Q

During a spin to the left, which wing(s) is/are stalled?

A

Both wings are stalled

21
Q

What is ground effect?

A

The result of the interference of the surface of the Earth with the airflow patterns about an airplane

22
Q

Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at?

A

Less than the length of the wingspan above the surface

23
Q

What must a pilot be aware of as a result of ground effect?

A

Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating

24
Q

An aircraft leaving ground effect during takeoff will

A

experience an increase in induced drag and a decrease in performance

25
Ground effect is most likely to result in which problem?
Becoming airborne before reaching recommended takeoff speed
26
What force makes an airplane turn?
The horizontal component of lift
27
What determines the longitudinal stability of an airplane?
the location of the CG with respect to the center of lift
28
An airplane said to be inherently stable will
require less effort to control
29
Changes in the center of pressure of a wing affect the aircraft's
aerodynamic balance and controllability
30
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 in recovering from a stalled condition
31
What causes an airplane (expect a T-tail) to pitch nosedown when power is reduced and controls are no adjusted?
The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced
32
What is the effect of advancing the throttle in flight?
Both aircraft groundspeed and angle of attack will increase
33
Loading an airplane to the most aft CG will cause the airplane to be
less stable at all speeds
34
An airplane loaded with the Center of Gravity (CG) rear of the aft CG limit could
increase the likelihood of inadvertent overstress.
35
In what flight condition are torque effects more pronounced in a single-engine airplane?
Low airspeed, high power, high angle of attack
36
The left turning tendency of an airplane caused by P-factor is the result of the
propeller blade descending on the right producing more thrust than the ascending
37
When does P-factor causes the airplane to yaw to the left
When at high angles of attack
38
Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?
Turns
39
(Refer to Figure 2 below.) If an airplane weights 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
40
(Refer to Figure 2 below.) If an airplane weights 2,300 pounds, what approximate weight would the airplane structure be required to support during a 60 Deg banked turn while maintaining altitude?
4,600 pounds
41
(Refer to Figure 2 below.) If an airplane weights 4,500 pounds, what approximate weight would the airplane structure be required to support during a 45 deg banked turn while maintaining altitude
6,750 pounds
42
The amount of excess load that can be imposed on the wing of an airplane depends upon the?
speed of the airplane
43
During an approach to a stall, an increased load factor will cause the aircraft to
stall at a higher airspeed
44
structural damage or failure is more likely to occur in smooth air at speeds above
Vne
45
Limit load factor is the ratio of
Maximum sustainable load to the gross weight of the airplane
46
(Refer to Figure 72 below.) A positive load factor of 2 at 80 mph would cause the airplane to
stall
47
(Refer to Figure 72 below.) What load factor would be created if positive 15 feet per second gusts were encountered at 120 mph?
2.0
48
(refer to Figure 72 beow.) The airspeed indicated by points A and J is
normal stall speed
