Interior A/C

Question 1

What are the primary flight controls

Answer 1

Elevator, rudders, ailerons

Question 2

Explain the purpose of the elevator

Answer 2

Controlled by Yolk (Pull/Push)
Used for Pitch

Question 3

Explain the purpose of an aileron

Answer 3

Controlled by Yolk (side/side)
Used for Roll/Bank

Question 4

Explain the use of rudder

Answer 4

Controlled by rudders (2 pedals)
Used for Yaw

Question 5

Trim

Answer 5

Small control surface attached at the trailing edge of a primary control surface

Question 6

What is trim used for

Answer 6

• uses airflow to apply force in opposite direction
• neutralize/reduce pressure
• relieves sloppy control and pilot fatigue
• UP: NOSE UP, ELEVATOR UP, TAIL DOWN
• DOWN: NOSE DOWN, ELEVATOR DOWN, TAIL UP

Question 7

Flaps

Answer 7

Attached to trailing edge of wings between fuselage and ailerons

Question 8

What is the purpose of flaps?

Answer 8

• Increase lift, increase drag, decrease stalling speed
• T/O & Land at slower speeds and shorter distance
• to descend or reduce speed
• allow a steeper descend rate and angle w/o increase in speed
• change curvature of wing
• changes speed of stall (w/ full flaps = 40 KTS, w/o = 48 KTS)
• reduces t/o ground roll
• reduces total distance to clear an obstacle by 10%
