Private Pilot Glider Written Exam Complete Questions and Answers!

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 - ANSWER Groundspeed at touchdown, a longer ground roll, and the likelihood of overshooting the desired touchdown point. As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will - ANSWER remain the same regardless of altitude. In what flight condition must an aircraft be placed in order to spin - ANSWER Stalled During a spin to the left, which wing(s) is/are stalled - ANSWER Both wings are stalled The angle of attack at which an airplane wing stalls will - ANSWER Remain the same regardless of gross weight One of the main functions of flaps during approach and landing is to - ANSWER Increase the angle of descent without increasing the airspeed What is one purpose of wing flaps? - ANSWER To enable the pilot to make steeper approaches to a landing without increasing the airspeed. Ground effect is most likely to result in which problem? - ANSWER Becoming airborne before reaching the recommended takeoff speed What is ground effect? - ANSWER The result of the interference of the surface of the Earth with the airflow patterns about an airplane Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at - ANSWER Less than the length of the wingspan above the surface What must a pilot be aware of as a result of ground effect? - ANSWER Induced drag decreases;t therefore, any excess speed at the point of flare may cause considerable floating
