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.
