Meteorology
This domain tests weather knowledge needed for VFR flight in Kuwait: atmosphere, pressure, wind, stability, clouds, icing, thunderstorms, dust, and METAR/TAF interpretation. Kuwait’s desert climate brings extreme summer heat, strong north-westerly shamal winds, blowing dust and low visibility, and occasional convective storms.
Core rules
- Pressure decreases with altitude; altimeter setting is critical. QNH gives elevation above mean sea level; QFE gives height above a reference point.
- Stability: unstable air favours showers, thunderstorms and turbulence; stable air favours haze, stratiform cloud and smooth conditions.
- Icing: structural icing requires visible moisture and freezing temperatures; carburettor icing can occur above 0°C.
- Thunderstorms: avoid by at least 20 nm where possible; expect gust fronts, wind shear, hail and microbursts.
- METAR is current observed weather; TAF is a forecast. Check validity, wind, visibility, cloud, temperature/dewpoint and QNH.
Worked example
METAR OKBK 121200Z 32012KT 5000 BLDU 38/12 Q1004. Decode: 12th day, 1200 UTC; wind 320° true at 12 kt; visibility 5,000 m; blowing dust; temperature 38°C, dewpoint 12°C; QNH 1004 hPa. The temperature/dewpoint spread is large, so low-level humidity is low, but blowing dust reduces visibility and can damage the engine and pitot system. Plan for reduced VFR visibility and possible dust ingestion.
Traps that cost marks
Reading TAF as current weather; confusing QNH and QFE; assuming clear skies mean no turbulence; ignoring density altitude in 45°C heat; and treating blowing dust as harmless when it can cause low visibility and engine wear.
