Flight Controls Flashcards
T/F: The Spoiler switches on the Flight Control Panel are for maintenance purposes only
True
What is manual reversion with regards to the ailerons or elevator?
With a loss of hydraulic systems A and B, the ailerons or elevator can still be mechanically positioned by the pilot’s control wheel. (Control forces are higher due to friction and aerodynamic loads).
T/F: You can use aileron trim with the auto pilot engaged
False. This is prohibited
How many spoilers does the aircraft have and how are they powered?
10 spoilers - 8 flight spoilers & 2 ground spoilers. Powered only by hydraulics (no manual reversion). Hydraulic A powers the ground spoilers & 2 flight spoilers on each wing. Hydraulic B powers 2 flight spoilers on each wing.
The flight spoilers deploy symmetrically when the Speedbrake Lever is used beyond the _______ position.
ARMED
What is the purpose of the Aileron Transfer Mechanism?
The purpose of the aileron transfer mechanism is to isolate the aileron system from the flight spoilers if a jam occurs.
When does the FEEL DIFF PRESS light illuminate?
When either hydraulic system or elevator feel pitot system fails, excessive differential pressure is sensed in the elevator feel computer.
What is the purpose of the Stabilizer Trim Cutout Switch?
This switch deactivates stabilizer trim anytime the direction of trim is opposite of pressure on the control column.
T/F: Rudder trim is not available when the rudder trim indicator is inoperative
False.
The yaw damper system consists of a _____ and _______ yaw damper.
main, standby
During normal operations, the main yaw damper uses hydraulic system _________
B
T/F: The yaw dampener can still be used with the loss of Hydraulics A&B via the standby hydraulic system
True
The Mach Trim system automatically engages above Mach _____
.615
The Horizontal Stabilizer can be controlled in what three ways?
- Manually - stabilizer trim wheels (actuates stabilizer via cables)
- Electrically - trim switches on control wheel (actuates stabilizer via electric trim motor)
- Automatic (autopilot)
Compression of the _______ main landing gear strut enables the ground spoilers to deploy
Right. (The flight spoilers will deploy via compression of either one of the struts)
On the ground, the SPEED BRAKES EXTENDED light illuminates when the SPEED BRAKE lever is in the ________ detent and the ground spoilers are not stowed.
DOWN
What kind of Flaps does the aircraft have?
Double Slotted flaps
The TE flaps are mechanically controlled by the FLAP Lever and are normally operated by ______________
hydraulic system B.
Each wing has ____ leading edge flaps inboard and _____ slats outboard of each engine.
2, 4
T/F: The LE flaps are either up, in transit, or fully extended while the LE slats have an intermediate extended position
True
T/F: At flap positions 1, 2, and 5 an autoslat function is available that moves the LE slats to full extended if the airplane approaches a stall condition.
True
T/F: Flap load relief is operative at all flap positions
False. It is only available at Flaps 30 or 40
T/F: Flap asymmetry conditions can only be corrected on the ground.
True
T/F: Leading edge slats 1 & 8 are not monitored for skew conditions
True
