Chordline and relative wind

Correct Incorrect Correct answer

Pitch and the horizon

Correct Incorrect Correct answer

Wing and the airplane

Correct Incorrect Correct answer

Correct Incorrect Correct answer

2. Question

The turning tendency created from spiraling slipstream increases in magnitude with

More power and lower airspeeds

Correct Incorrect Correct answer

Less power

Correct Incorrect Correct answer

Greater pitch

Correct Incorrect Correct answer

Faster airspeed

Correct Incorrect Correct answer

3. Question

Which of the following are airfoils?

Wings

Correct Incorrect Correct answer

Propeller

Correct Incorrect Correct answer

Vertical Stabilizer

Correct Incorrect Correct answer

Ailerons

Correct Incorrect Correct answer

4. Question

What are the four forces of flight?

Lift, weight, thrust, drag

Correct Incorrect Correct answer

Lift, weight, speed, drag

Correct Incorrect Correct answer

Lift, thrust, resistance, weight

Correct Incorrect Correct answer

5. Question

In un-accelerated flight…

Drag is equal to thrust

Correct Incorrect Correct answer

Thrust is greater than drag

Correct Incorrect Correct answer

Lift is greater than weight

Correct Incorrect Correct answer

6. Question

An airfoil will stall when

It reaches critical angle of attack

Correct Incorrect Correct answer

You pitch up too much

Correct Incorrect Correct answer

You get too slow

Correct Incorrect Correct answer

It reaches angle of incidence

Correct Incorrect Correct answer

7. Question

The pitch of the aircraft is entirely responsible for whether it stalls or not.

False

Correct Incorrect Correct answer

True

Correct Incorrect Correct answer

8. Question

How does parasite drag relate to speed?

It increases as speed increases

Correct Incorrect Correct answer

It decreases as speed increases

Correct Incorrect Correct answer

9. Question

How does induced drag relate to speed?

It decreases as airspeed increases

Correct Incorrect Correct answer

It increases as airspeed increases

Correct Incorrect Correct answer

10. Question

Lift can be increased or decreased by

All of these

Correct Incorrect Correct answer

Changing angle of attack (AOA)

Correct Incorrect Correct answer

Changing wing shape (flaps, leading edge devices, etc)

Correct Incorrect Correct answer

Changing airspeed

Correct Incorrect Correct answer

11. Question

Ailerons are used to cause the airplane to

Roll

Correct Incorrect Correct answer

Yaw

Correct Incorrect Correct answer

Pitch

Correct Incorrect Correct answer

Swivel

Correct Incorrect Correct answer

12. Question

The rudder is used to cause the airplane to

Yaw

Correct Incorrect Correct answer

Roll

Correct Incorrect Correct answer

Pitch

Correct Incorrect Correct answer

The rudder is useless

Correct Incorrect Correct answer

13. Question

(Select all that apply) Adverse Yaw:

Is a yawing motion created by asymmetrical drag in a turn

Correct Incorrect Correct answer

Causes the nose to initally pivot toward the outside of the turn

Correct Incorrect Correct answer

Is not correctable

Correct Incorrect Correct answer

Is correctable with appropriate rudder use in the direction of the turn

Correct Incorrect Correct answer

14. Question

P-Factor:

Is a condition of asymmetric thrust caused by differing angles of attack on ascending and descending blades of the propeller

Correct Incorrect Correct answer

Always causes the nose to go left because the left side of the propeller spins faster

Correct Incorrect Correct answer

Is not correctable

Correct Incorrect Correct answer

15. Question

Select all that are, or can be, left turning tendencies

P-factor

Correct Incorrect Correct answer

Spiraling slipstream

Correct Incorrect Correct answer

Torque effect

Correct Incorrect Correct answer

Mach tuck

Correct Incorrect Correct answer
