OutlineOutline

• Objectives of MFAA* participation to OWS7

• Volcanic Ash and aviation

• MFAA achievements... (and newbies' feedback)

• Possible way forward

*Météo-France, Alticode, Atmosphère

Objectives Objectives (as per MFAA proposal)(as per MFAA proposal)

• Contribute to implement weather service provision in OWS7 operational scenarios, by providing prototype components of:• WFS, based on Meteo-France actual Aviation Forecast production;• FPS• Client on a hand-held device

• Focus on the delivery of Volcanic Ash SIGMETs (other hazards SIGMETs possible over a limited area, TAF/METAR within French airspace)

• Interconnect with other partners' components (agreed at OWS7 Kick-Off meeting)

Volcanic Ash Clouds / AviationVolcanic Ash Clouds / Aviation

• Mount Galunggung (1982): B742 4 engine shutdown on flight BA009 (13 minute glide from F370 to F130)

• Mount Redoubt (1989): B744 4 engine shutdown on flight KL867 (80 M$ glide)

• Eyjafjalla volcano (2010): largest air traffic shut-down since WWII


OGC®

• Rock spray

• Mainly composed of silicates

• Melting point: ~ 1100°C/2000F

• Particles size: ~ 1-100 µm

• Hardness index: 5 - 7 (Mohs scale)

WHAT ARE VOLCANIC ASHES ?

OGC®

Effects on AirplanesEffects on Airplanes

• Possible interferences with communication systems

• Surfaces abrasion: sandblast cockpit windshield, leading edges, Pitot-static tube, antennas...

• "Ashes" melt within the engines' combustion chamber, then adhere to various parts, clogging ducts, reducing air flow...

Limited instructions (until recently):

DON'T FLY near or inside a VA cloud!


OGC®

Airspace Users Information NeedsAirspace Users Information Needs

• Hazards caused by a volcanic eruption are nearly instantaneous

• VA clouds spread over large areas and move at non-negligible speeds

• "See and avoid" not an option!

Creation of Volcanic Ash Advisory Centers by WMO+ICAO

VAACs' role VAACs' role (as per ICAO annex 3)(as per ICAO annex 3)

• Monitor satellite data to detect the existence and extent of volcanic ash in the atmosphere, within its area of responsibility;

• Run dispersion models to forecast the ash cloud trajectory;

• Issue advisories (cloud extent & movement) to concerned MWOs, other VAACs, ACCs, NOTAM offices, and interested airlines.

MFAA Achievements in OWS7MFAA Achievements in OWS7


• Implementation of the 3 prototype components• Meteo-France WFS (1.1), serving SIGMETs (VA and

more), at: http://137.129.19.1/WS/ows7/

• Alticode FPS, portraying VA clouds (and more), at: http://www.alticode.net/OWS7/

• Atmosphere hand-held client, displaying SIGMETs of interest (and more), demo accessible at: http://galbn1.atmosphere.aero/

• Contribution to WXXM 1.1 validation through operational utilization

• Interconnection with a few other partners' components

OGC®

Difficulties encountered by newbiesDifficulties encountered by newbies


• "How am I supposed to use that generic complex fit-for-all meta-stuff?"

• "Oops, my routine sample doesn't fit!"

• Learning curve is steep, at least initially (i.e. the first 4 months or so)... and experienced partners keep running faster and farther ahead!

OGC®


WXXM VA SIGMETsWXXM VA SIGMETs

• WXXM - A few changes required in the model for the accommodation of VA SIGMETs:• Missing attribute or parameter (e.g. area,

phenomenonType)• More significant: an observation and a forecast cannot

currently be jointly inserted in WXXM SIGMETs

• WFS - Retrieval of ICAO product hardly compatible with the data-centric approach

OGC®

Naive Feedback on OGC Services Naive Feedback on OGC Services


• More realistic (i.e. complex) examples would be extremely helpful in specifications...

• Implementing all possible options did not seem to be an option compatible with the targeted test-bed schedule

• Keeping up with fast evolving specifications (multiple versions) is – at best – challenging!

• Having the FPS concept spread over several other specification documents is a potential source of troubles

OGC®

and yet...and yet...


• A decent end-to-end service could be set up in just a few weeks, with some of its components implemented from scratch

• Interoperability achieved in spite of a relatively light co-ordination amongst partners spread over the world (and often barely knowing each other)

• OGC's genuine added value and potential have been felt...

• ... MFAA partners are willing to take on new challenges!

OGC®

Suggestions for Future WorkSuggestions for Future Work


Components upgrade + accommodation of more recent versions

• Test the component's usability in other environments:• complementary WXXM features• AIXM, other...

• Implement more advanced access mechanisms (e.g. SOAP)

• Extend capabilities to handle meteorological gridded data (CPS)

• Go on with WXXM validation activities, aiming at short term implementation of operational WXXM services (SESAR)
