Microphone Jacks
There are two identical microphone jack assemblies which are mounted by the left and right side
consoles. They are used to interface the pilot’s headset and microphones with the airplane
communication and navigation systems. A stowage boot and microphone jack are also provided on
each pilot’s control yoke for operation and stowage of the hand mic.
Flight Compartment Speakers
Some audio outputs cannot be muted and are, therefore, always heard over both speakers regardless
of the speaker selection on the audio panels. The flight compartment unmuted audio system has an
emergency bypass circuit between the ACP and VHF COMM NAV which will produce aural warning
tones through the speakers.
Oxygen Mask Assemblies
There are two identical oxygen mask assemblies located above the left and right side consoles. The
assemblies contain microphone connectors which provide the flight crew with an additional method of
voice communication.
