Which statement is true about who tunes the navigation radios?

• A. The RMP normally tunes the navigation radios.
• B. The ACP tunes the navigation radios.
• C. The SVCE tunes navigation radios.
• D. The FMGS normally tunes the navigation radios.

Answer: (D)

The navigation radios are normally tuned by the FMGS. Because the FMGS handles the active flight plan and approach data, it automatically sets NAV1 and NAV2 to the frequencies required for the current leg or approach, keeping the radios in sync with what the aircraft is intended to fly. This automation reduces workload and minimizes the chance of mismatched frequencies. If manual tuning is needed, the RMP can be used to override or set specific frequencies, but under normal operation the FMGS handles the tuning. The ACP is used for audio functions, and the SVCE is not involved in tuning the navigation radios.
