Part 107 Load Factor

What effect does high density altitude have on the efficiency of a UA propeller?

• Propeller efficiency is increased.

• Propeller efficiency is decreased.

• Density altitude does not affect propeller efficiency.

Answer explanation

As density altitude increases there are fewer molecules for the propeller to push against and propeller efficiency degreases.   The other 2 answers are incorrect because propeller efficiency decreases as density altitude increases.

To ensure that the unmanned aircraft center of gravity (CG) limits are not exceeded, follow the aircraft loading instructions specified in the

• Pilot's Operating Handbook or UAS Flight Manual.

• Aeronautical Information Manual (AIM).

• Aircraft Weight and Balance Handbook.

What could be a consequence of operating a small unmanned aircraft above its maximum allowable weight?

• Shorter endurance.

• Faster speed.

• Increased maneuverability.

According to 14 CFR part 107, who is responsible for determining the performance of a small unmanned aircraft?

• Owner or operator.

• Manufacturer.

• Remote pilot-in-command.

When operating an unmanned airplane, the remote pilot should consider that the load factor on the wings may be increased any time

• the CG is shifted rearward to the aft CG limit.

• the airplane is subjected to maneuvers other than straight-and-level flight.

• the gross weight is reduced.

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

• exceeds the maximum speed.

• exceeds maximum allowable operating weight.

• exceeds its critical angle of attack.

(Refer to Figure 2.) 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?

• 34 pounds.

• 47 pounds.

• 38 pounds.

How would high density altitude affect the performance of a small unmanned aircraft?

• Increased performance.

• Decreased performance.

• No change in performance.

Operating outside of the weight and balance limits of an unmanned aircraft

• can result in loss of control of the aircraft.

• increases performance.

• is not possible per aircraft design.

(Refer to Figure 2.) If an unmanned aircraft weighs 20 pounds, what approximate weight would the aircraft structure be required to support during a 60° banked turn while maintaining altitude?

• 23 pounds.

• 28 pounds.

• 40 pounds.
