour after the transmission of GRIB1 WAFS forecasts; and

b) forecasts for CB clouds, icing and turbulence in the GRIB 2 code form that are currently considered “trial forecasts” will not be transmitted until endorsed by the WAFSOPSG.

Note 1. - Transmission times for GRIB2 WAFS forecasts will initially be 0400-0455 UTC for DT 0000; 1000-1055 UTC for DT 0600; 1600-1655 UTC for DT 1200; and 2200-2255 UTC for DT 1800, and the SADIS users will be informed accordingly through administrative messages;

Note 2. – The users of GRIB1 data will not be affected by

the introduction of the GRIB2 WAFS forecasts; and Note 3. – User States are advised to contact their vendors

for possible system upgrades.

SADISOPSG/15


SADIS 2G Uplink protocols

6.3.11 The group recalled that the SADIOPSG/14 Meeting had tasked the SADIS Provider State to determine what transfer protocol (i.e. X25 protocol versus Internet Protocol (IP)) between Exeter and Whitehill was the most efficient to use, and whether or not it was justifiable to increase the bandwidth of the two fixed links between Exeter and Whitehill to 128 kbps each from their current 64 kbps each (Conclusion 14/24 refers).

6.3.12 The group recalled that the current arrangement was that data was transmitted from the Met Office FROST Message Switch to the VadEDGE 4200 Routers using IP. The VadEDGE routers at Exeter converted the data to X25 before onward transmission to the MegaPAC-V-IX. The MegaPAC-V-IX converted the data a third time to the VSAT protocol. The group noted that the SADIS Technical Developments Team had assessed the possibility of using the IP instead of the X25 Protocol in the Exeter to Whitehill link, thus saving one conversion and also complying with a general desire to move away from X25 within the SADIS Provider State’s infrastructure.

6.3.13 The group noted that the SADIS Technical Developments Team had considered, in coordination with the SADIS Provider States, the advantages and disadvantages of X25 against IP and the justification to increase bandwidth to 128 kbps. The group endorsed the findings of the detailed analysis which indicated that:

a) it would be disadvantageous to replace the existing X25 Protocol with the IP between Exeter and Whitehill due to the lack of error correction and increased communication overheads related to the use of IP. It was considered that a change of protocol from X25 to IP would only be viable with a complete redesign of the system; and

b) with regard to the transmission rate of the links between Exeter and Whitehill, the foreseen needs of the SADIS 2G could be met with the current infrastructure (i.e. 64 kbps transmission rates), and there was no need to increase the transmission rate (bandwidth) of the satellite broadcast, nor the capacity of the physical lines.

6.3.14 In order to formally endorse the above findings, the group formulated the following decisions:

Decision 15/15 — Retention of the X25 Protocol for the Exeter to Whitehill segment of the SADIS 2G

That, the SADIS Provider State continue to use the X25 Protocol for the Exeter to Whitehill segment of the SADIS 2G satellite broadcast.

Decision 15/16 — Retention of existing capacity of fixed lines

between Exeter and Whitehill That, the SADIS Provider State retain the existing capacity of 64 kbps for each of the fixed lines between Exeter and Whitehill.

SADISOPSG/15


Agenda Item 6: Development of the SADIS 6.4: SADIS Internet-based FTP Service

6.4.1 The group recalled that the SADIS FTP service had been in operation for a number of years and had consistently seen the number of users accessing the service grow year-upon-year, as well as seen a growth in the number of products being accessed by those users. Furthermore, it was expected that during the next few years it was likely that the downloading of WAFS forecasts in the GRIB2 code form would introduce a sharp rise in downloaded products.

Implementation of SADIS FTP

6.4.2 The group recalled that it had formulated Conclusion 14/19 calling for the SADIS Provider State to increase the SADIS FTP Internet bandwidth allocation to 4 Mbps bursting to 8 Mbps between server and Internet service provider (with individual client connections guaranteed at 64 kbps, bursting to 512 kbps), in time for the SADISOPSG/15 Meeting. It was noted that the bandwidth allocation had been increased accordingly on 31 January 2010.

