Flight Data Recorder
Description
The flight data recorder (FDR) records aircraft flight parameters. The FDR system
includes a digital FDR, an underwater locator device (ULD) and a triaxial
accelerometer. (See also Chapter 6 Communications)
Components and Operation
The FDR is located in the aft equipment bay and records the last 25 hours of flight data
in a solid-state memory. The FDR is specially constructed to survive the shock of an
aircraft crash. It is automatically turned on when the right engine start switch is
pushed.
FDR EVENT Switch
The FDR EVENT switch is located on the PASS SIGNS and EMER LTS panel. When
the FDR EVENT switch is pushed, the DCUs place a marker into the FDR memory for
quick data retrieval of the recorded event. A green advisory message FDR EVENT is
then displayed on the secondary EICAS page.
