COMPONENTS
The radio communication system in the Challenger 300 consists of the following:
-Two VHF communication transceivers
-Two VHF communication antennas
-HF antenna (optional)
-Two radio integration units
-Two audio control panels
-Two maintenance interphone panels
AUDIO CONTROL PANELS (ACPs)
An audio control panel (ACP) is located on both sides of the instrument panel. The ACPs allow the pilots to monitor the navigation radios, monitor and transmit on VHF and HF communication radios, the PA system and intercom system.
Receiver controls and volume adjustment for the intercom and radio are provided at each ACP. The output from each audio control panel is directed to the associated headset jacks and speaker.
The aural warning system volume is not adjustable by the crew. Audio signals from the aural warning system, TAWS, and TCAS do not go through the volume control switches.
Headphone audio is always available, with the volume control capability from any control switch.
SPKR
The SPKR audio selector enables the selected audio to be routed to the on-side crew speaker. Warning audio can be heard with the switch in any position.
INPH
The INPH audio selector enables intercommunication between the crew positions in the cockpit and service interphone positions external to the aircraft.
VOICE/ID/BOTH
The VOICE/ID/BOTH toggle switch is a three position toggle switch that allows the pilot to separate the audio when mon-itoring the simulcast audio of a radio transmission. When the switch is selected to VOICE, the VOR, ILS, or ADF station morse code identifier is filtered out, allowing only the voice signal to be audible. In the ID position, only NAV and ADF identifier code will be heard. When BOTH is selected, the station morse code identifier and voice message are audible.
EMER/NORM
The EMER/NORM is a two position locking toggle switch. In the NORM position, the audio system operation is normal. In the EMER position, the audio is routed directly to the headphones.
