Question 1
1 / 15

What is the primary concern when storing lithium-ion batteries for your drone?

Explanation: Lithium-ion batteries should be stored in a cool, dry place to prevent degradation and reduce the risk of fire. Exposure to heat or moisture can be hazardous.

Reference: No specific EASA regulation provided in the sources.

Question 2
2 / 15

How often should you inspect your drone’s propulsion system for wear and tear?

Explanation: Inspecting the propulsion system before every flight ensures safe operation and helps identify potential failures early.

Reference: No specific EASA regulation provided in the sources.

Question 3
3 / 15

What is the recommended action if a drone battery shows signs of swelling?

Explanation: Swelling is a sign of battery damage and potential failure. Safe disposal prevents fire risks and ensures compliance with safety standards.

Reference: No specific EASA regulation provided in the sources.

Question 4
4 / 15

Which of the following is true about drone battery charging?

Explanation: Using a manufacturer-recommended charger ensures compatibility and reduces the risk of overcharging or damaging the battery.

Reference: No specific EASA regulation provided in the sources.

Question 5
5 / 15

What is the best way to handle a drone battery after it has been submerged in water?

Explanation: Water exposure can compromise the integrity of the battery, posing a risk of fire or malfunction. Safe disposal is the correct action.

Reference: No specific EASA regulation provided in the sources.

Question 6
6 / 15

What is the role of Electronic Speed Controllers (ESCs) in a drone propulsion system?

Explanation: ESCs regulate the speed and direction of the drone's motors, ensuring stable flight and efficient propulsion.

Reference: No specific EASA regulation provided in the sources.

Question 7
7 / 15

Why should you avoid over-discharging a lithium-ion drone battery?

Explanation: Over-discharging can permanently damage the battery cells, reducing their capacity and increasing the risk of failure.

Reference: No specific EASA regulation provided in the sources.

Question 8
8 / 15

What is the recommended action if a drone motor emits unusual noises during operation?

Explanation: Unusual noises may indicate wear or damage. Inspecting and replacing the motor ensures safe and reliable operation.

Reference: No specific EASA regulation provided in the sources.

Question 9
9 / 15

Which type of drone battery is most commonly used for recreational drones?

Explanation: Lithium-ion batteries are lightweight, have high energy density, and are widely used for recreational drones.

Reference: No specific EASA regulation provided in the sources.

Question 10
10 / 15

What is the main advantage of brushless motors in drone propulsion systems?

Explanation: Brushless motors are more efficient and durable than brushed motors, making them ideal for drones.

Reference: No specific EASA regulation provided in the sources.

Question 11
11 / 15

What should you check first if a drone motor fails to start?

Explanation: A low battery charge can prevent the motor from starting. Checking the charge level is the first troubleshooting step.

Reference: No specific EASA regulation provided in the sources.

Question 12
12 / 15

What is the purpose of a failsafe feature in a propulsion system?

Explanation: Failsafe features are designed to prevent accidents by safely handling system failures, such as motor or battery issues.

Reference: No specific EASA regulation provided in the sources.

Question 13
13 / 15

What should you avoid when charging a drone battery?

Explanation: Leaving a battery unattended during charging can lead to safety risks, including overheating or fire.

Reference: No specific EASA regulation provided in the sources.

Question 14
14 / 15

Which factor most affects drone battery runtime?

Explanation: The weight of the drone directly impacts battery runtime as heavier drones require more energy to stay airborne.

Reference: No specific EASA regulation provided in the sources.

Question 15
15 / 15

What is the first step in troubleshooting a propulsion system malfunction?

Explanation: Inspecting the battery and connections ensures that power is being delivered correctly to the propulsion system.

Reference: No specific EASA regulation provided in the sources.
