Main electric trim speed is faster with flaps extended
What is the function of the STAB TRIM CUTOUT switches(500)
Shuts off autopilot and main electric trim motors
What action is requires to stop a runaway stabilizer trim
Move control column in opposite direction of runaway trim to remove power from both autopilot and main electric trim motors
Which statement contains some of the conditions necessary for the automatic speed trim system to function
During low speed flight, at a low gross weight, and with an aft CG, it used the autopilot stab trim to trim the aircraft
What indicates to the crew that the speed trim system is operating
Stabilizer trim wheel rotates at autopilot stab trim speed with the autopilot not engaged
How is a dual channel speed trim failure indicated
SPEED TRIM FAIL, FLT CONT annunciator, and mASTER CAUtIoN lights illuminate
Which answer best describes the operation of the rudder
Powered by either “A” ,”B”, or Standby hydraulic systems
Which statement is correct regarding the aileron and rudder trim systems
Both Hydraulic and Electrical power are required for each system to trim the aircraft
When is the Wheel to Rudder Interconnect System (WTRIS) used(7,8,9)
Manual reversion, only available when both FLT CONTROL switches are positioned to SBY RUD and the YAW DAMPER switch has been reset to ON
Which statement regarding the yaw damper system is correct
Uses “B” hydraulic system pressure and provides rudder deflection commands and turn coordination
Which actions trip the YAW DAMPER switch to the OFF position
“B” FLT CONTROL switch placed to OFF or SBY RUD
What is the hydraulic power source for the ground spoilers
“A” system for both inboard and outboard ground spoilers
Which action causes the flight spoilers to deploy at touchdown with the speed brake lever ARMED
Wheel spin- up occurs on any two main wheels
What occurs after touchdown when all spoiler panels are deployed and either throttle is advanced
The SPEED BRAKE lever automatically moves to the down detent and all Ground and Flight spoilers retract
All spoiler panels extend when a takeoff is rejected above 60 kts and
The reverse thrust levers are positioned to reverse thrust
What does an illuminated SPEED BRAKE ARMED light indicate
Speed brake lever is selected to ARMED with valid system inputs
When approaching a stall angle of attack, what does the autoslat system provide
Automatic slat extension to the “full extend” position with trailing edge flaps at the 1 through 5 positions
When is the Power Transfer Unit (PTU) activated with flaps 1 through 5 selected
Loss of system “B” engine driven pump pressure
How does the Power Transfer Unit provide power for the autoslat system
Allows system “A” pressure to power a hydraulic pump which pressurizes system “ B” fluid
What is the max altitude for flap extension
20000 ft
Which statement is correct for operation of the alternate flap system
No asymmetry protection is provided and LE devices cannot be retracted
With an amber LE TRANSIT light on ( normal conditions), which other light(s) will illuminate on the forward panels
None
At cruise, what does an illuminated AUTO SLAT FAIL light, MaSTER CAUTION light, and FLT CONT light indicate(No Recall)
A dual channel autoslat computer failure
What occurs when the alternate flap position switch is held in the down position with the ALTERNATE FLAPS master switch in the ARM position
Electric motor extends trailing edge flaps, and the leading edge control valve opens to hydraulically extend the leading edge devices
Speedbrakes inflight
Should not be deployed at RA less than 1000’ nor with flaps extended beyond 15 degrees
With the loss of hydraulic system A and the FEESl DIFF PRESS light illuminated, the elevator feel system is still operative
False
With normal hydraulic system pressure indications, placing either FLT COnTROL switch to the SBY RUD position, should cause the respective flight control LOW PRESSURE light to illuminate, the extinguish
True
The takeoff config warning horn will sound if a takeoff is attempted with the speed brake lever in the SPEED BRAKE ARMED position
True
With the flaps set at 5 for takeoff, which leading edge annunciator will be illuminated on the center instrument panel
LE FLAPS EXT
With the SPEED BRAKE DO NOT ARM light illuminated before landing, the speed brake lever should be manually moved to _____ after touchdown
Up (all the way back)
The Yaw Damper uses(500)
“B” system hydraulic pressure only
When the leading edge devices are extended with the ALTERNATE FLAPS Position Switch, the LE slats extend to FULL EXT regardless of TE flap position
True
The MACH TRIm FAIL light, in conjunction with the MASTSeSr CAUTIOn and the System Annunciator FLT CONT light, illuminate if a dual channel failure of the Mach trim occurs
True
What function does the flap load limiter system provide(500)
It causes the flaps to move from 40 degrees to 30 degrees in event of excessive airspeed
With the hydraulic A system flight control switch in STBY RUD
The Standby hydraulic pump is activated
The trailing edge flaps are at 15 degrees. The correct indication on the aft overhead panel for the leading edge devices is
Leading edge devices( slats) FULL EXT lights are illuminated green
Duty cycle for alternate flap extension to greater than 15 degrees and back to 0 degrees is(one cycle is down and back up)
1 cycle - 25 minutes off
Speed brakes should not be used with flaps greater than 15
True
The elevator FEEL DIFFERENTIAL PRESSURE light is inhibited when
The flaps are extended
A trailing edge assymetry is sensed
In the trailing edge flap position indicator
The ground spoilers are powered by the “A” hydraulic system and
Can only be powered by the “A” hydraulic sustem
The FLAP INHIBIT position of the GPWS switch
Cancels an alert for landing with flaps less than 30 degrees
The trailing edge flaps are normally operated by
The “B” hydraulic system
When does the 800 Wheel to Rudder Interconnect System begin to operate
Manual reversion
Avail only when both FLT CONTROL switches are positioned to SBY RUD and the YAW DAMPER switch has been reset to ON
