1.

The left turning tendency of an airplane caused by P-factor is the result of the A. clockwise rotation of the engine and the propeller turning the airplane counter-clockwise. B. propeller blade descending on the right, producing more thrust than the ascending blade on the left. C. gyroscopic forces applied to the rotating propeller blades acting 90° in advance of the point the force was applied.

2.	An airplane said to be inherently stable will A. be difficult to stall. B. require less effort to control. C. not spin.

3.	Angle of attack is defined as the angle between the chord line of an airfoil and the A. direction of the relative wind. B. pitch angle of an airfoil. C. rotor plane of rotation.

4.	The amount of excess load that can be imposed on the wing of an airplane depends upon the A. position of the CG. B. speed of the airplane. C. abruptness at which the load is applied.

5.

What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted? A. The CG shifts forward when thrust and drag are reduced. B. The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced. C. When thrust is reduced to less than weight, lift is also reduced and the wings can no longer support the weight.
