OVRD - Restores pack operation with engines mismatched.
AUTO - Both packs automatically shut down if either engine fails during
takeoff; the respective pack shuts down if the heat exchanger cooling is
insufficient; the left/right pack shuts down if the conditioned air supply to the
cockpit/cabin is too high.

The MTC
compensates for nosedown pitching moments that are generated during operation
at high Mach numbers. MTC function can be inhibited by moving MACH TRIM
COMP switch to OVRD.
|
|
|
Term
|
Definition
OFF - Yaw damper operation is disabled if AP is disengaged. If AP is
engaged, yaw damper operation is automatically provided.
ON - Yaw damper operation is provided with AP engaged or disengaged.
OVRD - Inhibits yaw damper operation with AP engaged or disengaged.

Auxiliary pump is protected from overheat damage by a thermal
protective circuit that automatically shuts the pump off when
exceeding normal operating temperature. OVRD position bypasses
the protective circuit to permit continuous pump operation when
needed.
