How will frost on the wings of an airplane affect takeoff performance?
A) Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability.
B) Frost will change the camber of the wing, increasing its lifting capability.
C) Frost will cause the airplane to become airborne with a higher angle of attack, decreasing the stall speed.

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.

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.

What determines the longitudinal stability of an airplane?
A) The location of the CG with respect to the center of lift.
B) The effectiveness of the horizontal stabilizer, rudder, and rudder trim tab.
C) The relationship of thrust and lift to weight and drag.
