Background

How did the discussion on a need for the harmonization

of MET products and services for low-level flights come

about?

Meteorology Group (METG)

y Annual meeting (September)

y EUR States of accreditation and international organizations

(IATA, IFALPA, WMO, ECTRL)

y Reports directly to the PIRG ± the European Air Navigation

Planning Group (EANPG)

METG/18 (2008)

y Provision of MET services for low-level flights in the EUR

Region not harmonized

y Variety of forms and content

y Growing demand

ICAO EUR/NATOffice

Who are the MET users?

According to ICAO Annex 6 (Operation of Aircraft) Part II (International General Aviation

± Aeroplanes), a General Aviation operation is

defined as:

y ³An aircraft operation other than a commercial air

transport operation or an aerial work operation´

So, the GA community encompasses:

y Gliders and powered parachutes through to large-

non-scheduled cargo flights. For example:

Rotorcraft

Piston and jet engine fixed-wing aircraft

Gliders

µLighter-than-air¶ craft

y Private and commercial




ICAO EUR/NATOffice

Have GA user needs changed?

The single most common class of GA aircraftis:

y Fixed-wind light aircraft

But....

Main area of growth in recent decades hasbeen lighter and more affordable aircraft, such

as:

y Microlights

y Small helicopters

Plus...

Advanced avionics, including GPS navigation

and onboard weather radar

Who are the MET providers

Forecasts of en-route conditions for low-levelflights are prepared locally or regionally by

meteorological offices

Terms of reference:y Assists METG in developing proposals for amendment to

the EUR Air Navigation Plan (EUR ANP) related tometeorological services for low-level flights

Amendments to EUR ANP necessary to:

y ensure the harmonized implementation of the relevant

Annex 3 Standards and Recommended Practices (SARPs);

andy enhance the services for low-level flights throughout the

EUR Region

2009 regional survey

MET perspective:

y Status of MET information provided for low-level

flights

y 34 replies, including:

90% issue area forecasts for LLF;

60% issue AIRMET;

75% issue bespoke (non-ICAO standard) LLF forecasts

USER perspective:

y Preferences on the type of MET information for low-

level flights

y 22 replies, including: 80% preference for graphical LLF forecasts

50% preference for state of the sea and SST info

>90% would like to use standardized LLF forecasts




ICAO EUR/NATOffice

2010 user consultation workshop

Engaging the MET and LLF user communities

What are the user requirements for LLF

forecasts, now and in the future?

y Content and format?

y Parameters and thresholds?

y Validity periods and update cycle?

y Criteria for amendment?

y Availability?

Can MET service providers meet these present

and future user requirements?

How do we harmonize MET service for LLF?

y Common best practices, guidelines, etc?

y What changes are necessary to the EUR ANP?
