FAA Aircraft Dispatcher Complete Practice Exam

An AIRMET is a type of weather advisory used by the FAA primarily to inform pilots about moderate weather conditions that may present hazards during flight. This includes phenomena such as moderate turbulence, moderate icing, and other conditions that might not meet the criteria for a SIGMET, which addresses more severe weather hazards. By providing this information, the AIRMET helps pilots to make informed decisions about their flight operations.

While severe thunderstorms and severe icing are critical concerns for pilots, those conditions are specifically covered under different advisories, namely SIGMETs. Major air traffic delays are also not the focus of an AIRMET, as it does not deal with traffic management issues but rather with the safety concerns related to weather phenomena that could impact flight safety and comfort. Therefore, the AIRMET is crucial for alerting pilots to moderate weather hazards, which is the purpose of the advisory.
