Flight Controls

Question 1

When will the elevator augmentation engage?

Answer 1

When the control tabs have been displaced approx 10* nose down

Question 2

What is the stabilizer trims range?

Answer 2

2* nose down-12* nose up

Question 3

What do the dual thumb trim switches operate?

Answer 3

The primary stabilizer trim motor

Question 4

What do the alternate trim levers operate?

Answer 4

The alternate trim motor

Question 5

Which trim motor does the autopilot use?

Answer 5

The alternate trim motor

Question 6

When will you hear a vocal warning regarding the stabilizer?

Answer 6

If the stabilizer is moved by the autopilot at a rate of 2* or greater in 30 seconds

Question 7

What does the Primary Stabilizer Trim cutout switch do?

Answer 7

Interrupts “release power” to the primary brake and renders the primary trim system inoperative

Question 8

When will you hear an audible signal for the horizontal stabilizer?

Answer 8

Once for every 1/2* of stabilizer movement by any method

Question 9

What do the control wheels operate for roll?

Answer 9

Aileron Control Tabs that “fly” the aileron

Flight spoilers (after 5* of control wheel travel)

Question 10

How many degrees is panel extension during ground spoiler operation?

Answer 10

60*

Question 11

How many degrees is panel extension during flight spoiler operation?
(Inflight speed brakes)

Answer 11

Approx 35*

Question 12

Which hydraulic system do the Inboard Flight Spoilers operate on?

Answer 12

Left Hydraulic system

Question 13

Which hydraulic system do the Outboard Flight Spoilers operate on?

Answer 13

Right Hydraulic System

Question 14

Which hydraulic system do the Ground Spoilers operate on?

Answer 14

Both Hydraulic systems

Question 15

What operates the rudder in the Powered mode?

Answer 15

Right Hydraulic System through the rudder control valve

Control tab is locked into a faired position, rudder and control tab move as single unit

Question 16

What controls the rudder in Manual mode?

Answer 16

Rudder pedals operate the rudder control tab which “flies” the rudder

Question 17

What does moving the Rudder Hydraulic Control Lever into the Manual position do?

Answer 17

Removes hydraulic pressure from the rudder (RUDDER CONTROL MAN Annunciator)

Question 18

What does the rudder throw limiter do?

Answer 18

Varies allowed rudder travel based on speed

High speeds= rudder travel limited

Low speeds= rudder travel unrestricted “Rudder Travel Unrestricted”

Question 19

How can yaw damper be engaged while switch position is in the OFF position?

Answer 19

By engaging the autopilot

Question 20

When do the Anti-float tabs begin movement?

Answer 20

-As the stabilizer (trim) passes through 10* nose up

Question 21

When does the throw limiter begin to operate and also end?

Answer 21

On acceleration- begins to restrict at 200 KIAS and is fully restricted by approx 300 KIAS

On deceleration- fully unrestricted by 160-170 KIAS

Question 22

At what hydraulic pressure will the rudder automatically revert to manual

Answer 22

Approx 1000 psi

Question 23

When will the auto slats extend? What indications will you see? When will they retract?

Answer 23

During an impending stall:

• slats are in mid position
• airspeed 240 KIAS or less

Slats will automatically extend to extended position. Once condition ceases to exist, slats will retract to mid.

DISAG and AUTO lights illuminate

Question 24

What are the different Yaw Damp switch positions?

Answer 24

OFF= Is off unless autopilot is engaged, then Yaw Damp is ON

ON= Yaw Damp is on

OVRD= Yaw Damp is always off

Question 25

What does the Elevator Augmentation system do?

Answer 25

When the control tab is displaced upward beyond a preset limit (attempting to pitch the nose down), hydraulic power moves the elevator surface downward to assure a positive nose down pitch control (stall recovery)

Question 26

Do we still have operation of the Elevator augmentation system with the left hydraulic system inop?

Answer 26

Yes, 2 full down cycles (pushes) from the accumulator

Question 27

What do Geared tabs do?

Answer 27

Mechanically connected to the stabilizer, so when the elevator moves, the geared tab is forced in the opposite direction (same direction as the control tab) thus assisting the control tab.

Question 28

What is the order of priority for the stabilizer trim?

Answer 28

• Primary trim handles (suitcase handles)
• Primary trim switches (control wheel)
• Alternate trim (chiclets)
