Question 1

The distance an aircraft travels over the ground is affected by the wind. If your drone flies at 30 knots indicated airspeed into a 10-knot headwind, what is the approximate ground speed?

Accepted Answer

20 knots.

Answer

30 knots.

Answer

40 knots.

Question 2

What is the relationship between induced drag and airspeed?

Accepted Answer

Induced drag decreases as airspeed increases.

Answer

Induced drag increases as airspeed increases.

Answer

Induced drag is unaffected by airspeed.

Question 3

What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why?

Accepted Answer

Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes.

Answer

Efficiency is increased due to less friction on the propeller blades.

Answer

Efficiency is reduced due to the increased force of the propeller in the thinner air.

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

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 6

Density altitude is defined as:

Accepted Answer

Pressure altitude corrected for non-standard temperature.

Answer

The height above the standard datum plane.

Answer

The actual height of the aircraft above the ground.

Question 7

If an unmanned aircraft weighs 45 pounds, what approximate weight would the aircraft structure be required to support during a 45° banked turn while maintaining altitude?

Accepted Answer

63 pounds.

Answer

72 pounds.

Answer

45 pounds.

Question 8

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 9

Can an aircraft stall at any airspeed?

Accepted Answer

Yes, a stall can occur at any airspeed and any flight attitude if the critical angle of attack is exceeded.

Answer

No, an aircraft can only stall at its published stall speed.

Answer

No, an aircraft cannot stall if the throttle is at 100%.

Question 10

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.
