Flight Controls

Question 1

(767) Stabilizer trim settings below 1.5 units requires:

Answer 1

The use of manual trim levers or alternate stabilizer trim

switches (as installed)

Question 2

The flight control columns and wheels are connected through jam override
mechanisms. If a jam occurs in a column or wheel, how can the pilots maintain
control?

Answer 2

The pilots can maintain control by applying force to the
other column or wheel to overcome the jam. When a
restricted portion of the flight controls are bypassed,
some control effectiveness may be lost

Question 3

What causes the SPEED BRAKES light to illuminate and the EICAS caution message
SPEEDBRAKES EXT to display?

Answer 3

Speedbrakes are extended when flaps are in a landing

position or radio altitude is 800 feet or below

Question 4

Alternate flap operation allows manual operation of the flaps and slats through
electric motors. Extension of the flaps and slats from UP to flaps 20 with the
alternate system requires approximately __________.

Answer 4

Two minutes

Question 5

(767) With Flaps 30 selected and airspeed increases above 170 knots, what action
should occur?

Answer 5

TE flaps will retract to 20

Question 6

(767) If an impending stall continues or pitch increases after both of the control
column shakers activate:

Answer 6

With the slats and flaps retracted, a control column

nudger/pusher will move the control columns forward

Question 7

(757) Upon receiving a signal from the stall warning system:

Answer 7

The slats automatically extend from the midrange
(takeoff) position to the fully extended landing position.
The slats retract a few seconds after the signal is
removed.

Question 8

If the UNSCHED STAB TRIM light illuminates and the EICAS caution message UNSCHD
STAB TRIM displays, what feature allows the pilot to quickly stop uncommanded trim
changes?

Answer 8

The control column can be used to interrupt stabilizer
trim commands. The stabilizer trim commands are
interrupted if the control column in displaced in the
opposing direction

Question 9

(767) When does the Pitch Enhancement System (PES) operate automatically?

Answer 9

Loss of left and center hydraulics

Question 10

(757) What occurs when either Alternate Flaps switch is pushed ON?

Answer 10

Hydraulic power is removed from both leading and

trailing edge drive systems

Question 11

When are the leading edge slats extended to the landing position during normal flap
extension?

Answer 11

Flaps 25

Question 12

When is Mach speed trim inhibited from trimming?

Answer 12

When electric, alternate, or autopilot trim is operating

Question 13

What is the purpose of the rudder ratio system?

Answer 13

As airspeed increases, the ratio changer desensitizes

inputs from the pilot to reduce the rudder deflection

Question 14

Which hydraulic system powers the rudder ratio system?

Answer 14

Left

Question 15

What are the limitations if a RUDDER RATIO light is illuminated and a RUDDER RATIO
EICAS message is displayed with normal left hydraulic system pressure?

Answer 15

Crosswind and autoland limitation must be observed

Question 16

What is the purpose of the yaw damper system?

Answer 16

Improves turn coordination and dutch roll damping

Question 17

What does the STAB TRIM light and EICAS message indicate?

Answer 17

Stabilizer trimming is at half the rate

Question 18

What does an UNSCHED STAB TRIM light and EICAS message indicate?

Answer 18

Uncommanded stabilizer movement

Question 19

When does an armed speedbrake lever move to the UP position and the spoiler
panels raise after landing occur?

Answer 19

Both thrust levers are at idle

Question 20

What is operated by the alternate flap/slat system?

Answer 20

Electric motors

Question 21

Why should the speed brake lever be moved from ARMED to the DOWN detent if
the AUTO SPDBRK light illuminate?

Answer 21

To prevent inadvertent speedbrake extension in flight

Question 22

Which of the following is true when the AUTO SPDBRK light is illuminated?

Answer 22

Speedbrakes can still be operated manually

Question 23

What is indicated by an illuminated SPOILERS light and SPOILERS EICAS message?

Answer 23

One or more spoiler pairs are inoperative

Question 24

(757) What does MACH SPD TRIM light indicate?

Answer 24

Mach speed trim system is inoperative

Question 25

(757) What type of stall protection is installed?

Answer 25

Autoslats; the leading edge slats automatically move
from the takeoff position to the landing position when
the stall warning system activates

Question 26

(757) If Flaps 30 is selected, what occurs if the flap load relief system is activated
above 162 knots?

Answer 26

Flaps retract to 25

Question 27

(757) What must be used to set stabilizer trim settings below three units?

Answer 27

The use of manual trim levers or alternate stabilizer trim

switches (as installed)

Question 28

(767) What is the stab trim rate when the Pitch Enhancement System (PES) is
operating?

Answer 28

0.25

Question 29

(767) How does the Pitch Enhancement System (PES) operate?

Answer 29

The PES uses a PTU driven by the right hydraulic system
which uses trapped left trim system fluid to power
stabilizer trim

Question 30

(767) What occurs when either Alternate Flaps switch is pushed ON?

Answer 30

Shuts off hydraulic power to selected flap or slat drive

unit(s)

Question 31

(767) What type of stall protection is installed?

Answer 31

Control column nudger/pusher

Question 32

(767) If Flaps 30 is selected, what occurs if the flap load relief system is activated
above 170 knots?

Answer 32

Flaps retract to 20

Question 33

(767) Shortly after selecting Flaps 1, a LE non‐normal occurs, what automatic action
will take place?

Answer 33

Hydraulic power to only the slats is automatically shut

off
