ASA Chapter 1 ppl
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 turn
4-5-6 because the bank is increased too rapidly during the early part of the turn
When departing behind a heavy aircraft, the pilot should avoid wake turbulence by maneuvering the aircraft
Above and upwind the heavy aircraft.
When landing behind a large aircraft, the pilot should avoid wake turbulence by staying
Above the large aircraft's final path and landing beyond the large aircrafts touchdown point.
Which of the following statements relates to Bernoulli's principle
Air traveling faster over a curved upper surface of an airfoil causes lower pressure on the top of the surface
Ground effect is most likely to result in which problem?
Becoming airborne before reaching recommended takeoff speed.
during a spin to the left, which wings are stalled
Both wings are stalled
When are the four forces that act on an airplane in equilibrium?
During unaccelerated flight
What determines the longitudinal stability of an airplane?
Location of CG with respect to the center of lift
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 in the flightpath of aircraft operating below the aircraft generating the turbulence
When landing behind a large aircraft, which procedure should be followed for vortex avoidance?
Stay above it's final approach flightpath all the way to touchdown
The four flight fundamentals involved in maneuvering an aircraft
Straight and level flight, turns, climbs, and descents
The term angle of attack is defined as
The angle between the wing chord line and the relative wind.
What causes an airplane to pitch nose down 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
What is ground effect?
The result of the interference of the surface of the Earth with the airflow patterns about an airplane.
What is the purpose of a rudder on an airplane ?
To control yaw.
What is the purpose of wing flaps?
To enable the pilot to make steeper approaches to a landing without increasing the airspeed.
Changes in the center of pressure of a wing affect the aircraft's
aerodynamic balance and controllability
In flying the rectangular course, when would the aircraft be turned less than 90 degrees?
corners 1 and 4
Wingtip vortices are created only when an aircraft is
developing lift
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
difficulty recovering from a stalled condition
If an emergency situation requires a downwind landing, pilots should expect a faster
ground speed at touchdown, a longer ground roll, and a likelihood of overshooting the desired touchdown point
The greatest vortex strength occurs when the generating aircraft is
heavy, clean, and slow
What force makes an airplane turn?
horizontal lift component
One of the main functions of flaps during approach and landing is to
increase angle of descent without increasing airspeed
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
Loading an airplane to the most aft CG will cause the airplane to be
less stable at all speeds
Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at
less than the length of the wingspan above the surface
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
The four forces acting on an airplane in flight are
lift, weight, thrust, and drag
The wind condition that requires maximum caution when avoiding wake turbulence on landing is a
light quartering tailwind
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 spot.
How does the wake turbulence vortex circulate around each wing tip
outward, upward and around each tip
As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will
remain the same regardless of altitude
The angle of attack at which an airplane wing stalls will
remain the same regardless of gross weight
An airplane said to be inherently stable will
require less effort to control
Wingtip vortices created by large aircraft tend to
sink below the aircraft generating turbulence
The amount of excess load that can be imposed on the wing of an airplane depends upon the
speed of an airplane
in what flight condition must and aircraft be placed in order to spin?
stalled
During an approach to a stall and increased load factor will cause the airplane to
to stall at a higher airspeed
Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?
turns
