English for Aviation Meteorology
Core concepts
Candidates must read and interpret technical English in aviation meteorology: METAR, TAF, SIGMET, and PIREP texts. Focus on vocabulary such as 'ceiling', 'visibility', 'overcast', 'broken', 'freezing level', and 'wind shear'. Understand abbreviations and codes used in aviation weather messages. Practice comprehension of operational documents and standard phraseology.
Traps
Questions often test the difference between 'ceiling' and 'cloud base', and between 'broken' and 'overcast'. Be careful with the meaning of 'gusts' and 'variable' winds. Do not confuse 'forecast' with 'observed'.
Worked example
A METAR reading 'BKN020 OVC050' indicates a broken layer at 2000 ft and overcast at 5000 ft. The ceiling is the lowest broken or overcast layer, so the ceiling is 2000 ft. This distinction matters for alternate aerodrome planning.
