PRIVATE PILOT TEST GUIDE (CHAPTER 3) QUESTIONS WITH EXPLANATIONS OF ANSWERS. “In what flight condition are torque effects more pronounced in a single-engine airplane? - CORRECT ANSWER Low airspeed, high power, high angle of attack." "The term "angle of attack" is defined as the angle between the - CORRECT ANSWER Chord line of the wing and the relative wind." "(Refer to Figure 2.) If an airplane weighs 3,300 pounds, what approximate weight would the airplane structure be required to support during a 30 degree banked turn while maintaining altitude? - CORRECT ANSWER 3,800 pounds" "Loading an airplane to the most aft CG will cause the airplane to be - CORRECT ANSWER Less stable at ALL speeds." "Ground effect is most likely to result in which problem? - CORRECT ANSWER Becoming airborne before reaching recommended takeoff speed." "Which statement relates to Bernoulli's principle? - CORRECT ANSWER Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface." "Changes in the center of pressure of a wing affect the aircraft's - CORRECT ANSWER Aerodynamic balance and controllability." "An airplane said to be inherently stable - CORRECT ANSWER Requires less effort to control." "The four forces acting on an airplane in flight - CORRECT ANSWER Lift, Weight, Thrust, Drag." "The left turning tendency of an airplane caused by P-factor is the result of the - CORRECT ANSWER Propeller blade descending on the right, producing more thrust than the ascending blade on the left." "What determines the longitudinal stability of an airplane? - CORRECT ANSWER The location of the Center of Gravity (CG) with respect to the center of lift." "When are the four forces that act on an airplane in equilibrium? - CORRECT ANSWER During unaccelerated flight." "When does P-factor cause the airplane to yaw to the left? - CORRECT ANSWER When at high angles of attack." "What causes an airplane (except a T-tail) to pitch nose down when power is reduced and controls are not adjusted? - CORRECT ANSWER The downwash on the elevator from the propeller slipstream is reduced and elevator effectiveness is reduced." "(Refer to Figure 1.) The acute angle A is the angle of - CORRECT ANSWER Attack." "(Refer to Figure 2.) If an airplane weighs 2,300 pounds, what approximate weight would the airplane structure be required to support during a 60 degree banked turn while maintaining altitude? - CORRECT ANSWER 4,600 pounds" "An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be - CORRECT ANSWER Difficulty in recovering from a stalled condition." "The angle between the chord line of an airfoil and the relative wind is known as the angle of - CORRECT ANSWER Attack." "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." "In what flight condition must an aircraft be placed in order to spin? - CORRECT ANSWER Stalled." "(Refer to Figure 2.) If an airplane weights 4,500 pounds, what approximate weight would the airplane structure be required to support during a 45 degree banked turn while maintaining altitude? - CORRECT ANSWER 6,400 pounds" "The amount of excess load that can be imposed on the wing of an airplane depends upon the - CORRECT ANSWER Speed of the airplane." "During a spin to the left, which wing(s) is/are stalled? - CORRECT ANSWER Both wings are stalled." "One of the main functions of flaps during approach and landing is to - CORRECT ANSWER Increase the angle of descent without increasing the airspeed." "Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight? - CORRECT ANSWER Turns" "What is one purpose of wing flaps? - CORRECT ANSWER To enable the pilot to make steeper approaches to a landing without increasing the airspeed." "What force makes an airplane turn? - CORRECT ANSWER The horizontal component of lift." "The angle of attack at which an airplane wing stalls - CORRECT ANSWER Remains the same regardless of gross weight." "During an approach to a stall, an increased load factor will cause the airplane to - CORRECT ANSWER Stall at a higher airspeed." "What is ground effect? - CORRECT ANSWER The result of the interference of the surface of the Earth with the airflow patterns about an airplane." "What are the four flight fundamentals that are involved in maneuvering an aircraft? - CORRECT ANSWER Straight-and-level flight, turns, climbs, and descents." "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." "What must a pilot be aware of as a result of ground effect? - CORRECT ANSWER Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating."
