PRIVATE PILOT GLIDER ACTUAL EXAM
QUESTIONS AND CORRECT ANSWERS
COMPLETE TEST PAPER
●● How does Bernoulli's principle relate to the design of an aircraft
wing?
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
●● 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 during
takeoff?
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
