FAA Commercial Pilot Airplane (CAX)WeatherEasy
A pilot is preparing for a cross-country flight and reviews the latest Area Forecast (FA). The FA indicates 'OCNL TSRA VCNTY FLG'. What type of weather is being forecast, and where is it expected?
- AOvercast skies with light rain, near Flagstaff.
- BOccasional towering cumulus with light rain, visibility decreasing.
- CScattered thunderstorms with heavy rain, very close to Flagstaff.
- DOccasional thunderstorms with rain, in the vicinity of Flagstaff.
Show answer & explanationAnswer & explanation
Correct answer: D. Occasional thunderstorms with rain, in the vicinity of Flagstaff.
'OCNL' stands for occasional, 'TSRA' for thunderstorms with rain, and 'VCNTY FLG' for vicinity of Flagstaff. This is a direct interpretation of standard aviation weather abbreviations.
Why the other options are wrong
- A. 'TSRA' specifically means thunderstorms with rain, not just overcast skies and light rain.
- B. While thunderstorms are related to towering cumulus, 'TSRA' is more specific. 'Visibility decreasing' is not indicated by 'VCNTY FLG'.
- C. 'OCNL' means occasional, not scattered. 'TSRA' is thunderstorms with rain, not necessarily heavy rain, and 'VCNTY' means vicinity, not very close.
