AIRMET is issued to amend what type of weather report?

• A. Area forecast
• B. Pilot report
• C. Terminal forecast
• D. Hourly observation

Answer: (A)

AIRMETs are regional weather advisories that alert pilots to significant weather hazards along en-route routes, and they are issued to amend the Area Forecast. The Area Forecast provides the broad forecast for a large region, and AIRMETs update it with current or expected conditions such as icing, moderate turbulence, or mountain obscuration that could affect flight safety. They’re not updates to airport-specific forecasts (TAF), nor are they updates to actual observed reports (METAR) or pilot-observed reports (PIREPs). So the correct relationship is that AIRMETs amend the Area Forecast.
