FLIGHT CONTROLS

Question 1

What power the yaw dampers?

Answer 1

L and C hydraulics

Question 2

where does the yaw dampers takes is inputs from? (2)

Answer 2

both ADCs and

all 3 IRUs

Question 3

When is the speedbrakes is armed for landing? (3)

Answer 3

Hyd press to both truck tilt actuators and
LG on the ground (no tilt sense) and
both thrust levers at idle

Question 4

SPEEDBRAKES EXT caution light on when? (2)

Answer 4

Flaps in landing position (25/30) or
Captain’s RA is at/or 800ft
Openskies limitation is 1000ft AGL
caution inhibited below 15ft RA

Question 5

if L HYD PRESS lost, why don’t we arm the speedbrakes in auto?

Answer 5

HYD press to the gear truck tilt actuators is lost. there is no way to know if and when the truck will sense a no tilt condition which would cause an auto-deployment and that would compromise safety when in flight

Question 6

When does the speedbrakes automatically deploy during RTO? (4)

Answer 6

Hyd press to both truck tilt actuators and
LG on the ground (no tilt sense) and
both thrust lever at idle and
either reverse thrust lever moved reverse idle
openskies: RTO, speedbrake in manual before reverse

Question 7

What does rudder ratio does?

Answer 7

rudder ratio dampens pilots inputs to the rudder

30° up to 127Kts to 3.5° at 410Kts

Question 8

components of the rudder ratio?

Answer 8

use both ADCs
2 rudder ratio changer modules
a single actuator (L hyd system)

Question 9

RUDDER RATIO light means?

Answer 9

above 160Kts: avoid large or abrupt rudder inputs
if normal L hyd press: -XWIND 15Kts
-do not autoland
AP up to 180ft ARTE

Question 10

What system power the stabilizer trim?

Answer 10

Center and Right Hyd system

Question 11

stabilizer trim on AP?

Answer 11

AP uses only 1 trim module

trimming at half the manual trim rate

Question 12

STAB TRIM lights means?

Answer 12

one or more trim brakes has failed to release

Question 13

SPOILERS light means?

Answer 13

one or more spoiler pairs are inoperative

Question 14

The amber LEADING EDGE light illuminated indicates?

Answer 14

Slat position disagree, or

slat assymmetry

Question 15

When is the flap load relief system armed?

Answer 15

When flaps 30 has been selected with the flap lever

Question 16

The flight control shutoff switches control hydraulic power to? (3)

Answer 16

stabilizer, elevators and rudder

Question 17

Which hydraulic system powers the rudder ratio changer?

Answer 17

Left
the ratio changer receives air data computer airspeed inputs and provides control signals to an actuator powered by the left hydraulic system

Question 18

Automatic stabilizer trim uses?

Answer 18

One trim control module at half electric or alternate trim rate

Question 19

When multiple AP are engaged, electric trimming is?

Answer 19

Inhibited

on single AP, electric trimming causes AP to disengage

Question 20

Speedbrakes ARMED. What is NOT required for auto extension on landing?

Answer 20

Reverse thrust lever raised to its interlock stop
auto extension requires hydraulic pressure to both lg truck tilt actuators, both truck tilt sensors detect no-tilt and both thrust levers at idle.
speedbrake will also extend automatically whenever these 3 conditions occur and either reverse thrust lever is raised to its interlock stop and the speedbrake lever does not need to be ARMED

Question 21

When do slats normally move from the TO to the landing position?

Answer 21

when the flap lever is moved to position 25

Question 22

When do slats move from the TO to the landing position in ALTN?

Answer 22

When flaps 20 is selected using the alternate selector switch

Question 23

When is FLAP LD RELIEF advisory message is displayed?

Answer 23

Flap load relief system fails to operate when required

Question 24

How many hydraulic actuators are used for each aileron?

Answer 24

2
rotating either control wheel sends a signal to the aileron hydraulic actuators.
2 actuators are used for each aileron

Question 25

Pressing either alternate flaps switch?

Answer 25

Shuts off hydraulic power to the flap and slat drive systems

Question 26

a RUDDER RATIO advisory message apperas on EICAS?

Answer 26

the L hydraulic system actuator is automatically depressurized

Question 27

What powers the elevator feel systems?

Answer 27

Center and Right hydraulics

mechanical springs provide feel following a loss of center and right hudraulic

Question 28

How many spoiler panels are there on each upper wing surface?

Answer 28

6

Question 29

During flaps/slats alternate operation, which protection is provided?

Answer 29

Slat asymmetry protection only

Question 30

the amber TRAILING EDGE light illuminated indicates?

Answer 30

Flap position disagree, or
flap asymmetry, or
flap load relief failure

Question 31

Flap maneuvering speeds allow for?

Answer 31

25 degrees bank plus additional 15 degree bank safety factor before initial buffet is encountered
