FAA Aircraft Dispatcher Practice Exam

Which of the following is a condition described in an AIRMET?

1. Sustained winds of 25 knots

2. Ceilings less than 2,000 feet

3. Widespread areas of ceilings less than 1,000 feet

4. Extreme turbulence

The correct answer is: Widespread areas of ceilings less than 1,000 feet

An AIRMET (Airmen's Meteorological Information) is a type of in-flight weather advisory that addresses potentially hazardous weather conditions, primarily aimed at pilots of smaller aircraft. It provides information on weather phenomena that may not meet the criteria for a SIGMET but still pose a significant risk. The correct answer identifies widespread areas of ceilings less than 1,000 feet as a condition described in an AIRMET. This is particularly important for pilots since low ceilings can significantly affect visibility and flying conditions, increasing the risk of flight operations, especially for general aviation flights. AIRMETs are issued to inform pilots about these widespread low ceilings, making it essential for flight planning and safety. Sustained winds of 25 knots and ceilings less than 2,000 feet are conditions that might be relevant for aviation but typically are not conditions specifically classified within AIRMETs. While these may warrant caution, they generally do not rise to the level of issuing an AIRMET unless the criteria indicate a greater hazard. On the other hand, extreme turbulence is covered by SIGMETs rather than AIRMETs, as SIGMETs address severe, less frequent weather phenomena that can affect all types of aircraft, particularly during conditions that are more dangerous or
