Question

From which primary source should information be obtained regarding expected weather at the estimated time of arrival if your destination has no Terminal Forecast?

1) Area Forecast
2) METAR
3) TAF
4) NOTAM

Answer 1

The Area Forecast is the primary source for expected weather information at the estimated time of arrival if there is no TAF available at the destination. NOTAMs provide hazard information, while METARs are current observations, not forecasts.

Step-by-step explanation:

If the destination airport does not have a Terminal Aerodrome Forecast (TAF) available, the primary source of information regarding expected weather at the estimated time of arrival should be the Area Forecast (FA). The Area Forecast provides weather conditions over a larger region and can help estimate conditions when no TAF is issued.

While NOTAMs could provide critical, timely information about hazards or changes affecting flight operations, they are not the primary source for weather information. METARs are observations of current weather conditions but may not give a forecast for future conditions required for estimated arrival time planning.

Understanding weather information is crucial for safety and operational planning in aviation, and tools like the National Oceanic and Atmospheric Administration's forecasts have become invaluable resources in our modern world for a wide range of activities, including agriculture and aviation.
