TACAN offers 3 modes, what are they?

• A. Transmit, Receive, Nav-Assist
• B. Receive, Transmit/Receive, Air-to-Air
• C. Radar, Sonar, Infrared
• D. Transmit Only, Receive Only, Hold

Answer: (B)

TACAN can operate in three selectable modes that define how it handles interrogations and replies. In the listening-only mode, the unit receives interrogations but does not send a reply, which is useful for monitoring or test scenarios. In the standard operating mode, it both transmits and receives, actively replying to interrogations and providing distance (DME) and bearing information for navigation to a TACAN station. The third mode enables air-to-air use, where one aircraft can interrogate another aircraft’s TACAN and receive a reply, allowing mutual navigation or formation-use between aircraft. This combination covers typical navigation use as well as special mutual-operations between aircraft.
