14
Q

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

15
Q

Manual reversion, only available when both FLT CONTROL switches are positioned to SBY RUD and the YAW DAMPER switch has been reset to ON

16
Q

Which statement regarding the yaw damper system is correct

A

Uses “B” hydraulic system pressure and provides rudder deflection commands and turn coordination

17
Q

Which actions trip the YAW DAMPER switch to the OFF position

A

“B” FLT CONTROL switch placed to OFF or SBY RUD

18
Q

What is the hydraulic power source for the ground spoilers

A

“A” system for both inboard and outboard ground spoilers

19
Q

Which action causes the flight spoilers to deploy at touchdown with the speed brake lever ARMED

A

Wheel spin- up occurs on any two main wheels

20
Q

What occurs after touchdown when all spoiler panels are deployed and either throttle is advanced

A

The SPEED BRAKE lever automatically moves to the down detent and all Ground and Flight spoilers retract

21
Q

All spoiler panels extend when a takeoff is rejected above 60 kts and

A

The reverse thrust levers are positioned to reverse thrust

22
Q

What does an illuminated SPEED BRAKE ARMED light indicate

A

Speed brake lever is selected to ARMED with valid system inputs

23
Q

When approaching a stall angle of attack, what does the autoslat system provide

A

Automatic slat extension to the “full extend” position with trailing edge flaps at the 1 through 5 positions

24
Q

When is the Power Transfer Unit (PTU) activated with flaps 1 through 5 selected

A

Loss of system “B” engine driven pump pressure

25
Q

How does the Power Transfer Unit provide power for the autoslat system

A

Allows system “A” pressure to power a hydraulic pump which pressurizes system “ B” fluid

26
Q

What is the max altitude for flap extension

A

20000 ft

27
Q

Which statement is correct for operation of the alternate flap system

A

No asymmetry protection is provided and LE devices cannot be retracted

28
Q

With an amber LE TRANSIT light on ( normal conditions), which other light(s) will illuminate on the forward panels

A

None

29
Q

At cruise, what does an illuminated AUTO SLAT FAIL light, MaSTER CAUTION light, and FLT CONT light indicate(No Recall)

A

A dual channel autoslat computer failure

30
Q

What occurs when the alternate flap position switch is held in the down position with the ALTERNATE FLAPS master switch in the ARM position

A

Electric motor extends trailing edge flaps, and the leading edge control valve opens to hydraulically extend the leading edge devices

31
Q

Speedbrakes inflight

A

Should not be deployed at RA less than 1000’ nor with flaps extended beyond 15 degrees

32
Q
