For Question 1 select "B", "C" or "D" ("A" is selected only as an example)!
1. The four forces acting on an airplane in flight are:
A) None of the below. B) lift, weight, gravity, and thrust. C) lift, gravity, power, and friction. D) lift, weight, thrust, and drag.
2. 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. D) All of the above.
3. Which basic flight maneuver increases the load factor on an airplane as compared to straight and level:
A) Climbs. B) Turns. C) Stalls. D) None of the above.
4. During an approach to a stall, an increased load factor will cause the airplane to:

5. The angle of attack at which an airplane wing stalls will:
A) increase if the CG is moved forward. B) change with an increase in gross weight. C) remain the same regardless of gross weight. D) None of the above.
6. (Refer to Figure 2 below.) If an airplane weights 2,300 pounds, what approximate weight would the airplane structure be required to support during a 60 degree banked turn while maintaing altitude?
A) 2,300 pounds. B) 3,400 pounds. C) 4,600 pounds. D) None of the above.
7. (Refer to Figure 1 below.) The acute angle A is the angle of:
A) incidence. B) attack. C) dihedral. D) None of the above.
8. 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 degrees in advance of the point the force was applied. D) All of the above.
9. What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight?

10. When are the four forces that act on an airplane in equilibrium?
