There are two systems of communication from the cockpit to the cabin :
- the Passenger Address (PA) system for passenger announcements,
- and the cabin interphone system to talk to a cabin attendant.

System Presentation 5/41
In addition, there is a calls system which enables :
- the cockpit to call the ground mechanic and the cabin crew,
- the ground mechanic or the cabin crew to call the cockpit.

Note : The evacuation command system, which is also
part of the communication system, will be discussed in the
cabin presentation.

Control of all radio communications is achieved through Radio Management
Panels (RMP) and Audio Control Panels (ACP).
Let’s start with the RMP.
RMP ACP
COMMUNICATIONS MENU
System Presentation 8/41
The RMPs provide tuning of all radios.
There are two RMPs located on the
center pedestal and an optional third one
on the overhead panel.

We will now look at the different controls and indications of the RMP :
- The ON/OFF switch controls its power supply,
- the radio selection keys enable the pilot to select a radio to
modify a frequency,

- the ACTIVE window displays the active frequency,
- the standby (STBY) window displays the standby frequency,
- the dual rotary knob enables the pilot to change the STBY frequency,
the outer knob for the megahertz, and the inner knob for the decimals,
- and the transfer key exchanges the STBY and ACTIVE frequencies.

System Presentation 15/41
The standby navigation (STBY NAV) keys provide backup navigation
tuning in the event of dual FMGS failure.
These keys will be discussed in the navigation chapter.

System Presentation 16/41
On the A320, any RMP can tune any communication radio but each
one is normally dedicated to a particular radio :
- RMP 1 to VHF 1,
- RMP 2 to VHF 2,
- RMP 3 to VHF 3 or HF 1.

System Presentation 17/41
The SEL light illuminates white when a pilot selects a radio on
an RMP which is not dedicated to that RMP. This will be explained
in more detail in the normal operation module.
RMP 1

System Presentation 18/41
As we have seen, the RMPs tune the
desired radio frequencies.
Let’s now look at the ACPs which
provide control of radio transmission and
reception.

There are three ACPs, each located next to an RMP :
- two on the center pedestal,
- an optional third one on the overhead panel.

Let’s look at the different controls of the ACP.
The transmission keys enable you to select any radio or interphone system.
A green light illuminates on the selected key.
Only one transmission key can be selected at a time.

The CALL light flashes amber with a buzzer when a SELCAL is received on the
applicable radio (VHF or HF).
The MECH light flashes amber with a buzzer when a call is initiated by the
ground mechanic.
The ATT light flashes amber with a buzzer when a call is initiated from any
flight attendant station through the cabin interphone system.
The RESET key silences any buzzer and extinguishes the flashing amber light
associated with any of these calls.
