8-53. CRASH/FREEZE/CRASH OVERRIDE.
8-54. All simulator action can be frozen at any instant by depressing any of the three FREEZE switchlights on the IOS or
auxiliary control panel. FREEZE lights stay on when freeze mode is active, indicating that the freeze condition can be
removed by depressing a FREEZE switchlight.
8-55. If a crash occurs, the simulator is placed in a crash freeze mode, which is indicated by illumination of CRASH
lights on the segment light panel, and by the CRASH OVERRIDE light blinking at the IOS. Depressing the FREEZE
switchlight does not override the crash status. The crash can be eliminated by initializing an IC set or bypassing it, using
the CRASH OVERRIDE switchlights, returning the simulator to a normal freeze status. (Table 8-9 lists crash limits.)