Development of “Secure SADIS FTP service”

6.4.3 It was recalled that the group had formulated Conclusion 14/18 calling for the SADIS Provider State, in coordination with the SADIS Technical Developments Team, to proceed with the development of a SADIS FTP Secure service (“Phase 2”) and provide a progress report on the status of the implementation of Phase 2 to the SADISOPSG/15 Meeting. It had been further noted that the Phase 2 was expected to be operational by November 2010 and would run in parallel with the existing SADIS FTP Enhanced service (“Phase 1”) for at least 12 months to afford users sufficient time to migrate to the new service.

6.4.4 The group agreed that, to avoid any misunderstanding, the new service should be called “Secure SADIS FTP service”, instead of “SADIS FTP Secure service”. In this regard, the group formulated the following decision:

Decision 15/17— Naming of the secure version of SADIS FTP (SADIS FTP Enhancement “Phase 2” to “Secure SADIS FTP”

That, in order to prevent any possible confusion relating to the methodology used to implement security features in the new SADIS FTP service, it be known as “Secure SADIS FTP”.

Note. – The phrases “Secure FTP” and “FTP Secure” have specific and incompatible meanings with regard to particular security protocols. In order to remove as far as possible the risk of confusion, the word “secure” and the abbreviation “FTP” should be separated, - hence “Secure SADIS FTP”.

SADISOPSG/15


6.4.5 The group noted the progress report prepared by the SADIS Provider State. It was noted that the key requirements of a secure SADIS FTP Service were to mitigate against the following risks, i.e. the reception of:

a) corrupt data from an invalid source, instead of original data from a legitimate source;

b) forged or fake data from an apparently legitimate source, but in reality a fake source; or

c) original data from a legitimate source, but data which is incomplete or inaccurate.

6.4.6 With regard to the details of a secure SADIS FTP Service, the group considered the following five future options together with the corresponding estimates of costs: “Digital Signing”, “HTTPS”, “SFTP”, “FTPS” and “status quo”. The group noted the results of the assessment (estimated costs in brackets) which indicated that:

a) Digital Signing. This option was the one initially proposed at the SADISOPSG/14 Meeting; it would meet to the highest level the security requirements in terms of data integrity and authenticity. It was the only option that could fully provide proof of integrity of data (either through malicious or accidental modification of data), and ultimately full non-repudiation protection. (Costs: £67000 ± £13000, as notified to Chairman of the SCRAG at the SCRAG/10 Meeting);

b) HTTPS (Hyper Text Transfer Protocol Secure). It was noted that the HTTPS protocol was used for secure online transactions and provided confidentiality in the sense that the user could be assured that they had connected to the SADIS Provider State’s servers. However, it did not provide absolute proof that a document transmitted from the provider had been received intact by the user. Since alerting SADIS users for potential corruption or tampering was considered critical, the HTTPS was not considered appropriate for SADIS. (Costs: £44000 ± £4000);

c) SFTP (Secure Shell (SSH) File Transfer Protocol). The group noted that the SFTP encrypted both commands and data, providing effective protection against common network security risks and preventing the casual detection of the username, password or any other transmitted data. However, it did not provide the absolute proof of integrity or authenticity of the data, and was not therefore considered appropriate for SADIS. (Costs: £39000 ± £4000);

d) FTPS (FTP with Transport Security Layer (TSL) and Secure Socket Layer (SSL). It was noted that that with FTPS, the control session would always be encrypted, while the data session might not be. This option was ruled out on the basis that it did not provide absolute proof of integrity or authenticity of the data, considered essential by the group. (Costs: £39000 ± £4000); and

e) Status quo. The status quo scenario would not provide confidentiality or the proof of data integrity, and was not therefore considered to meet the minimum requirements for SADIS as stipulated in Doc 9855. (Costs: no additional expenditure).

SADISOPSG/15


6.4.7 Concerning the delivery times, the group was pleased to note that the SADIS Provider State could complete the delivery as expected at the SADISOPSG/14 Meeting (i.e. by November 2010).

6.4.8 Based on the considerations under 6.4.6 a) to e) and the recommendation by the SADIS Provider State, the group concurred that option a) above should be selected as it would best meet the requirements for data integrity, authenticity and non-repudiation protection. The group therefore formulated the following conclusion:

Conclusion 15/18 — Development of Secure SADIS FTP service (“Phase 2”)

That,

a) the SADIS Provider State, in coordination with the SADIS Technical Developments Team, proceed with the development of a Secure SADIS FTP service (“Phase 2”), implementing Digital Signing of files as the methodology for enhancement of security of the data; and

b) the Chairman of the SADISOPSG be invited to inform the Chairman of the SCRAG that the estimated cost for implementation of Phase 2, implementing Digital Signing, remain at £67 000 ± £13 000.

