Exam quiz Flight performance and planning - EASA Drone License A2

Question 1

Why is it important to physically check that the propellers are securely tightened before taking off?

Accepted Answer

A loose propeller can detach mid-flight, causing a sudden and total loss of aerodynamic control resulting in a catastrophic crash

Answer

Loose propellers will cause the battery to overcharge

Answer

Loose propellers will scramble the GPS signal

Answer

It helps the drone fly faster

Question 2

For a multirotor to initiate a climb from a stable hover, the total thrust generated by the rotors must be:

Accepted Answer

Greater than the total weight of the drone

Answer

Exactly equal to the total weight of the drone

Answer

Less than the aerodynamic drag

Answer

Directed horizontally

Question 3

Why is it dangerous to fly a drone behind a large, solid structure like a metal building?

Accepted Answer

It blocks both the radio control link (VLOS and telemetry) and the GPS satellite signals, highly increasing the risk of signal loss and a crash

Answer

The building will absorb the drone's battery charge

Answer

The drone will automatically initiate a landing procedure as soon as it sees a wall

Answer

It is not dangerous if the drone has obstacle avoidance sensors

Answer

14 years old

Answer

18 years old

Question 5

When planning a flight in an unfamiliar urban environment, what is a significant technical risk regarding GPS/GNSS?

Accepted Answer

The 'Multipath Effect', where satellite signals bounce off tall buildings, causing inaccurate positioning or a sudden loss of GPS lock

Answer

The drone's battery will drain twice as fast

Answer

The Wi-Fi networks will permanently disable the compass

Answer

The propellers will generate more noise

Question 6

What is the function of the Flight Controller in a drone?

Accepted Answer

Answer

There is no difference in their reaction

Question 13

What is the primary aerodynamic function of the wing on a fixed-wing UAV?

Answer

To act as a physical bumper against obstacles

Question 14

If the drone enters ATTI mode (GPS loss) while flying near obstacles, what is the correct manoeuvre to avoid collisions?

Accepted Answer

Manually control the horizontal position by compensating for wind drift with the sticks while maintaining a safe altitude

Answer

Turn off the motors immediately to avoid major damage

Answer

Activate the Return to Home (RTH) button

Answer

Increase maximum speed to reacquire the signal

Question 15

Adding an asymmetrical payload to one side of the UAS will:
