What does ADF stand for?

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

Answer: (C)

In this context, the acronym is interpreted within a defense or warning framework. Air Defense Facility refers to a ground-based setup that watches airspace, integrates radar and other sensor data, and coordinates responses to potential aerial threats. It provides warning and command-and-control functions for defense operations. The other options describe items associated with navigation rather than a defense installation. Automatic Direction Finder is a navigational instrument used with non-directional beacons to determine bearing, typically found on aircraft or in air/nav aids. Airborne Direction Finder would be a device located on an aircraft, not a fixed facility. Aircraft Data Facility isn’t a standard term in this context. So the term that best fits a defense-related facility is Air Defense Facility.
