Aircraft Automatic Direction Finding Test Equipment (ADF Testers / Simulators)

The Automatic Direction Finder (ADF) is a critical piece of Aircraft navigation equipment, used to automatically calculate the relative bearing of an aircraft to a radio station.

The ADF consists of a loop aerial which is rotated to detect the direction of minimum reception of a specific radio frequency, relative to the direction an aircraft flying is headed. This is combined with heading information for the aircraft compass to help the pilot understand bearing position and chart their course.

These are critical for tracking desired course, and the accuracy of a unit should be tested as part of every preflight routine. Aside from preflight checks for basic functionality, ADF equipment may need to be bench tested when undergoing repair or recalibration.

An ADF indicator often has a fixed azimuth dial, that shows information from the ADF unit. A coaxial connector is generally used to connect the ADF receivers and their antennas.

Our ADF Testers undergo quality assurance procedures and are calibrated by certified technicians using NIST-traceable standards.
