memory to a water depth of twenty thousand (20,000) feet.
D. DFDR Maintenance Ground Override Switch:
The DFDR maintenance ground override switch is located on the Right
Electrical Equipment Rack (REER) on the system monitor test panel, and
is labeled FDR MAINT GRD OVRD. If the aircraft is stationary and the
Weight-On-Wheels (WOW) system is in the GROUND mode, placing the
switch in the OFF position will inhibit recording by the DFDR while aircraft
engines are operating. If the switch is inadvertently left in the OFF position,
transfer of WOW to the AIR mode (such as during takeoff) automatically
returns the switch to the AUTO position, enabling DFDR recording. Manual
positioning the switch to the AUTO position is also possible.
E. DFDR / CMC EVENT Switch:
The FDR / CMC EVENT switch is located on the cockpit overhead panel.
When momentarily depressed, an event stamp is placed on the FDR tape.
When the event switch is depressed, the Central Maintenance Computer
(CMC) saves a data block of information that spans from 30 seconds prior
to switch activation and continues for one minute following release of the
switch. A blue Event Record advisory message is also displayed on the
Crew Alerting System (CAS).
