Loading & Performance

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

• A. Propeller efficiency is increased.

• B. Propeller efficiency is decreased.

• C. Density altitude does not affect propeller efficiency.

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

• A. Pilot's Operating Handbook or UAS Flight Manual.

• B. Aeronautical Information Manual (AIM).

• C. Aircraft Weight and Balance Handbook.

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.

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

• A. Remote pilot-in-command.

• B. Manufacturer.

• C. Owner or operator.

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

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

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

• C. 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

• A. exceeds the maximum speed.

• B. exceeds maximum allowable operating weight.

• C. 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?

• A. 34 pounds.

• B. 47 pounds.

• C. 38 pounds.

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

• A. Increased performance.

• B. Decreased performance.

• C. No change in performance.

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

• A. can result in loss of control of the aircraft.

• B. increases performance.

• C. 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?

• A. 23 pounds.

• B. 28 pounds.

• C. 40 pounds.
