|
How are flight control surfaces controlled?
|
These surfaces are controlled by various computers and hydraulic servo-cylinders installed throughout the aircraft.
|
|
|
What are the flight control surfaces on the aircraft?
|
- Ailerons
- LEF - TEF - Stabilizers - Rudders - Speed Brake |
|
|
What do ailerons provide in flight?
|
The ailerons are commanded asymmetrically to produce roll motion.
|
|
|
What do ailerons provide during takeoff or landing?
|
(With flaps switch set to half or full) They deflect symmetrically with the TEF up to 42 degrees.
|
|
|
The hinged rear portion of an aircraft wing moved differently on each side of the aircraft to obtain _______ or _______ moments.
|
Lateral or Roll moments
|
|
|
Where are ailerons located?
|
On the outboard trailing edge of each wing.
|
|
|
What do LEF provide in flight?
|
They deflect asymmetrically to aid the ailerons in producing roll motion.
|
|
|
What do LEF provide during take off or landing?
|
The LEF deflect symmetrically to change lift.
|
|
|
Where are the LEF located?
|
On the inboard and outboard leading edge of each wing.
|
|
|
What do TEF provide during in flight?
|
They independently deflect asymmetrically to aid the ailerons in producing roll motion.
|
|
|
What do TEF provide during take off or landing?
|
They deflect symmetrically to change lift.
|
|
|
Where are TEF located?
|
On the trailing edge of each wing.
|
|
|
What do stabilizers provide?
|
- They deflect symmetrically to produce pitch motion.
- Asymmetrically to produce roll motion. |
|
|
Where are stabilizers located?
|
On either side of the tail of the aircraft.
|
|
|
What do Rudders provide during takeoff or landing?
|
- When AOA is less than 8 degrees, the rudders toe-in to increase lift and improve stability.
- When AOA is more than 9 degrees the rudders toe-out to improve stability. |
|
|
What do Rudders provide during in flight?
|
They are commanded symmetrically to produce yaw motion.
|
|
|
Where are Rudders located?
|
On the rear of each vertical stabilizer.
|
|
|
What is the purpose of the Speed Brake?
|
Under certain conditions, the speed brake may be extended into the air stream creating drage and slowing the aircraft's airspeed.
|
|
|
Which aircrafts are equipped with Speed Brakes?
|
F/A-18 A-D
|
|
|
Where is the speed brake located?
|
On top of the aft fuselage between the vertical stabilizers.
