From the TACAN pulses, which data is decoded?

• A. Bearing, range, and ID tone
• B. Bearing only
• C. Range only
• D. Frequency spectrum

Answer: (A)

The pulses from a TACAN give you three pieces of data: the bearing to the station, the range (distance), and the station’s identification tone. The bearing comes from the azimuth information encoded by the TACAN’s directional antenna system, which your receiver interprets as the angle to the station. The range is obtained through the DME function, where the time delay between interrogation and reply is converted into distance. The identification tone is a Morse-coded ID transmitted by the TACAN so you can confirm which station you’re receiving. Frequency spectrum isn’t the decoded data you use for navigation here.
