 FLIGHT DATA RECORDER SYSTEM - DESCRIPTION AND OPERATION
_______________________________________________________
 1.  General (Fig. 1)_______
 A.  The digital flight recorder system records selected flight parameters including FAA mandatory parameters. The recording contains data for the last 25 hours of airplane operation.
 B.  GUN 001-008, 010, 101 PRE-EO B531006; GUN 009; The Flight Data Entry Panel (FDEP) is also installed on the flight recorder system.

 D.  All input signals are connected to the DFDAU. The DFDAU conditions the input signals to produce a digital output which is sent to the DFDR for recording. The recorded data is stored in a crash protected container inside the DFDR.
 E.  The system is turned on automatically when the airplane is in flight, or on the ground when an engine is running. The system may also be turned on manually or tested by means of a switch on the FDEP or the FRCP.
 F.  The flight recorder system is monitored continuously by BITE during operation. System failures are displayed on the FRCP or the FDEP and on the DFDAU and EICAS.
