August 22, 2025Aug 22 In the 777, on the ACP, what does pushing the mic/int switch on the yoke, or the acp for that matter, do?. Does it serve as just a quick way to communicate on the FLT interphone? Also, when used while in the air, does it automatically key the cabin interphone instead? (CAB on acp). Is this any different to using the handphone or the center mcdu for the interphone?
