Loading, Performance & Regulations
In a fixed-wing aircraft, pitch is controlled by
1 the ailerons.
2 the stabilizer.
3 the rudder.

As speed increases, induced drag will
1 Increase
2 Remain constant
3 Decrease

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
1 stalling at higher-than-normal airspeed.
2 difficulty in recovering from a stalled condition.
3 a longer takeoff run.
difficulty in recovering from a stalled condition
A stall occurs when the smooth airflow over the unmanned airplane’s wing is disrupted and the lift degenerates rapidly. This is caused when the wing
1 exceeds the maximum speed.
2 exceeds maximum allowable operating weight.
3 exceeds its critical angle of attack.
exceeds its critical angle of attack.
What could be a consequence of operating a small unmanned aircraft above its maximum allowable weight?
1 Shorter endurance.
2 Faster speed.
3 Increased maneuverability.
Shorter endurance
When loading cameras or other equipment on an sUAS, mount the items in a manner that
1 is visible to the visual observer or other crewmembers.
2 can be easily removed without the use of tools.
3 does not adversely affect the center of gravity.
does not adversely affect the center of gravity.
If an unmanned airplane weighs 33 pounds, what approximate weight would the airplane structure be required to support during a 30° banked turn while maintaining altitude?
1 34 pounds.
2 47 pounds.
3 38 pounds.
38 pounds.
The term “angle of attack” is defined as the angle between the
1 chord line of the wing and the relative wind.
2 airplane’s longitudinal axis and that of the air striking the airfoil.
3 airplane’s center line and the relative wind.
chord line of the wing and the relative wind.
The angle of attack at which an airplane wing stalls will
1 increase if the CG is moved forward.
2 remain the same regardless of gross weight.
3 change with an increase in gross weight.
remain the same regardless of gross weight.
(Refer to FAA-CT-8080-2H, Figure 1.) The acute angle A is the angle of
1 incidence.

What effect does humidity have on flight performance?
1 It decreases performance.
2 It increases performance.
3 It has no effect over performance.
It decreases performance.
During an approach to a stall, an increased load factor will cause the aircraft to
1 have a tendency to spin.
2 stall at a higher airspeed.
3 be more difficult to control.
stall at a higher airspeed.
At which bank angle does the load factor increase dramatically
1 45-50 degrees.
2 30 degrees.
3 15 degrees.
45-50 degrees.
