ASA Private Pilot 2020 Test Prep Chapter 1 Questions Flashcards
(Refer to Figure 1.) The acute angle A is the angle of
attack.
The term “angle of attack” is defined as the angle
between the chord line and the relative wind.
The angle between the chord line of an airfoil and the relative wind is know as the angle of
attack.
The term “angle of attack” is defined as the angle between the
chord line of the wind and the relative wind.
Which statements relates to Bernoulli’s principle?
Air travelling 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
lift, weight, thrust, and drag.
What is the purpose of rudder on an airplane?
To control yaw.
What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight?
Lift equals weight and thrust equals drag.
When are the four forces that act on an airplane in equilibrium?
During unaccelerated flight.
An airplane said to be inherently stable will
require less effort to control.
What determines the longitudinal stability of an airplane?
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?
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 the airplane would be
difficulty in recovering from a stalled condition.
Loading an airplane to the most aft CG will caused the airplane to be
less stable at all speeds.
Changes in the center of pressure of a wing affects the aircraft’s
aerodynamic balance and controllability.
(Refer to Figure 2.) If an airplane weighs 2,300 pounds, what approximate weight would the airplane structure be required to support during at 60 degree banked turn to maintain altitude?
4,600 pounds.
(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?
3,960 pounds.
(Refer to Figure 2.) If an airplane weighs 4,500 pounds, what approximate weight would the structure be required to support during a 45 degree banked turn while maintaining altitude?
6,750 pounds.
The amount of excess load that can be imposed on the wing of an airplane depends upon the
speed of the airplane.
Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?
Turns.
What force makes an airplane turn?
The horizontal component of lift.
During an approach to a stall, an increased load factor will cause the airplane to
stall at a higher airspeed.
Select the four flight fundamentals involved in maneuvering an aircraft.
Straight-and-level flight, turns, climbs, and descents.
(Refer to Figure 62.) In flying the rectangular course, when would the aircraft be turned less than 90 degrees?
Corners 1 and 4.
