ADF stands for

• A. Airborne Direction Finder
• B. Automatic Direction Finder
• C. Aircraft Data Facility
• D. Air Defense Facility

Answer: (A)

A radio navigation instrument used in aircraft to determine the bearing to a non-directional beacon. The name highlights that it is on board the aircraft (airborne) and that its function is to find direction (direction finder) to the beacon. While you’ll often hear about the automatic aspect because the bearing is displayed automatically, the standard expansion for this acronym in many training materials is Airborne Direction Finder. The other options describe different facilities or concepts (data facility, air defense facility) that aren’t the navigation instrument discussed here.
