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

How well did you know this?

Perfectly

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

Cancels an alert for landing with flaps less than 30 degrees

The trailing edge flaps are normally operated by
