What is the purpose of an Audio Control Panel (ACP)?

• A. To select which radio is used for transmission and to receive from any number of radios.
• B. To tune the navigation radios.
• C. To control the interphone.
• D. To set the flight path

Answer: (A)

An Audio Control Panel is all about how cockpit audio and radio communications are managed. Its main job is to let you choose which radio you transmit on and to hear audio from the radios you’re monitoring. In practice, you can route transmit and receive audio from any supported radio and direct it to the captain’s or first officer’s headset or speaker, often while you listen to multiple radios at once. Tuning the navigation radios isn’t done there; that’s handled by the Radio Management Panel. The ACP does include interphone control, but the essential function described here is selecting the transmit source and routing receive audio. Setting the flight path is done by the navigation and flight-management systems, not the ACP.
