Audio Control Panel Controls

The audio control panels (ACPs) lets the crew listen to ILS station audio or the morse code station identifier.

You use the ACP receiver switches to select the ILS audio you want to listen to. The NAV 1 receiver switch selects the MMR 1 audio and the NAV 2 receiver switch selects the MMR 2 audio. The filter switch lets you listen to only voice audio in the voice (V) position. The range ® position lets you listen to the station morse code identifier. With selector in the both (B) position you can listen to both the voice audio and the morse code station identifier.
