Study Notes
Aircraft Communication System
- Enables communication between crew, ground stations, cabin crew, passengers, and ground mechanics.
- Uses VHF and HF radios, a Public Address (PA) system, and a cabin interphone system for various communication needs.
- Call systems facilitate cockpit calls to/from ground mechanics or cabin crew.
- Cockpit Voice Recorder (CVR) records cockpit communications and warnings for the last 2 hours.
Communication Control Panels
- Radio Management Panels (RMPs) are located on center and overhead panels.
- Manage active/standby radio frequencies.
- Backup tuning for navigation aids during dual FMGC failure.
- Dedicated to specific radios (e.g., RMP1 → VHF1).
- "SEL" light indicates radio selection by another RMP.
- Audio Control Panels (ACPs) support radio/interphone selection and volume control.
- Only one radio/interphone can be active at a time.
- Interphone/Radio Switch allows for internal (INT) or radio (RADIO) communication.
- Voice Key suppresses navigation signals.
- PA Key enables announcements.
Call and Communication Features
- Amber indicators (CALL, MECH, ATT, SAT CALL) for various calls.
- Separate volume control for external communication and interphone.
- CVR records cockpit audio and warnings automatically for the last 2 hours.
Failure Management
- RMP failure results in a blank display.
- Use a functioning RMP for radio tuning.
- ACP failure shifts audio control to ACP3 via overhead switch.
- "AUDIO 3 TRANSFERRED" memo confirms the switch.
Cockpit Voice Recorder (CVR)
- Automatic operation: Starts 5 minutes after aircraft power-on, stops until engine start, continues during flight, and shuts off 5 minutes after engine shutdown.
- Pre-flight test: Ensure Ground Control is ON, parking brake is set, and press/hold CVR Test button until tone is heard.
Passenger Announcements (PA)
- Methods include using the PA transmission key on the ACP and the cockpit PA handset.
Radio Communication with RMPs
- Any RMP can tune any radio.
- Cross-selection is indicated by "SEL" lights on both RMPs.
- Active frequencies update on both RMPs, but standby frequencies remain independent.
- VHF reception buttons and volume controls.
- Transmission via INT/RADIO Switch (RADIO position) or sidestick/hand mic PTT.
Ground Mechanic Calls
- Amber MECH light and buzzer alert crew to a ground mechanic call.
- Call automatically cancels after 60 seconds or when reset button is pressed.
- Hot mic (INT position) and PTT are used for ground communication.
Interphone Setup
- Interphone reception knob and volume adjustment for cockpit/ground communication.
