B. can be easily removed without the use of tools.
C. is visible to the visual observer or other crewmembers.
A. does not adversely affect the center of gravity.
As speed increases, induced drag will?
A. Increase
B. Decrease
C. Remain constant
B. Decrease
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?
30 = 1.154
A. 47 pounds.
B. 34 pounds.
C. 38 pounds.
C. 38 pounds.
In a fixed-wing aircraft, yaw is controlled by?
A. the stabilizer.
B. the ailerons.
C. the rudder.
C. the rudder.
As temperature decreases, aircraft performance will?
A. Remain Constant
B. Decrease.
C. Increase.
C. Increase.
Which of the following increases load factor the most on fixed wing aircraft?
A. Steady climb.
B. Unpowered stall.
C. Level turn.
C. Level turn.
During an approach to a stall, an increased load factor will cause the aircraft to?
A.have a tendency to spin.
B.stall at a higher airspeed.
C. be more difficult to control.
B.stall at a higher airspeed.
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?
A. exceeds its critical angle of attack.
B. exceeds maximum allowable operating weight.
C. exceeds the maximum speed.
A. exceeds its critical angle of attack.
The angle of attack at which an airplane wing stalls will?
A. remain the same regardless of gross weight.
B. increase if the CG is moved forward.
C. change with an increase in gross weight.
A. remain the same regardless of gross weight.
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?
A. a longer takeoff run.
B. difficulty in recovering from a stalled condition.
C. stalling at higher-than-normal airspeed.
B. difficulty in recovering from a stalled condition.
When operating an unmanned airplane, the remote pilot should consider that the load factor on the wings may be increased anytime?
A. the airplane is subjected to maneuvers other than straight and level flight.
B. the CG is shifted rearward to the aft CG limit.
C. the gross weight is reduced.
A. the airplane is subjected to maneuvers other than straight and level flight.
The term “angle of attack” is defined as the angle between the?
A. airplane’s longitudinal axis and that of the air striking the airfoil.
B. airplane’s center line and the relative wind.
C. chord line of the wing and the relative wind.
C. chord line of the wing and the relative wind.
At which bank angle does the load factor increase dramatically?
A. 45-50 degrees.
B. 15 degrees.
C. 30 degrees.
A. 45-50 degrees.
As the angle of attack increases, induced drag will?
A. Remain the same.
B. Increase.
C. Decrease.
B. Increase.
What could be a consequence of operating a small unmanned aircraft above its maximum allowable weight?
A. Shorter endurance.
B. Faster speed.
C. Increased maneuverability.
A. Shorter endurance.
