extinguishes A/T disengage lights after automatic A/T disengagement.
Takeoff/Go–Around (TO/GA) Switches
Push – engages AFDS and A/T in takeoff or go–around mode if previously armed.
Forward Thrust Levers
Controls engine thrust.
Cannot be advanced if the reverse thrust lever is in the deployed position.
Reverse Thrust Levers
Controls engine reverse thrust.
Cannot select reverse thrust unless related forward thrust lever is at IDLE.
Note: Reverse thrust lever is blocked at reverse idle position until related thrust reverser is more than 60% deployed.
Note: Movement of reverse thrust lever into reverse thrust engages locking pawl preventing forward thrust lever from moving. Terminating reverse thrust removes locking pawl and restores forward thrust lever movement ability.
Engine Start Levers
IDLE –
energizes ignition system through EEC
electrically opens spar fuel shutoff valve in the wing leading edge outboard of the pylon
electrically opens engine–mounted fuel shutoff valve via the EEC.
CUTOFF –
closes both spar and engine fuel shutoff valves
de–energizes ignition system.
Note: Illuminate (red) in the event of engine fire or during an engine fire test.
CAUTION: Do not apply rotational force when moving the engine start lever.
Stabilizer Trim Wheel
Provides for manual operation of stabilizer
Overrides any other stabilizer trim inputs
Rotates when stabilizer is in motion.
Note: Handle should be folded inside stabilizer trim wheel for normal operation.
Stabilizer Trim Indicator
Indicates units of airplane trim on the adjacent scale.
Stabilizer Trim Green Band Range
Corresponds to allowable range of trim settings for takeoff.
Stabilizer Trim PRI (primary) Cutout switch
NORMAL – normal operating position
CUTOUT – stops stabilizer trim inputs from main electric, autopilot and Speed Trim System (Speed Trim function and MCAS function).
Stabilizer Trim B/U (backup) Cutout switch
NORMAL – normal operating position.
CUTOUT – stops stabilizer trim inputs from main electric, autopilot and Speed Trim System (Speed Trim function and MCAS function).
PARKING BRAKE Lever
Forward – parking brakes released.
Aft – sets parking brakes when either Captain’s or First Officer’s brake pedals are fully depressed.
Parking Brake Warning Light
Illuminated (red) – parking brake is set (light operates from battery power).
Extinguished – parking brake is released.
Landing Gear Warning Cutout Switch
Push – silences landing gear configuration warning aural indication at flaps up through 10 and above 200 feet RA.
Note: The aural indication cannot be silenced with the cutout switch at flaps greater than 10.
