D. Crash and Fire Protection
The Crash Survivable Memory Unit (CSMU) is designed to fully meet the 5,000
pounds crush test requirement of TSO–123a and provides impact protection for up
to 3400 g's for 6.5 msec. The inner steel casing assembly protects the memory ele-
ments from deep sea pressures to 20,000 ft.
The FA2100's crash–protected CVR memory survives ED–56A 5.3.2.d. and ED−112
2−4.2.4 High Temperature Fire for one hour per the requirements of TSO-123a, or
ED–56A 5.3.2.e., ED−112 2.4.2.5 Low Temperature Fire for ten hours. Specifically, 1
Hr @ 1100_ C, and 10 Hrs @ 260_ C.
E. Torque Requirements
The following assembly items have the specified torque requirements:
CSMU & Beacon Bracket mounting screws (75 in./lbs.);
Chassis Cover screws (9-10 in./lbs.); and
Rear Panel, Aircraft Interface & Acquisition Processor attaching screws (5-6 in./lbs.)
