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.
(Refer to Figure 66.) While practicing S-turns, a consistently smaller half-circle is made on one side of the road than the other, and this turn is not completed before crossing the road or reference line, This would most likely occur in turn
4-5-6 because the bank is increased too rapidly during the early part of the turn.
If an emergency situation requires a downwind landing, pilots should expect a faster
groundspeed at touchdown, a longer ground roll, and the likelihood of overshooting the desired touchdown point.
When executing an emergency approach to land in a single-engine airplane, it is important to maintain a constant glide speed because variations in glide speed
nullify all attempts at accuracy in judgement of gliding distance and landing spots.
During a spin to the left, which wing(s) is/are stalled?
Both wing are stalled.
The angle of attack at which an airplane wing stalls will
remain the same regardless of gross weight.
What must a pilot be aware of as a result of ground effect?
Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating.
Which landing behind a large aircraft, which procedure should be followed for vortex avoidance?
Stay above its final approach flightpath all the way down to touchdown.
How does the wake turbulence vortex circulate around each wingtip?
Outward, upward, and around each tip.
When taking off or landing at an airport where heavy aircraft are operating, one should be particularly alert to the hazards of wingtip vortices because this turbulence tends to
sink into the flightpath of an aircraft operating below the aircraft generating turbulence.
Wingtip vortices are created only when an aircraft is
developing lift.
The greatest vortex strength occurs when the generating aircraft is
heavy, clean, and slow.
Wingtip vortices created by large aircraft tend to
sink below the aircraft generating turbulence.
The wind condition that requires maximum caution when avoiding wake turbulence on a landing is a
light, quartering headwind.
When landing behind a large aircraft, the pilot should avoid wake turbulence by staying
above the large aircraft’s final approach path and landing beyond the large aircraft’s touchdown point.
When departing behind a heavy aircraft, the pilot should avoid wake turbulence by maneuvering the aircraft
above and upwind from the heavy aircraft
