Flight Data Recorder
The flight data recorder (FDR), located in the aft equipment bay, records aircraft flight parameters. The FDR system includes a digital FDR, an underwater locator device (ULD) and a triaxial accelerometer (see Chapter 8, Emergency Equipment).
The FDR 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.
When the FDR EVENT switch, located on the PASS SIGNS and EMER LTS panel, 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 EICAS.
