Loading and performance - FAA Part 107 Drone Exam Prep

Question 1

What are the four forces that act on an aircraft in flight?

Accepted Answer

Lift, weight, thrust, and drag.

Answer

Lift, gravity, power, and friction.

Answer

Lift, weight, speed, and drag.

Question 2

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 3

What is the effect on the propeller efficiency of low density altitude?

Accepted Answer

Propeller efficiency is increased.

Answer

There is no effect on propeller efficiency.

Answer

Propeller efficiency is decreased.

Question 4

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.

Question 5

You are flying a fixed-wing drone. If you double the airspeed, what happens to the parasite drag?

Accepted Answer

It quadruples.

Answer

It doubles.

Answer

It remains the same.

Question 6

When does an aerodynamic stall occur?

Accepted Answer

When the critical angle of attack is exceeded.

Answer

When the airspeed drops below 10 knots.

Answer

When the engine loses power.

Question 7

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 8

Before every flight, who is responsible for determining that the sUAS is properly loaded and within its weight and balance limits?

Accepted Answer

The Remote Pilot in Command (PIC).

Answer

The manufacturer.

Answer

The owner of the aircraft.

Question 9

If you add a payload to your drone that shifts the CG beyond the aft limit, what is the most likely aerodynamic consequence?

Accepted Answer

The drone will be tail-heavy and highly unstable, making it difficult or impossible to control.

Answer

The drone will be nose-heavy, causing it to descend rapidly.

Answer

The drone will automatically engage a return-to-home protocol.

Question 10

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

Accepted Answer

Pilot's Operating Handbook or UAS Flight Manual.

Answer

Aeronautical Information Manual (AIM).

Answer

Aircraft Weight and Balance Handbook.
