If radio tuning on the MCDU is not available, where can the pilot manually tune a navigation radio?

• A. On the RMP
• B. On the MCDU
• C. On the ND
• D. On the ECAM

Answer: (A)

When you can’t tune a navigation radio from the MCDU, use the Radio Management Panel. The RMP is the dedicated hardware for tuning the NAV1 and NAV2 radios on the A320. You select the radio you want to tune, use the frequency tuning control to set the desired VOR/LOC frequency, and activate or swap as needed. The ND just displays the navigation data; it doesn’t provide manual frequency entry. The ECAM is for system information, not radio tuning. So the RMP is the correct place to manually tune the navigation radios.
