‐ Third, press on DATE/SET : To set the month.
‐ Fourth, press on DATE/SET : To set the day.
Switch the UTC selector to INT, position and the clock will start with the seconds’ digits at 00.
Note: This process must be completed in less than one minute. Otherwise, it will be necessary to
reset the CMC, in order to synchronize the lower ECAM time display with the cockpit clock
display. Resetting the CMC is a maintenance operation.

FLT RECORDERS - FLIGHT DATA RECORDING SYSTEM
A330/A340 FLEET DSC-31-60-10 P 1/2
FCOM 19 AUG 10
DESCRIPTION
Applicable to:
The Flight Data Recording System, which records the mandatory parameters, consists of the
following components :
A ‐ Flight Data Interface Unit (FDIU)
‐ A Digital Flight Data Recorder (DFDR)
‐ A three-axis Linear Accelerometer (LA)
The FDIU collects and processes parameters from the SDACs, DMCs, FWCs, FCDCs, BSCU,
EIVMUs, FCU, the DFDR event pushbutton, the GND CTL pushbutton and the Clock.
It stores the mandatory flight parameters in the DFDR.
The DFDR can store the last 25 h data, at least. It stores this data on a fireproof and shockproof
device. An underwater locator beacon is attached to the DFDR.
The linear accelerometer measures the acceleration of the aircraft along each of the three axes.
The QAR is a recorder that stores the same data as the DFDR. However, the QAR is more
accessible for the maintenance crew.
The recording system is automatically active :
‐ On ground, during the first five minutes after the aircraft electric network is energized.
‐ On ground, after the first engine start.
‐ In flight (whether the engines are running or not).
On ground, the recording system automatically stops five minutes after the second engine shuts
down.
On ground, the crew can manually start the recording system by pressing the GND CTL pushbutton.

ON : The Cockpit Voice Recorder (CVR) and the Flight Data Recorders are active. The
ON light is on.
AUTO : The Cockpit Voice Recorder (CVR) and the Flight Data Recorders are active,
according to the logic.
The system automatically switches from ON to AUTO at the first engine start, and also in case
of an electrical transient.
