GENERAL SYSTEM PRESENTATION
VHF
The Very High Frequency (VHF) system serves for short
range voice communications.
HF (Option)
The High Frequency (HF) system serves for all
long-distance voice communications between different
aircraft (in flight or on the ground), or between the
aircraft and one or several ground stations.
SELCAL (SELective CALling)
The purpose of the SELCAL system is to give visual and
aural indications to the crew, concerning calls
received from ground stations through VHF and HF
systems.
CIDS
The Cabin Intercommunication Data System (CIDS) is
designed to interface flight crew, cabin attendants,
passengers, ground service and various cabin systems
dedicated to cabin attendant or passenger use.
The CIDS is used to control, test and monitor various
cabin systems dedicated to cabin attendant or passenger
use.
PASSENGER ADDRESS
The Passenger Address (PA) allows voice announcements
to be broadcast to all passengers, from the cockpit
and cabin attendant stations through the CIDS.
INTERPHONE
There are 3 interphone systems on the aircraft:
the flight interphone, the cabin interphone and the
service interphone.
- The flight interphone system allows
communication between the flight crew members,
and between the flight crew and the ground
mechanic at the external power receptacle or
in the avionics bay.
- The cabin interphone system allows
communication between the cockpit and the cabin
attendant stations, and between the cabin
attendant stations.
- The service interphone system enables
communication between the different service
interphone jacks, the cockpit and the cabin
attendant stations.
COCKPIT VOICE RECORDER
The Cockpit Voice Recorder (CVR) records in-flight and
on-ground crew conversations and radio communications.

In the cockpit, we find:
- 3 Audio Control Panels (ACPs) for the selection
of communication systems (in transmission and
reception) and for the control of the received
audio signal levels,
- 3 Radio Management Panels (RMPs) for the
selection of radio communication and navigation
frequencies,
- 1 AUDIO SWITCHING selector for the
reconfiguration of channels, in case of ACP
failure,
- 1 CALLS panel for flight crew-to-ground
mechanic or flight crew-to-cabin attendant
calls,
- and various items of acoustic equipment.
The acoustic equipment comprises:
2 loudspeakers with volume control (1),
2 radio PTT switches (on the side sticks),
