Description
The audio integrating system provides an interface between crew microphones,
speakers, headphones, and the aircraft’s radio, warning and recording systems. The
audio integrating system also provides an interface between any or all flight crew and
ground crew stations.
Components and Operation
The audio integrating system consists of the following components:
• two flight crew jack panels
• three ground crew interphone units (jacks)
• two speakers
• two audio control panels
Flight Crew Jack Panels
Two flight crew jack panels (Pilot and Copilot) are located in the flight compartment.
Ground Crew Interphone-Jack Units
The three ground crew interphone-jack units are installed in the following locations:
• nosewheel well
• main avionics bay
• aft equipment compartment
Each assembly is a metal-case sealed unit which has one microphone jack and one
headphone jack. The microphone jacks in the nosewheel well and aft compartment are
deactivated in flight by the WOW switch.
Speakers
Two independent speakers are mounted in the roof of the flight compartment for the
pilot’s and copilot’s audio systems. The speakers allow audio monitoring without the
use of headphones.
