The priority computer compares the output parameters from the unit with its own available data by means of associated logic.

This is the minimum concentration of flammable vapors in air below which propagation of flame does not occur on contact with a source of ignition.

The purpose of the autopilot actuator is to change electrical commands from the FCC into a hydraulically controlled mechanical output.The outputs of the actuators become inputs to the aileron and the elevator power control units(PCU).

The mach trim actuator also causes the elevator to be in a more nose down position during takeoff which allows the pilots to move the stabilizer to a more nose up position.

The trailing edge flaps up limit switch sends flap position data to SMYD1.The SMYD1 uses this during yaw damping to limit rudder movement when flaps are up.

Where possible, examples, associated conditions and technique should be presented on the same page as the chart. If space is not sufficient to include the necessary information, then the page facing the chart should be used.

An “emergency” however, almost always involves a failure that requires immediate and rapid response, such as a total powerplant failure, fire or smoke, or rapid cabin decompression.

It is generally preferable to remove the damage prior to submitting information to Boeing for review except for dents on metallic and composite structures, and delamination or punctures to composite structure unless removal is already approved by SRM, CMM

The auxiliary battery and auxiliary battery charger connects in parallel with the main battery during non-normal conditions to help supply power.

They include the tail assembly ,the structures at the rear of the airplane that serve to control and maneuver the aircraft and structures forming part of and attached to the wing.

Move the IDG forward until the input shaft is free of the accessory gearbox and QAD ring, then move the IDG outboard and away from the power plant.