Note 1. – Phase 2 will benefit from dual server capability, and incorporate security enhancements in accordance with doc 9855, Guidelines on the Use of the Public Internet for Aeronautical Applications; and

Note 2. – Phase 2 is expected to be operational by November 2010 (Amendment 75 to Annex 3) and will run in parallel with the existing SADIS FTP Enhanced service (“Phase 1”) for at least 12 months to afford users sufficient time to migrate to the new service.

User registration

6.4.9 The group agreed that a registration process needed to be established to be sure that only authorized users were given access to the service, and that full records were kept in order to appropriately manage the access to the data delivered by the Secure SADIS FTP service. The group took note of the rationale behind the need for registration which would concern both existing and new SADIS FTP users.

6.4.10 With regard to the timescales, the group noted that the intention was to commence the “invitation process” during the four-month period prior to implementation (November 2010), with a second round of invitations two months before implementation. The invitations would be direct contact via all known e-mail addresses related to SADIS. The group recalled that there would be a period of

SADISOPSG/15


parallel running of the Phase 1 and Phase 2 services for at least one year; therefore, it would not be necessary to have all users registered by the implementation date of Phase 2.

6.4.11 The group also reviewed and endorsed a proposed registration form for the Secure FTP service, and formulated the following conclusion:

Conclusion 15/19 — Implementation of Secure SADIS FTP service registration/re-registration process

That, in order to implement a process of inviting SADIS users to register for the Secure SADIS FTP Service, the SADIS Provider State:

a) post invitations for registration to all known users via e-mail, via SADIS adminstrative messages and the SADIS Administration Message Board 4 months and 2 months before implementation date of the service;

b) provide, on request by a SADIS user, the Secure SADIS FTP Service User Registration Form, provided in Appendix F to this report; and

c) process and implement new user accounts accordingly for the Secure SADIS FTP service.

Note. - Dependent on the adoption of the Secure SADIS FTP Service by users, the SADIS Provider may initiate further “invitation to register” exercises at its discretion during the first 6 to 9 months of implementation of the new service.

SADISOPSG/15-DP/7


Agenda Item 7: Long-term planning of SADIS

7.1 The group recalled that it had formulated Conclusion 11/22 calling for the SADIS Provider State to elaborate and maintain a concise long-term plan for the major development of the SADIS system, covering a period of five years, for review and endorsement by the SADISOPSG. It was also recalled that the group had formulated Conclusion 12/22 calling for the SADIS Provider State to include an estimate of the scope (i.e. major versus minor) and nature (i.e. hardware and/or software impacted) of the changes on SADIS users as part of the long-term plan.

7.2 The group was pleased to note that an update to the long-term plan had been prepared by the SADIS Provider State. It paid due consideration to the life expectancy of SADIS related services and systems and also took into account the amendment cycle of Annex 3 – Meteorological Service for International Air Navigation in order to minimize the frequency of changes, and the corresponding operational and financial implications to the users. Furthermore, the SADIS Provider State had ensured that the updates to the plan were harmonized with the equivalent WAFS 5-year plan that had been developed by the WAFC Provider States and endorsed by the WAFSOPSG. To assist workstation vendors and users alike to better understand the proposals outlined in the long-term plan, additional background information had been included in the long-term plan.

7.3 The group reviewed the updates to the plan and formulated the following decision:

Decision 15/20 — SADIS long-term plan 2011-2015

That, the concise long-term plan covering a period of five years, given in Appendix G to this report be endorsed.

Note. - The long-term plan is a planning tool and certain milestones are still subject to formal endorsement by the SADISOPSG or WAFSOPSG.

7.4 In connection with the long-term plan, the group also addressed the long-term strategy of the SADIS prompted by the recent developments, i.e. the planned cessation of the international satellite communications system (ISCS) broadcast by 2012 and the request by the SCRAG to reduce SADIS costs by 20 per cent.

