Loading and performance - FAA Part 107 Drone Exam Prep

Question 1

How do you calculate the Center of Gravity (CG) of an aircraft?

Accepted Answer

Divide total moment by total weight.

Answer

Divide total weight by total arm.

Answer

Multiply total weight by total moment.

Question 2

Which aircraft characteristic is most negatively affected by an increase in density altitude?

Accepted Answer

Climb performance and overall lift generation.

Answer

Maximum speed.

Answer

Radio range.

Question 3

If the temperature increases from 60°F to 90°F at your flying site, what happens to the density altitude and your drone's performance?

Accepted Answer

Density altitude increases, and drone performance decreases.

Answer

Density altitude decreases, and drone performance increases.

Answer

Density altitude increases, and drone performance increases.

Question 4

What increases the load factor on a fixed wing airplane?

Accepted Answer

Level turn.

Answer

Power off stall.

Answer

Steady state climb.

Question 5

What is 'load factor' in aviation?

Accepted Answer

The ratio of the total load supported by the aircraft's wings/rotors to the actual weight of the aircraft and its contents.

Answer

The total weight of the aircraft including its payload.

Answer

The amount of drag generated by the payload.

Question 6

During a 60-degree banked level turn, what is the approximate load factor (G-force) exerted on the aircraft?

Accepted Answer

2.0 Gs.

Answer

1.5 Gs.

Answer

1.0 G.

Question 7

Frost on the wings or propellers of a small UAS will:

Accepted Answer

Disrupt the smooth flow of air, reducing lift and increasing drag, potentially preventing takeoff.

Answer

Have no significant aerodynamic effect, though it adds slight weight.

Answer

Increase lift by changing the camber of the airfoil.

Question 8

In weight and balance calculations, 'moment' is defined as:

Accepted Answer

Weight multiplied by the arm.

Answer

Weight divided by the arm.

Answer

The total duration of the flight.

Question 9

If the Center of Gravity (CG) is too far forward, how does it affect the flight characteristics of an aircraft?

Accepted Answer

It makes the aircraft nose-heavy, requiring more back-pressure or elevator trim to maintain level flight.

Answer

It increases the maximum flight time.

Answer

It decreases the stalling speed.

Question 10

How does an increased load factor affect the performance of a small UAS?

Accepted Answer

It increases the stall speed and requires more power to maintain altitude.

Answer

It decreases the stall speed and increases flight time.

Answer

It has no effect on performance.
