Flight Controls

Question 1

Adverse yaw

Answer 1

During banking, high wing more lift and drag, causing slow down
Pronounced at low airspeed

Question 2

Reduce adverse yaw

Answer 2

Differential aileron
Frise-type aileron
Coupled ailerons and rudder
Flaperons

Question 3

T tail

Answer 3

1. Above downwash from wing and prop
2. Reduce noise and vibration
3. Move greater distance to raise nose, greater force
4. Moment arm causes high loads, create flutter
5. Susceptible to deep stall

Question 4

Stabilator

Answer 4

Uses a riser antiservo to reduce sensitivity

Question 5

Canard

Answer 5

Creates lift, nose up, less drag

Question 6

Types of flaps

Answer 6

Plain
Split
Slotted
Fowler

Question 7

Slotted fowler

Answer 7

Increase lift coefficient
When lowered, high energy air from lower surface through slot to upper.
Accelerates upper boundary layer
Delays airflow separation

Question 8

Leading edge devices

Answer 8

Fixed slots
Movable slats
Leading edge flaps
Leading edge cuffs

Question 9

Trim systems

Answer 9

Trim tabs
Balance tabs
Servo tabs
Antiservo tabs
Ground adjustable tabs
Adjustable stabilizer