7.5 Concerning the future requirements for satellite broadcasts, it was noted that the expected future requirements for OPMET information (including expected changes to data formats) were likely to lead to a situation where the SADIS 2G satellite broadcast system could no longer meet the operational requirements. Furthermore, the group realized that the hardware components of the SADIS broadcast infrastructure had a lifetime of around five years and that therefore around the year 2015, a major refresh/upgrade to the satellite infrastructure (possibly including user receiver equipment) would have to be undertaken. In view of the foregoing, it was agreed that the need for continued satellite broadcast beyond the year 2015 should be assessed by the group based on views of SADIS user States and users. The group formulated the following conclusion:

SADISOPSG/15-DP/7

7-2 Report on Agenda Item 7

Conclusion 15/21 – Consultation of SADIS user States and users concerning the need for continued satellite broadcast beyond 2015

That, the Secretariat

a) consult SADIS user States and users on the need for continued satellite distribution of OPMET data (including WAFS forecasts) beyond 2015; and

b) report back the results of the consultation for consideration and future action by the SADISOPSG/16 Meeting.

Note. – The reasons for questioning the future of satellite broadcast (i.e. high costs inherent to satellite distribution and the foreseen need for a major update in 2015 of the infrastructure supporting the satellite broadcast) are to be indicated in the State letter.

7.6 The group noted that, irrespective of the future considerations of the satellite broadcast, the SADIS FTP service would become one of the key means by which OPMET data was received by SADIS users; it was therefore considered that a review of the system architecture would be required. In particular, it was considered that the need for a back-up to the SADIS FTP service in case of interruption should be assessed. In this context, the group formulated the following conclusion:

Conclusion 15/22 — Back-up to the Secure SADIS FTP service That, the SADIS Provider State, in coordination with the SADISOPSG Technical Developments Team, prepare proposals for establishing contingency arrangements related to the technical infrastructure at the SADIS Provider State for the Secure SADIS FTP service, in time for the SADISOPSG/16 Meeting.

7.7 In view of reducing costs by some 20 per cent, as called for by the SCRAG, the group considered a proposal by the SADIS Provider State to eliminate some services and facilities provided at the SADIS Gateway (i.e. elimination of real-time monitoring, helpdesk and data searches and reduction of the configuration updates to twice per year only). While these proposals would go a substantial way towards meeting the aspiration of the SCRAG to reduce SADIS costs by 20 per cent, they would have a detrimental impact on the availability, reliability and quality of OPMET information on the SADIS and were not therefore supported by the group, including IATA. It was recalled that in Annex 3 it was the responsibility of the Contracting State to implement proper quality management of meteorological information to be supplied to the users. However, considering the current quality status of OPMET data received by SADIS, such changes could lead to the multiplication of costs by user States and users since the quality control of OPMET data would have to be undertaken by individual users instead of the current centralized approach. Moreover, the group felt that savings had already been made through action taken

SADISOPSG/15-DP/7(Draft)


by this meeting (e.g. giving up of the satellite bandwidth, reductions in staff costs) which would decrease the overall costs by some 6 per cent.

SADISOPSG/15


Agenda Item 8: The SADIS User Guide

8.1 The group recalled that it had endorsed the new fourth edition of the SUG at its thirteenth meeting (Decision 13/22 refers) which had brought about major changes, i.e. those emanating from Amendment 74 to Annex 3 — Meteorological Service for International Air Navigation and the phasing out of the satellite distribution system for information relating to air navigation (SADIS) 1G broadcast.

8.2 Since the SADISOPSG/14 Meeting, changes had been made to the SUG which reflected:

a) the introduction of GRIB2 data, proposed for transmission later in 2010 (subject to endorsement by the group);

b) the change of issue times of significant weather (SIGWX) medium-level BUFR data and SIGWX PNG charts in order to bring them into line with the issue time of SIGWX high-level BUFR, and

c) a change to the timeliness of delivery of these products under back-up.

8.3 Furthermore, following the refresh of the ICAO web-pages related to the SADISOPSG and World Area Forecast System Operations Group (WAFSOPSG), there were many URLs that were no longer valid. The opportunity had also been taken to correct one or two minor typographical errors, and also updated Appendices B (simplified topology) and H (rendering the example compatible with Amendment 74 to Annex 3).

8.4 The group reviewed the updated SUG (including Appendices B and H) available on the SADISOPSG website, endorsed their contents and formulated the following decision:

Decision 15/23 — Amendments to Chapters 1 to 7 and Appendices B and H of the SADIS User Guide

That, the amended SADIS User Guide (including Appendices B and H) given at

www.icao.int/anb/sadisopsg/sug/SUG-English/SUG-4th-EN.pdf

be endorsed.

