A

Flight deck interface unit
Interfaces VHF and nav audio
Speaker-muting for the PA system

Hardware interface to the commercial VHF radios and the navigation audio for the flight deck and the mission crew member.
The FDIU also provides access to the VHF radio and one of the mission V/UHF radios (in UHF mode) for emergency operation. The FDIU provides speaker-muting for the PA system. When a crew member keys the PA system, the PA speakers in the vicinity of that crew member are muted to prevent feedback.
