Question 0

How do you stop a runaway stab trim?

Answer 0

Opposite force on the yoke.

Question 1

Which has priority, electric trim or ALTN STAB TRIM?

Answer 1

ALTN STAB TRIM interrupts all other stab trim commands.

Question 2

What do the STAB TRIM CUTOUT switches do?

Answer 2

The STAB TRIM CUTOUT switches remove hydraulic power from their respective modules, C and R.

Question 3

At what rate does the autopilot trim the stab?

Answer 3

The autopilot trims the stab at 1/2 normal rate because it only uses one trim module at a time.

Question 4

What will happen if you use the electric stab trim switches with and autopilot engaged?

What happens with 2 or 3 autopilots engaged?

Answer 4

With one autopilot engaged using the electric stab trim switches will disconnect the autopilot.

With 2 or 3 autopilots engaged nothing will happen.

Question 5

When will the speed brakes extend upon landing?

Answer 5

With the trucks not tilted the speed brakes will deploy from the ARMED position when both thrust levers are at idle.

With the trucks not tilted the speed brakes will deploy from the DOWN position when either thrust reverser is deployed.

Question 6

When do the slats move to mid range?

Answer 6

The slats move to mid range when the flaps are selected to 1 through 20.

Question 7

If a stall is sensed with the flaps set from 1 to 20 what happens?

Answer 7

To help prevent a stall the slats will extend from mid range to full extend.

Question 8

If you exceed the Max flap extension speed for flaps 30 what happens?

Answer 8

The flaps move from 30 to 25 to provide load relief. They will move back to 30 when below the Max speed.

Question 9

What happens if you get either a LEADING or TRAILING EDGE light?

Answer 9

Either light will cause both the slats and the flaps to stop and the flap handle to become inoperative.

Question 10

What type of leading edge protection does the 757 have?

Answer 10

Both asymmetry and disagreement protection.

Question 11

What types of protection do the flaps have?

Answer 11

The flaps have asymmetry, disagreement and load relief protection.

Question 12

What happens when you arm either the LE or TE switch?

Answer 12

Hydraulic pressure is removed from both slats and flaps.

Selected electrical motor is armed to operate according to ALTERNATE FLAPS SELECTOR position.

Flap handle is disabled.

Full slats will extend at flaps 20 position.

Question 13

What protections do you have while using the ALTERNATE FLAP MODE?

Answer 13

In ALTERNATE FLAP MODE you only have slat asymmetry protection.

Question 14

What does an illuminated STAB TRIM annunciator light indicate?

Answer 14

Stab trim is at 1/2 normal rate.

Question 15

What does an illuminated SPOILERS annunciator light indicate.

Answer 15

An illuminated SPOILERS annunciator light indicates one or more pair of spoilers are not in the commanded position.

Question 16

What does a AUTO SPEEDBRAKE annunciator indicate.

Answer 16

A fault in the auto speed brakes.

Question 17

MACH SPEED TRIM annunciator illuminated means?

Answer 17

A fault in mach speed trim.

Question 18

If an UNSCHED STAB TRIM annunciator light illuminates what does it mean?

Answer 18

You have a wrong way trim or a runaway trim.

Question 19

RUDDER RATIO annunciator illuminated means?

Answer 19

A fault in the rudder ratio system.

Question 20

ANTISKID annunciator illuminated means?

Answer 20

A fault in the ANTISKID system.

Question 21

If you have a yaw damper INOPERATIVE light illuminated what does it mean?

Answer 21

A fault in the yaw damper

The yaw damper switch is off

IRS is not aligned

Question 22

SPEEDBRAKES light means?

Answer 22

Speedbrakes are extended below 800 RA
Or
Flaps are in the landing position, 25 or 30.
