UAG - Unmanned Aircraft General UAS Loading and Performance Questions and Answers

Question 1

A remote pilot is preparing for a flight on a hot, humid day at an airport with a high field elevation. Which of the following effects on UAS performance should be anticipated?

Accepted Answer

Reduced aircraft performance due to high density altitude.

Answer

Increased propeller efficiency and longer flight times.

Answer

Decreased takeoff distance and improved climb performance.

Answer

No significant impact on performance, as UAS are unaffected by density altitude.

Question 2

If the center of gravity (CG) of a fixed-wing unmanned aircraft is moved to the most aft limit, which performance characteristic is most likely to be experienced?

Accepted Answer

Less stability and a lower stall speed.

Answer

Increased longitudinal stability and higher stall speed.

Answer

Improved stall recovery characteristics.

Answer

A requirement for less tail-down force to maintain level flight, leading to increased drag.

Question 3

What is the primary reason a remote pilot in command must calculate the weight and balance of their UAS before every flight?

Accepted Answer

To comply with the manufacturer's specified limits for safe operation.

Answer

To ensure the UAS does not exceed the 100 mph speed limit.

Answer

To verify the battery is fully charged.

Answer

To determine the maximum flight altitude for the mission.

Question 4

During a coordinated 60-degree banked turn, the load factor on a UAS would be approximately:

Accepted Answer

2 Gs

Answer

1 G

Answer

1.5 Gs

Answer

3 Gs

Question 5

A remote pilot plans to attach a new, heavier camera payload to their multirotor UAS. Which of the following is the most significant performance change the pilot should expect?

Accepted Answer

Decreased flight endurance and potentially sluggish control response.

Answer

Increased maneuverability and faster response to control inputs.

Answer

Longer flight endurance due to increased momentum.

Answer

A lower center of gravity, which always improves stability.

Question 6

When reviewing a takeoff performance chart in the UAS Flight Manual, what is the effect of a headwind?

Accepted Answer

It decreases the takeoff distance required.

Answer

It increases the takeoff distance required.

Answer

It has no effect on takeoff distance.

Answer

It requires a higher rotation speed.
