Flight Controls Flashcards
757/767: The three modes of stabilizer trim control are:
Electric (control wheel) alternate (control stand) automatic (autopilot)
757/767: If pilots inadvertently activate aileron trim while an autopilot is engaged, the repositioning of the aileron neutral point:
Is not apparent until the autopilot is disengaged
757 Selection of flaps 1 commands the
Slats to move to takeoff position and flaps extend to 1
757/767 the UNSCHEDULED STAB TRIM light illuminates when
Stab trim movement without signal from trim switches
When spoilers light is illuminated it indicates
One or more spoiler system faults detected
767 AIL LOCK is illuminated. If this were to illuminate during low speed flight what would be the status of ailerons
One or more of the ailerons failed to unlock
757/767: With the speed brake lever in the ARMED position, the ground spoilers automatically extend upon landing and the handle moves to the UP positions when three conditions are met, including:
Both truck tilt sensors detect a no-tilt condition on the ground
757/767: The AUTO SPD BRK light is illuminated with the speed brake lever positioned to ARM.
indicates that:
Speed brakes may not extend automatically on landing or rejected takeoff or may extend in flight if additional fault occurs
757/767: The RUDDER RATIO light is illuminated, this indicates:
A fault in the rudder ratio system
The __ trim switches are inhibited if multiple autopilots are engaged in the approach mode
Electric
The flap position indicator displays
Left and right flap and slat position
767: The Pitch Enhancement System (PES) provides a backup source of hydraulic power to operate the horizontal stabilizer if both the left and center hydraulic systems fail. When the PES operates, trim is only available from the:
Control wheel trim switches
757: It during the Before Takeoff Procedure, the stabilizer trim setting shown on FMC TAKEOFF REF page 1 is less than 3.0, what should be done?
Use the ALTN STAB TRIM switches
757/767: The rudder ratio system varies control authority from the rudder pedals and trim modules based on airspeed. The system is powered by the
hydraulic system.
Left
757: If the flaps 30 airspeed placard limit is exceeded, the flap load relief system will automatically have the flaps:
The flaps automatically retract to position 25 and when airspeed is reduced below the placarded limit, the flaps automatically re-extend to position 30
757/767: If a single autopilot is engaged, ____ trimming causes the autopilot to disengage
Electric
757/767: The stabilizer is controlled automatically by the autopilot or the Mach speed trim system.
When either the autopilot or mach speed trim system is trimming, can the STAB TRIM light illuminate?
No, the light is inhibited when autopilot or Mach/speed system is engaged
767 Selection of flaps 1 commands the
Slats to move to takeoff and flaps to remain retracted
757/767: The speed brake lever is aft of the armed position and radio altitude is between 800 feet and 15 feet RA. The ___ light will illuminate.
Speed brakes
767: If the flaps 30 airspeed placard limit is exceeded, the flap load relief system will automatically have the flaps:
The flaps automatically retract to position 20. Flaps are re-extended to the selected position when the speed is reduced below the associated limit.
757: When the TRAILING EDGE light illuminates, hydraulic power is removed from the drive unit(s) of
Slats and flaps
767: In conjunction with trailing edge flap position 5 (or greater), which of the following will droop by being hydraulically driven to 50% down?
Inboard ailerons
