Which system normally tunes the navigation radios?

Which system normally tunes the navigation radios?

• A. FMGS
• B. Radio Management Panel (RMP)
• C. SVCE
• D. Audio Control Panel (ACP)

Answer: (A)

The FMGS handles navigation radio tuning. It coordinates the flight plan and guidance data with the NAV radios so that the active route, leg transitions, and approaches automatically tune the appropriate NAV frequencies, reducing pilot workload. The Radio Management Panel is the manual interface pilots use if they need to change frequencies themselves, but the normal, automatic tuning is performed by the FMGS. The other systems shown (SVCE and ACP) are not responsible for tuning NAV frequencies.
