Which panel can be used to monitor the audio or ID from a navigation radio?

• A. ACP
• B. MCDU
• C. PFD
• D. EICAS

Answer: (A)

The Audio Control Panel is the interface used to monitor audio from cockpit radios, including the navigation radios, and to hear the ident (Morse code) for those signals. It lets you select which audio sources you want to listen to, adjust their volume, and route them to the cockpit speakers or headsets. The navigation radio’s audio and its ident come through the ACP so you can verify the correct VOR/ILS signal and identify the station if needed. The other panels serve different roles: the MCDU is for data input into the flight management system, the PFD displays primary flight data, and the EICAS shows engine and warning information. So the panel that handles monitoring the audio and ID from a navigation radio is the Audio Control Panel.
