AMF Competency 3 description

Competence description
Warnings are issued in a timely manner when hazardous meteorological and other relevant environmental phenomena are occurring, expected to occur or when parameters are expected to reach documented threshold values. They are updated or cancelled according to documented warning criteria.

Performance Assessment criteria

3.1. Forecast the following hazardous weather phenomena, including spatial extent, onset, duration, and intensity: 

3.1.1 thunderstorms, particularly organized systems, including associated turbulence, in-flight icing, hail, heavy precipitation with poor visibility, electrical phenomena, down-burst/microburst or gust front, tornadic activity 

3.1.2 turbulence (moderate or greater), including onset and duration, intensity, spatial extent, type (orographic, mechanical, convective and clear air turbulence). 

3.1.3 moderate and severe low-level wind shear 

3.1.4 aircraft icing (moderate or greater), including onset and duration, intensity, accumulation rate, spatial extent, type (rime or opaque, glaze or clear, freezing rain, hoar frost, mixed ice) 

3.1.5 hazardous phenomena affecting aerodromes such as: strong surface winds including cross-winds and squalls, frost, freezing precipitation, snowfall, lightning, wake vortices 

3.1.6 sand- and dust storms 

3.1.7 volcanic ash based on observations and/or advisory products 

3.1.8 tropical cyclones.

3.2. Ensure that warnings are prepared and issued in accordance with thresholds for hazardous weather, and with ICAO Annex 3, WMO-No.49, regional and national formats, codes and technical regulations on content, accuracy and timeliness. 

3.3. Ensure that warnings of hazardous weather phenomena are consistent (spatially and temporally) across boundaries of the area of responsibility as far as practicable, whilst maintaining meteorological integrity. This will include monitoring forecasts issued for other regions, and liaison with adjacent regions as required.