8.5 The group agreed that other amendments to the SUG were not required.

Agenda Item 9: Future work programme

9.1 Under this agenda item, the group undertook the customary review of its work programme.

9.2 The group noted the composition of the group and its terms of reference and recalled that the terms of reference reflected the overall tasks of the group and needed to be revised only when major changes were introduced to the SADIS programme. Furthermore, any change (except for editorials and factual changes) would have to be subject to a draft conclusion to be endorsed by all the planning and implementation regional groups (PIRGs) concerned. It was agreed that there was no need to amend the terms of reference at this meeting.

9.3 The group reviewed its work programme expressed in terms of deliverables. When reviewing the work programme, the group updated the following elements:

a) future work programme (2010 to 2014);

b) executive summaries for each recurrent task; and

c) terms of reference of the following teams;

1) SADISOPSG Gateway Development Team;

2) SADISOPSG Strategic Assessment Team; and

3) SADISOPSG Technical Developments Team.

9.4 It was noted that, prior to the meeting, the work programme had been subject to editorial improvements which did not influence its substance.

9.5 The group reviewed the work programme, endorsed the changes proposed and formulated the following decision:

Decision 15/24 — Future work programme of the SADISOPSG That, the deliverables of the group be updated as shown in Appendix H to this report.

Note. - The Secretariat will place the updated work programme on the SADISOPSG website.

Agenda Item 10: Any other business

SADIS 2G data losses and their mitigation

10.1 The group recalled that at its fourteenth meeting the ongoing data losses on the SADIS 2G broadcast had been addressed (Decision 14/17 refers). The group noted with some concern that the SADIS Provider State was not in a position to state categorically that the issue of data losses on the SADIS 2G broadcast that occurred during the transmission part of the process had been completely resolved. It was, however, noted that important steps had been made towards finally resolving the issue, which were detailed in a report by the SADIS Provider State.

10.2 Based on the report provided, the group concluded that the SADIS Provider State, with assistance from the SADIS Technical Developments Team and VADOS (AEP Networks), had made substantial progress in determining the reasons for the historical ongoing data loss issue, and measurable improvements to the completeness of SADIS 2G broadcasts could be expected in the future.

10.3 In order to complete action on this important issue, the group formulated the following conclusion:

Conclusion 15/25 — Implementation of corrective actions to eliminate data losses in the SADIS 2G transmission

That, the SADIS Provider State,

a) continue to implement the necessary corrective actions to eliminate residual data losses in the SADIS 2G transmission process; and

b) report progress to the Secretariat by 29 July 2010.

UK Met Office information related to volcanic ash

10.4 In view of the recent volcanic eruption in Iceland and its impact on aviation, the group noted that the SADIS Provider State would make available, in response to requirements by some users, national volcanic ash forecasts issued by the UK Met Office on the SADIS FTP service with the understanding that their inclusion would have no impact on the availability and timeliness of the required OPMET data (including WAFS forecasts) on the SADIS FTP service, nor would they have any cost implications. These forecasts would be supplemental and would not form part of the forecasts provided within the IAVW. It was further noted that the inclusion of this information in the SADIS FTP service would be reconsidered if any unforeseen problems occurred.

Future meetings

10.5 The group reconfirmed that it continued to be necessary to schedule annual meetings of the group for the foreseeable future. Regarding the venue for the next meeting in 2011, it was noted that

SADISOPSG/15

10-2 Report on Agenda Item 10

the group had held meetings in ICAO regions served by SADIS on a rotational basis. Since the last four meetings had been held in Bangkok (2007, 2009), Dakar (2008) and Paris (2010), the group noted that the SADISOPSG/16 Meeting should be held at the MID (Middle East) Regional Office in Cairo, Egypt. Therefore, the Secretary was tasked to investigate the possibility of holding the SADISOPSG/16 Meeting in the MID Regional Office, Cairo, 23 to 25 May 2011.

Acknowledgements

10.6 The group expressed special thanks to the members of the SADISOPSG Gateway Development and Technical Developments Teams, and to the IATA Member of the group who had contributed towards the progress of a number of key issues.

10.7 The group also took the opportunity to express its appreciation to the SADIS Provider State, and Mr. C. Tyson, in particular, for his support both during the past year. His role was considered to be essential in the management of the highly successful SADIS Programme.

