Loading and performance - FAA Part 107 Drone Quiz

Question 1

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 2

You are flying a quadcopter and maneuvering aggressively, causing steep banks and rapid pull-ups. How does this affect the structural integrity of the drone?

Accepted Answer

It increases the load factor, placing higher stress on the airframe and motors.

Answer

It strengthens the frame by testing its flexibility.

Answer

It reduces the load factor because the drone is moving quickly.

Question 3

When an aircraft's center of gravity is located forward of the forward CG limit, the aircraft:

Accepted Answer

Will be highly stable, but will require more elevator pressure to raise the nose, decreasing performance.

Answer

Is highly unstable and difficult to control.

Answer

Will stall at a lower airspeed.

Question 4

If an unmanned aircraft weighs 30 pounds, what approximate weight would the structure be required to support during a 60-degree banked turn while maintaining altitude?

Accepted Answer

60 pounds.

Answer

30 pounds.

Answer

45 pounds.

Question 5

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 6

Why should a remote pilot avoid storing LiPo batteries fully charged for extended periods (e.g., several weeks)?

Accepted Answer

It degrades the battery's chemical structure, leading to swelling (puffing) and reduced lifespan.

Answer

The battery will become too cold.

Answer

The battery will permanently lock and cannot be used again.

Question 7

What is a recommended practice when flying a small UAS in very cold temperatures?

Accepted Answer

Keep the batteries in a warm environment (like a heated car or inside your jacket) until immediately before the flight.

Answer

Pre-chill the batteries outside to acclimate them to the weather.

Answer

Discharge the battery to 50% before flying to prevent freezing.

Question 8

The angle of attack is defined as the angle between the chord line of an airfoil and the:

Accepted Answer

Direction of the relative wind.

Answer

Pitch angle of the aircraft.

Answer

Rotor plane of rotation.

Question 9

During a preflight inspection, you notice your LiPo battery is slightly swollen or puffy. What should you do?

Accepted Answer

Do not fly with it, safely discharge it, and dispose of it properly, as it poses a severe fire risk.

Answer

Use it for short flights only.

Answer

Compress it gently to flatten it out before flying.

Question 10

Which weather conditions should a remote pilot consider primarily because they severely degrade lithium battery performance?

Accepted Answer

Sub-freezing temperatures.

Answer

High humidity.

Answer

High temperatures.
