Question 1

What is the primary consequence of operating a small UAS with the Center of Gravity (CG) too far aft?

Accepted Answer

The aircraft will become less stable at all speeds and recovery from a stall may be impossible.

Answer

The aircraft will experience increased airspeed and stability.

Answer

The aircraft will tend to pitch nose down automatically.

Question 2

How does high density altitude affect the performance of a small UAS?

Accepted Answer

It decreases performance due to reduced propeller efficiency and reduced aerodynamic lift.

Answer

It improves performance because the air is less dense.

Answer

It increases the efficiency of the battery.

Question 3

When computing weight and balance, the 'datum' is:

Accepted Answer

An imaginary vertical plane or line from which all measurements of arm are taken.

Answer

The exact center of the propeller hub.

Answer

The total weight of the aircraft empty.

Question 4

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 5

Where should a remote pilot look to find the official weight and balance limits for their specific small UAS?

Accepted Answer

The manufacturer's operating manual or Pilot's Operating Handbook (POH).

Answer

14 CFR Part 107 regulations.

Answer

The FAA DroneZone website.

Question 6

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 7

Which of the following is true regarding lithium polymer (LiPo) batteries used in most small UAS?

Accepted Answer

They are highly flammable and can catch fire if punctured, overcharged, or exposed to extreme heat.

Answer

They perform best when stored fully depleted.

Answer

They are immune to temperature extremes.

Question 8

Overloading a small UAS will likely result in which of the following?

Accepted Answer

Decreased climb rate, decreased maneuverability, and shorter battery life.

Answer

Increased flight time due to greater momentum.

Answer

Increased maneuverability.

Question 9

As altitude increases, what happens to the true airspeed of a fixed-wing sUAS flying at a constant indicated airspeed?

Accepted Answer

True airspeed increases because the air is less dense.

Answer

True airspeed decreases.

Answer

True airspeed remains the same.

Question 10

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.
