Private Pilot Glider Written Exam Complete Questions and Answers!

The term "angle of attack" is defined as the angle - ANSWER Between the wing chord line and the relative wind. The angle between the chord line of an airfoil and the relative wind is known as the angle of. - ANSWER Attack Which statement relates to Bernoulli's principle? - ANSWER Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface The four forces acting on an airplane in flight are - ANSWER Lift, weight, thrust and drag When are the four forces that act on an airplane in equilibrium? - ANSWER During unaccelerated flight An airplane said to be inherently stable will - ANSWER Require less effort to control What determines the longitudinal stability of an airplane? - ANSWER The location of the CG with respect to the center of lift What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted? - ANSWER The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced 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 - ANSWER Difficulty in recovering from a stalled condition. Loading an airplane to the most aft CG will cause the airplane to be - ANSWER Less stable at all speeds Changes in the center of pressure of a wing affect the aircraft's - ANSWER Aerodynamic balance and controllability What force makes an airplane turn? - ANSWER The horizontal component of lift During an approach to a stall, an increased load factor will cause the airplane to - ANSWER Stall at a higher airspeed What four flight fundamentals are involved in maneuvering an aircraft? - ANSWER Straight and level flight, turns, climbs, and descents In flying the rectangular course when would the aircraft be turned less than 90 degrees? - ANSWER Corners 1 & 4 While practicing S-turns, a consistently smaller half circle is made on one side of the road than on the other, and this turn is not completed before crossing the road or reference line. This would most likely occur in - ANSWER 4-5-6 because the bank is increased too slowly during the latter part of the turn If an emergency situation requires a downwind landing, pilots should expect a faster -
