Question 1
1 / 15

What is the primary purpose of ensuring proper radio frequency management during drone operations?

Explanation: Proper radio frequency management ensures that drone operations do not interfere with other critical communication systems, maintaining safety and compliance.

Reference: Reg CELEX_02018R1139-20241201_EN_TXT Art 0

Question 2
2 / 15

Which frequency band is commonly used for drone operations in Europe?

Explanation: The 2.4 GHz and 5.8 GHz frequency bands are widely used for drones because they balance range and data transfer efficiency.

Reference: Reg CELEX_32019R0947_EN_TXT Art 0

Question 3
3 / 15

What is the consequence of operating a drone on an unauthorized frequency band?

Explanation: Using unauthorized frequency bands can interfere with other systems and result in penalties as outlined by regulatory authorities.

Reference: Reg CELEX_32019R0945_EN_TXT Art 0

Question 4
4 / 15

What is the function of a frequency-hopping spread spectrum in drone communication systems?

Explanation: Frequency-hopping spread spectrum minimizes signal interference by rapidly switching between different frequencies.

Reference: Reg CELEX_02018R1139-20241201_EN_TXT Art 0

Question 5
5 / 15

Which authority oversees radio frequency regulations for drones in Europe?

Explanation: EASA is the primary regulatory authority for aviation, including drone operations, in European airspace.

Reference: Reg CELEX_02018R1139-20241201_EN_TXT Art 0

Question 6
6 / 15

Why is it important to check for local frequency regulations before flying a drone?

Explanation: Local frequency regulations ensure drones do not interfere with critical services, such as emergency communications.

Reference: Reg CELEX_32019R0947_EN_TXT Art 0

Question 7
7 / 15

What does 'line-of-sight' communication mean in the context of radio frequencies?

Explanation: Line-of-sight communication refers to unobstructed radio signal transmission between the drone and the controller.

Reference: Reg CELEX_32020R0639_EN_TXT Art 0

Question 8
8 / 15

What is the maximum range typically achievable using 2.4 GHz radio frequency under ideal conditions?

Explanation: Under ideal conditions, the 2.4 GHz frequency can achieve a range of up to 10 km, depending on the environment and equipment used.

Reference: Reg CELEX_32020R0746_EN_TXT Art 0

Question 9
9 / 15

What role does signal encryption play in drone communication?

Explanation: Signal encryption ensures secure communication between the drone and its controller, preventing unauthorized access or interference.

Reference: Reg CELEX_32019R0945_EN_TXT Art 0

Question 10
10 / 15

What is a 'channel' in radio communication for drones?

Explanation: A channel refers to a specific frequency allocation within a band, allowing multiple devices to communicate without interference.

Reference: Reg CELEX_32019R0947_EN_TXT Art 0

Question 11
11 / 15

What action should be taken if signal interference is detected during drone operation?

Explanation: Landing the drone immediately prevents potential loss of control due to signal interference, ensuring safety.

Reference: Reg CELEX_32020R1058_EN_TXT Art 0

Question 12
12 / 15

What is the significance of the 5.8 GHz band in drone operations?

Explanation: The 5.8 GHz band provides higher data transfer rates, making it suitable for video transmission and control in congested areas.

Reference: Reg CELEX_32021R1166_EN_TXT Art 0

Question 13
13 / 15

What is the role of the ITU in drone frequency regulations?

Explanation: The International Telecommunication Union (ITU) allocates global radio frequencies to ensure harmonized usage across countries.

Reference: Reg CELEX_32022R0425_EN_TXT Art 0

Question 14
14 / 15

What is the impact of physical obstructions on radio signal strength?

Explanation: Physical obstructions such as buildings or trees can block or weaken radio signals, reducing communication effectiveness.

Reference: Reg D0593E_2024-07-10_06.26.37_EAR-for-Unmanned-Aircraft-Systems Art 0

Question 15
15 / 15

Why is it important to maintain a clear frequency spectrum during drone operations?

Explanation: A clear frequency spectrum ensures reliable communication between the drone and its controller, reducing risks of signal interference.
