1. The four forces acting on an airplane in flight are
A-- lift, weight, thrust and drag
B-- lift, weight, gravity and thrust
C-- lift, gravity, power and friction
2. One of the main functions of flaps during approach and landing is to
A-- decrease the angle of descent without increasing
B-- permit a touchdown at higher indicated
C-- increase the angle of descent without increasing
3. An ATC radar facility issues the following advisory to a pilot flying
north in a calm wind: "TRAFFIC 9 O'CLOCK, 2 MILES, SOUTHBOUND..."
Where should the pilot look for this traffic?
4. How does frost affect the lifting surfaces of an airplane on
A-- Frost may prevent the airplane from becoming
airborne at normal takeoff speed.
B-- Frost will change the camber of the wing,
increasing lift during takeoff.
C-- Frost may cause the airplane to become
airborne with a lower angle of attack at a lower
