How is a navaid frequency automatically ID'd?

• A. The station identifier and ID are displayed above the active frequency when Morse code is decoded.
• B. The system reads the Morse aloud on the intercom.
• C. The frequency changes color to indicate ID.
• D. The ID is entered manually by the pilot.

Answer: (A)

Navaids broadcast their identity in Morse code, and the navigation receiver automatically decodes that Morse to reveal the station’s three-letter identifier. The decoded ID is then shown above the active frequency on the navigation display, so you can confirm you’re tuned to the correct facility. This automatic display streamlines verification and reduces workload; there’s no voice readout, no color-change cue, and no manual entry needed.
