FLIGHT DATA RECORDER
The Flight Data Recorder (FDR) is a crash survivable data recorder capable of retaining up to
25 hours of airplane parameters/flight data. The FDR system consists of:
• Solid state flight data recorder.
• High-G accelerometer.
The High-G accelerometer is mounted in the airplane landing gear bay and provides the normal
acceleration data for the FDR system.
The DAU 4 receives airplane parameters/flight data from various systems and normal acceleration
input from a dedicated accelerometer. The FDR receives its systems information from DAU 4 and
sends status information back to the DAU 4. A FDR self-test is performed on airplane power-up and
if a failure is detected at any time (including self-test), an advisory message will be displayed on
EICAS.

QUICK ACCESS RECORDER (IF INSTALLED)
The optional Quick Access Recorder (QAR) is an independent flight data recording devise that
records the same data as the FDR. The QAR can retain up to 750 hours of airplane parameters/flight
data. If a QAR failure occurs, the FDR FAIL message will be displayed on EICAS.

UNDERWATER LOCATOR BEACON
An Underwater Locator Beacon (ULB) is attached to the CVR as part of the handle to help locate it in
the event of a crash.

The ULBs operating frequency is 37.5 KHz and will operate for 30 days.
EMERGENCY LOCATOR TRANSMITTER
The Emergency Locator Transmitter (ELT) consists of:
• ELT switch.
• Emergency locator transmitter.
• ELT antenna.
A flight compartment switch located on the overhead panel provides “ON” and “ARM” modes of
operation. The switch can be used to manually activate the ELT for test purposes or emergency
situations.

LIGHT SENSOR - ELT PANEL (CONT'D)
The ELT transmits signals on 121.5, 243.0 and optional 406.025 MHz. The 406.025 MHz may be
installed as part of the ELT and its signal is transmitted for satellite relay. Upon activation, the 121.5,
243.0 signals operate continuously until the self contained battery pack power is exhausted (typically
last at least 72 hours) or the unit is reset. If the optional 406 MHz transmitter module is installed, the
output signal is transmitted for 24 hours (once every 47 seconds) then automatically shuts off. The
121.5, 243.0 signals are shut off while the 406 MHz signal is transmitting.

An internally mounted “G” switch is triggered on impact and activates the ELT. The ELT antenna is
mounted on the top aft exterior of the airplane and interfaces with all signal outputs. When the ELT is
transmitting, a signal is sent to the transmitter to DAU 2. This signal used by the DAU provides an
ELT transmitting advisory message to EICAS.

AIRBORNE DATA LINK SYSTEM
Airborne Data Link System (ADLS) operation is via the third VHF comm, UHF (telephony) or
SATCOM and controllable from all FMS CDUs. The system utilizes the same data loading unit as the
FMS with printer interface, air−ground−air and air−to−air capabilities. Crew advisory messages are
displayed on the CDU scratch pad.
