Questions With Verified Answers
What determines the longitudinal stability of an airplane? - Correct-answer-The
location of the CG with respect to the center of lift.
Which device is a secondary flight control? - Correct-answer-flaps, trim tabs,
leading edge devices, spoilers
What causes an airplane (except a T-tail) to pitch nosedown when power is
reduced and controls are not adjusted? - Correct-answer-The downwash on the
elevators from the propeller slipstream is reduced and elevator effectiveness is
reduced.
Floating caused by the phenomenon of ground effect will be most realized during
an approach to land when at - Correct-answer-less than the length of the
wingspan above the surface

In what flight condition must an aircraft be placed in order to spin? - Correct-
answer-Stalled
During a spin to the left, which wing(s) is/are stalled? - Correct-answer-Both
wings are stalled
Why is frost considered hazardous to flight? - Correct-answer-Frost spoils the
smooth flow of air over the wings, thereby decreasing lifting capability
The term "angle of attack" is defined as the angle - Correct-answer-between the
wing chord line and the relative wind
Which of the following is true concerning flaps? - Correct-answer-Flaps allow an
increase in the angle of descent without increasing airspeed.
What is the relationship of lift, drag, thrust, and weight when the airplane is in
straight-and-level flight? - Correct-answer-Lift equals weight and thrust equals
drag
