Who defines aircraft emergencies to provide standard descriptions and terminology?

• A. IC
• B. FAA
• C. ATCT
• D. JAA ARFF OIC

Answer: (B)

Clear, universal emergency terminology for aviation is set by the FAA. This regulatory body defines what counts as an aircraft emergency, the levels of urgency, and the standard phrases used to report and describe conditions so pilots, controllers, and responders can communicate quickly and precisely. The goal is consistent understanding across all parties during a high-stress event, which helps coordinate actions and safety.

The role of an Incident Commander is to manage the on-scene response, not to define the terminology. Air Traffic Control Towers use the established FAA/ICAO phraseology, but they don’t set the terms themselves. The JAA ARFF OIC refers to a specific position within a regional authority and isn’t the body that defines terminology for U.S. aviation emergencies.