Appendix A [to the registration form]: Frequently Asked Questions Q1: When will the Secure SADIS FTP Service commence? A1: The Secure SADIS FTP Service will commence in November 2010. Q2: When will the existing SADIS FTP Service cease? A2: The existing SADIS FTP Service will run in parallel with the new Secure SADIS FTP Service for

at least one year. Q3: How will I know when I need to switch to the new Secure SADIS FTP Service? A3: You will have a least one year to obtain software updates to allow access to the new service.

Workstation Providers have indicated that patches will allow users to access both services during the period that both services are offered. This will allow a gradual take up of the new service over 1 year.

Q4: Will I need to obtain a new workstation to access Secure SADIS FTP? A4: No. We will be working with all of the SADIS Workstation Vendors, and it is expected that they

will be able to provide software updates. Q5: Our organization developed its own software to access SADIS FTP, how will we access Secure

SADIS FTP? A5: There is the opportunity to indicate this on the Registration Form. We will be able to supply

sufficient details to allow access to the data. Q6: Will the data be different? A6: No. The data will not be different. The process of obtaining the data will be largely transparent,

and SADIS workstations, once updated, should be able to access the new site transparently. Q7: Why is this Secure SADIS Service being introduced? A7: It is necessary to comply with regulatory requirements in order to ensure that the data is delivered

to users with high integrity. Q8: Why is so much detail required? A8: The new service is intended to be very secure, and will make it very difficult for any unauthorised

user to gain access to the service. Because our records go back many years and original contact names are sometimes no longer valid, we must ensure that the all applications for access to the new service are from authorised users. Only authorised users will be able to provide answers to the questions we ask. Also, this will allow us to update our records so that we can provide a better to service to all users.

Q9: I cannot answer all the questions – will this prevent me obtaining access to the Secure SADIS

FTP service? A9: Not necessarily. If you answer as many questions as you can, we may be able to confirm that you

are an authorised user. If not, we will contact you to advise what questions require fuller answers, and how you may obtain those answers.

BACKGROUND INFORMATION RELATED TO SADIS MILESTONES (2011-2015)

To assist workstation vendors and users alike to better understand the proposals outlined

in this long-term plan, additional background information has been prepared by the SADIS Provider State:

1. Initially, the GRIB 2 code form WAFS upper air forecasts (including icing, turbulence and CB

clouds) were disseminated on the SADIS FTP service only. At the SADISOPSG/15 Meeting, it was agreed that the GRIB 2 products will be provided in parallel with GRIB 1 forecasts on the SADIS 2G satellite broadcast (except for those related to icing, turbulence and CB clouds)

2. SADIS workstation vendors and flight planning systems will be afforded over 4 years of GRIB 2

data availability, in parallel with GRIB 1, to develop systems that are capable of accepting, processing and visualizing GRIB 2 WAFS data. End-user systems would be expected to be upgraded to handle GRIB 2 before the GRIB 1 data is eventually withdrawn from all services.

3. Following endorsement by the SADISOPSG/14 Meeting, the SADIS Provider State has

commenced development of a Secure SADIS FTP service that will benefit from dual server capability and enhanced security features. This new service will necessitate a re-configuration or upgrade of end user workstations, since pre-existing login credentials are not expected to work on the new server. Secure SADIS FTP will be expected to be available as an operational service by November 2010. Users will be afforded a parallel running period of the pre-existing and secure SADIS FTP services, to allow them to update their systems. Subject to endorsement by the SADISOPSG/16 Meeting, the legacy service will be withdrawn in November 2011 in view of the operational implementation of the Secure SADIS FTP service, including migration of users.

4. WAFSOPSG/5 Meeting (September 2009) resulted in requirement for continued development of

the gridded forecasts for CB clouds, icing and turbulence before they could be considered operationally acceptable, and both WAFCs continue to progress this work. As a consequence, but also from the user’s stated preferences, there was an ongoing requirement for SIGWX data to provided in a format similar to that provided currently, i.e. a simple two-dimensional schematic illustrating in an easy to digest form the SIGWX features to be encountered en route. As such, the proposed cessation of the format of the SIGWX BUFR/PNG formats is to be determined by the WAFSOPSG; pending this decision it has been deleted from the long term plan.
