Exam quiz Flight performance and planning - EASA Drone Quiz A2

Question 1

When a multirotor drone initiates a steep banked turn, the structural load factor:

Accepted Answer

Increases, requiring more thrust to maintain altitude

Answer

Decreases significantly

Answer

Remains exactly the same as in level hover

Answer

Is shifted entirely to the payload

Question 2

According to the '1:1 rule' for ground risk mitigation, how does increasing flight altitude affect the required horizontal safety buffer?

Accepted Answer

The horizontal buffer must increase proportionally with altitude, as a drone falling from a greater height has a wider potential impact radius

Answer

The horizontal distance remains constant regardless of flight altitude

Answer

The buffer can decrease because hitting people is less likely from a high altitude

Answer

The rule only applies during automatic takeoff and landing phases

Question 3

If you discover a small crack on one of the drone's propellers during a pre-flight check, you should:

Accepted Answer

Replace the damaged propeller immediately before attempting to fly

Answer

Repair it with strong adhesive tape and fly cautiously

Answer

Ignore it if the crack is smaller than 1 centimeter

Answer

Only fly at altitudes below 10 meters

Question 4

In Human Factors, what is the primary danger of operating a drone while experiencing mild dehydration?

Accepted Answer

It can cause headaches, fatigue, dizziness, and a significant decrease in cognitive function and concentration

Answer

It causes the pilot to lose their sense of hearing

Answer

It increases the risk of the drone's batteries overheating

Answer

Dehydration only affects physical strength, not piloting skills

Question 5

In the context of Human Factors, 'confirmation bias' during a pre-flight check refers to:

Accepted Answer

The tendency to see what you expect to see, potentially missing obvious faults (e.g., assuming a prop is secure because it usually is)

Answer

Relying on a co-pilot to confirm all checklist items

Answer

Confirming the drone's home point via GPS

Answer

The flight controller's internal validation process

Question 6

What defines 'Controlled Airspace'?

Answer

The physical spinning of the drone when the compass fails

Answer

A software feature that helps the drone land softly

Question 11

How should a pilot fix the 'Toilet Bowl Effect' during a flight?

Accepted Answer

Switch the drone to manual/ATTI mode to stop the erratic GPS-driven circling, land safely, and recalibrate the compass away from magnetic interference

Answer

Switch to automatic RTH mode immediately

Answer

Turn the controller off and on again

Answer

Fly higher to get a better GPS signal

Question 12

In Human Factors, what is the best way to handle 'Peer Pressure' when bystanders urge you to fly closer or perform dangerous maneuvers?

Accepted Answer

Assert your authority as the Remote Pilot in Command, decline the requests firmly, and strictly adhere to safety regulations and operational limits

Answer

Comply with their requests briefly to keep them happy

Answer

Give the controller to the bystanders so they take liability

Answer

Fly faster so the maneuvers are completed quickly

Question 13

What is 'Yaw' in flight dynamics?

Answer

The lateral movement of the drone sliding left or right

Answer

The angle of the camera gimbal relative to the horizon

Answer

A sudden drop in altitude

Question 14

Under EASA Open category rules, is it permissible to operate a drone autonomously without the possibility of pilot intervention?

Accepted Answer

No, the remote pilot must maintain control or the ability to intervene and take command at all times

Answer

Yes, but only for mapping missions

Answer

Yes, as long as the drone has a C3 class mark

Answer

Only if flying completely beyond visual line of sight (BVLOS)

Question 15

What is the proper way to dispose of a severely swollen or damaged LiPo battery?

Question 16

If you are operating near an airport, what is the primary risk you must mitigate?

Accepted Answer

Collisions with low-flying manned aircraft taking off or landing, which can result in catastrophic accidents

Answer

The noise of your drone disturbing passengers in the terminal

Answer

Answer

The airport radar charging the drone's battery too quickly

Question 17

High video latency during an FPV or screen-guided flight can lead to:
