What does decoding the NAVAID Morse code allow you to verify?

• A. The correct frequency for the navaid.
• B. The aircraft's altitude.
• C. The ILS glide slope.
• D. The flight director mode.

Answer: (A)

Decoding the NAVAID Morse code helps you confirm you’re tuned to the correct navigation aid. Each VOR/LOC/NDB broadcasts a Morse identifier that uniquely identifies the station. When you decode that ID and it matches the published ident for the station you intended to use, you know you’re receiving the right navaid on its designated frequency. This verification ties the frequency you’ve selected in the nav radio to the actual station you expect to rely on for navigation. If the Morse ident doesn’t match, you’re not on the intended beacon. The other options—altitude, ILS glide slope, or flight director mode—aren’t determined by the Morse ident of a navaid.
