SUMMARY

This document provides draft proposals of NOTAM templates related to the operational impact and limited access of airspace and routes affected by volcanic ash, with reference to the action agreed by the AISAIM Study Group/3 (Action agreed 9/3 Aeronautical information dissemination related to volcanic ash.

The templates are developed with the purpose to create harmonisation in management of NOTAM messages related to a volcano eruption, where enhancement in ICAO guidance material for NOTAM creation was proposed to the Study Group.

The templates are providing a structured order of the information that shall be inserted in item E). The structure of the free text will create a harmonised output of the NOTAM, improving the readability of the message and processing of the data by the end user.

The proposed structure is taking into account the on-going progress in the digital NOTAM developments, following the digital NOTAM Event Specification as developed by the dedicated Focus Group.



CHAPTER 1 – Introduction

1.1 Purpose of documentAs a consequence of the lessons learned by the European States AIS organisations regarding the need for harmonisation in management of NOTAM related to a volcano eruption events, the ICAO AISAIM Study group proposed that the ICAO guidance material be enhanced to include examples of a series of NOTAM related to the operational impact and limited access of airspace and routes affected by volcanic ash. The templates are intended to assist States in expediting the process of originating and issuing NOTAM for the different phases of volcanic activity, in order to harmonise the output in the messages and enhance the usability of the aeronautical information for the users.

This document provides draft proposals of a series of NOTAM templates and examples, for consideration by the AISAIM Study Group for inclusion in ICAO AIS provisions.

1.2 Structure of documentThe document provides guidance for the full range of NOTAM examples required for warnings of volcanic activity and restrictions on airspace, airports and en route operations as a result of volcanic activity, including recommended NOTAM codes.

The templates are as closely as possible based on the structured data format of the digital NOTAM specification and defined event scenarios.

Chapter 2 provides an overview of the templates and NOTAM examples that are proposed to be moved forward for inclusion in ICAO Doc 8126.

Chapter 3 provides a detailed description of the structure of the NOTAM templates and detailed instructions for how to insert the information in the templates, and again NOTAM examples.

The NOTAM templates covers the following subjects:

airspace warnings airspace restrictions aerodrome/heliport closure route portion restriction/flight levels on-ground volcanic ash on the movement area

1.3 Validation of NOTAM templates The NOTAM templates created for navigation warnings and temporary airspace restrictions in version v0.2 of the document were included in the exercise directives of the ICAO EUR/NAT Volcanic Exercise VOLCEX 11-01, 13-14 April 2011. Dissemination and reception of volcanic ash related NOTAM were part of the exercise objectives to ensure that NOTAM



was issued in accordance with the provided templates by the participating States’ NOTAM Offices. Taking into account the evaluation of the effectiveness of the NOTAM issued during exercise VOLCEX 11-01, the templates were updated in v 0.3, as well as updates to reflect the terminology used by the International Volcanic Ash Task Force (IVATF) in the delivery “ATM Volcanic Ash Contingency Plan Template”, for areas of contamination and phases of a volcanic event.

Further evaluation of the updated templates in this version will be proposed for the ICAO EUR/NAT VOLCEX, planned for April 2013.

CHAPTER 2 – NOTAM Templates

2.1 General2.1.1 Structure of NOTAM content

For each subject a short description is describing for which situation the templates can be used. It follows by a description of the structure of the NOTAM text, providing the sequence of the free text information to be inserted in item E). The structure follows as closely as possible the information elements that are defined for a dedicated digital NOTAM event scenario.

A detailed instruction of how to insert the information following the structure is provided per event in Chapter 3.

2.1.2 Filling instructions and NOTAM codes

The NOTAM examples include some instructions in completion of the qualifier line, the recommended NOTAM code and instruction in how to describe a published airspace in item E).

2.2 Navigation warnings – Warnings (W)2.2.1 Type of operational impact/event

These templates apply for the issuance of navigation warnings for volcanic activity providing as precise information as is available regarding the activity, for the pre-eruption, start of eruption, ongoing eruption and recovery phases.

The examples cover elements such as the name and geographical position of the volcano, alert code indicating the activity, the horizontal extend and base/top of reported ash cloud of operationally significance, forecast direction of movement of the ash cloud and any operationally significant information additional to the foregoing.

*) The geographical reference (coordinates lat/long) shall represent the approximate centre of a circle whose radius encompasses the whole area of influence. A radius shall be included in a way that encompasses the total area of influence of the NOTAM.

**) Definition of the area should be done by radius/circle or coordinates only. Definition of airspace by the use of geographical or administrative features such as State borders, rivers, sea shores etc) is not supported by the digital NOTAM event scenario and is therefore not recommended. If operational necessary, this can be defined by providing a simplified polygon larger than the area and excluding a neighbouring FIR, for example.

Coordinates defining the lateral limits of the area (polygon) should be enumerated in clockwise order, each point separated by space-hyphen-space. The last and the first points of the list shall be the same.

2.2.5 Recovery phase

NOTAMC shall be issued cancelling the active NOTAM and a new NOTAM (NOTAMN) shall be promulgated to update the situation for volcanic ash as soon as the volcano has reverted to its pre-eruptive status, no further eruptions are expected and no ash cloud is detectable or reported from the FIR concerned.

3.5 Airport /Heliport closure [ad.cls]3.5.1 Template

The following production rule defines the information elements that are used in order to compose the text in item E in the NOTAM that announces the airport/heliport closure due to volcanic ash contamination. For Digital NOTAM encoding, this is supported by the [AD.CLS] scenario.Although a few items are used for the event of volcanic ash contamination, for completeness or the template, all items and explanations defined for the digital NOTAM encoding for airport/heliport closure are included.

In the NOTAM examples, only the items needed are used. After the closure reason which is always “DUE TO VOLCANIC ASH CONTAMINATION”, all other items can be skipped to go directly to “note”, if such exists.



(1)If we have an ICAO location indicator, then ignore element (2a/b) “name” or “ARP”and start the first line with “type”

name (2a)If we do not have an ICAO location indicator, insert name of the airport.

ARP(2b)If we don’t have an ICAO location indicator or name of the airport, then insert the text “LOCATED AT” followed by ARP coordinates.

type(3)Insert the type of airport decoded as follows:

Text recommended for item E

Q code

“AD” QFALC/QFALT

“HELIPORT” QFPLC/QFPLT

3.6 Route portion closure3.6.1 Template

The following production rule defines the information elements that are used in order to compose the text in item E of the NOTAM announcing a temporary closure of a route portion.For Digital NOTAM encoding, this is supported by the [RTE.CLS] scenario.

route availability status(1)If route or route segment has non-permanent status (non-permanent ATS route), than we have to enter value CDR (1, 2 or 3). Otherwise insert ATS.(2)Identify the route portions concerned and repeat steps from 3 to 5 for each route portion. To identify the route portions, order the route segments associated with the Event:

first sort by the designator prefix, designator second letter, designator number,



multiple identifier of the Route that is referred to by the route formed property;

second order by identical values of start point choice or end point choice with another

segment of the same Route. Attention that it is possible to have two distinct portions

of the same route associated with the Event.

route name(3)Insert here route name (designator prefix, designator second letter, designator number, multiple identifier).start point (4)Insert here the point designator or the Navaid designator or the Airport/Heliport designator that was identified as start of a route portion at point (2) above.end point(5)Insert here the point designator or the navaid designator or the airport/heliport designator that was identified as end of a route portion at point (2) above.levels(6)If any route segment with status "CLSD" has either lower level different from "FLOOR" or upper level different from "CEILING" (the segment is not completely closed on the vertical), then insert the exact values.note (7)Any other additional information.
