DESCRIPTION
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,
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 hours data, at least. It stores this data on a fireproof and
shockproof device. An underwater Iocator beacon is attached to the DFDR.
The linear accelerometer measures the acceleration of the aircraft along each of the three
axes.
The OAR is an operational 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 the ground, during the first five minutes after the aircraft electric network is
energized.
- On the ground, after the first engine start.
- In flight (whether the engines are running or not).
On the ground, the recording system stops automatically five minutes after the second
engine shuts down.
On the ground, the crew can start the recording system manually by pressing the GND CTL
pushbutton.
