The TACAN receiver/transmitter performs which functions?

• A. Receive and Transmits coded RF pulses, decodes received pulses to extract bearing, range, and ID tone
• B. Transmits only
• C. Receives only
• D. Generates display data

Answer: (A)

TACAN works by exchanging coded RF pulses with a ground station, performing two-way communication. The transmitter sends interrogation signals and the receiver picks up the station’s replies. The bearing (azimuth) information comes from the coded pulse pattern of the azimuth transmitter, while the range is determined from the timing of the interrogation and reply (the DME function). The receiver also decodes the identification tone that identifies the station. The data are then used to display bearing and range to the pilot. That combination—transmitting and receiving coded RF pulses and decoding them to extract bearing, range, and ID tone—is exactly what the TACAN receiver/transmitter does.
