Flight Controls Flashcards
Do not deploy speed brakes below
1000 feet AGL
Can either hydraulic system provide full power to the ailerons
yes
with total hydraulic failure how are the ailerons operated?
reverts to mechanical control
with jammed spoilers what can supply roll control through the ailerons?
force supplied to the CA control wheel provides roll control through the ailerons
with jammed ailerons what can supply roll control through the spoilers?
force supplied to the FO control wheel provides roll control through the spoilers
Is it permissible to add aileron trim with the AP engaged?
Prohibited, may cause abrupt rolling moment
Spoilers deploy when how much bank is entered?
10° they deploy with the ailerons and remain flat on the down side
To reposition the aileron trim to neutral
movement of both switches
The elevator is ____ powered
The stabilizer is _____ powered
hydraulically
electrically
How is a control jam over ridden?
Over ride mechanism allows the control column to be physically separated
The FEEL DIFF PRESS light indicates
excessive differential hydraulic pressure is sensed in the elevator feel computer
how does the Mach Trim system engage and disengage?
Automatically as a function of airspeed
When MACH TRIM FAIL is illuminated only when the master caution annunciator recall is activated it means
a single channel has failed in the mach trim system
The Elevator Feel Shift Module increase hydraulic system A pressure to the elevator feel and centering unit during a stall for what purpose?
To increase the forward control column force to approximately double the normal feel pressure to try to assist in not stalling the plane
There are two mode on the main electric and autopilot stabilizer trim,
high speed flaps extended
low speed flap retracted
if the autopilot is engaged actuating either pair of stabilizer trim switches
disengages the autopilot
if takeoff is attempted with the stabilizer trim outside the take off limits what can one expect
a intermittent horn, (takeoff config horn)
If manual trim is used to trim beyond the electrical trim limits can the stab trim be used to return it to normal limits
yes
The stab trim main electric cutout switch and the stab trim autopilot cutout switch are provided to allow the autopilot or main electrical trim input to be
disconnected from the single stab trim motor
when the control column movement opposes the trim direction what will occur?
The control column actuated stabilizer trim cutout switches stop operation to the main electric and autopilot trim.
Switching the Stab trim into OVERRIDE
the electric trim can be used regardless of control column position
the speed trim system is a speed stability augmentation system designed to improve the flight characteristics during any operation
Low gross weight, aft CG, and high thrust when the autopilot is not engaged
Both hydraulic systems operate the rudder
including the standby
What hydraulic system is the yaw dampener associated with?
system B and the standby system
135 knots and above the hydraulic pressure is reduced to limit the rudder authority
it provides the controls necessary for the stages of flight.
Using the rudder pedals for steering how much displacement is capable?
7° either side of center
when the speed brake lever is actuated on the ground or in the air
ground all spoilers deploy
air on the in flight spoilers
which hydraulic system powers the ground spoilers
A
if spoilers are deployed in a turn
the rate of roll increases greatly
All spoilers will automatically deploy to full on landing if
the speed brake lever is armed and
the thrust lever are in idle
SPEEDBRAKE DO NOT ARM light indicates
abnormal condition or wheel speed is below 60 knots and the speed brake lever is not in the down position.
Whats the difference between Flight Detent and Up on the spoiler lever
Flight Detent full spoiler deployment in the air
Up all flight and ground full spoilers deployment on the ground
Can the Trailing edge flaps be operated with full hydraulic failure?
Yes, electrically
is there asymmetrical or skew protection of the trailing edge flaps electrically?
No
The Flaps Slats Electrical Unit (FSEU) monitor trailing flap to
Monitor asymmetry or skewing. It closes the trailing edge bypass valve if it senses it.
The Trailing Edge (TE) flap load relief protects the flaps from excessive loads
When the flaps are at 40 and excessive AS exceeds a predetermined limit it retracts the flaps to 30
What are the flap gates for at 1 and 15?
Single Engine and Normal Go around
Where would one find the TE flap asymmetry indications?
Back overhead panel, Flap Position Indicator
LE devices are normally extended and retracted by
Hydraulic system B
Can the LE devices be retracted in Standby
No
flaps 1 the Auto Slat system automatically drive the slats to FULL EXTENDED as the plane approaches
a stall condition
Amber light LE FLAP TRANSIT indicates
LE slat skew condition exist
LE device in transit or out of position with its trailing edge devices
