Question 6
6 / 10

In the A2 subcategory, which type of sensor is required to maintain safe flight operations during low visibility conditions?

Explanation: An Inertial Navigation System (INS) is crucial during low visibility as it operates independently of external signals like GPS or visual cues.

Question 9
9 / 10

Which sensor combination is most effective for maintaining stability in windy conditions?

Explanation: The inertial navigation system and barometric altimeter work together to ensure stability by tracking movement and measuring altitude changes.

Reference: Reg CELEX_02018R1139-20241201_EN_TXT Art 0

Question 10
10 / 10

What is the purpose of an optical flow sensor in drone navigation?

Explanation: Optical flow sensors detect motion relative to the ground, helping the drone maintain its position and stability during hover operations.
