Is a radio management panel (RMP) normally used to control the navigation radios?

• A. Yes
• B. No; navigation radios are normally tuned by the RMP.
• C. Only in direct law.
• D. No; the FMGS normally tunes the navigation radios.

Answer: (D)

In normal A320 operation, the navigation radios are tuned by the Flight Management Guidance System (FMGS). The FMGS automatically sets NAV1/NAV2 frequencies based on the active flight plan and approach, ensuring the autopilot and guidance systems receive the correct signals without manual intervention. The Radio Management Panel is available for manual radio adjustments, but it does not normally drive navigation tuning. Therefore, the FMGS tuning the navigation radios is the correct behavior.
