With reference to Unmanned Aerial Vehicles (UAVs), consider the following statements: I. All types of UAVs can do vertical landing. II. All types of UAVs can do automated hovering. III. All types of UAVs can use battery only as a source of power supply. How many of the statements given above are correct?
Explanation
None of the statements given above are correct because UAVs vary widely in design and capabilities.
I. Not all UAVs can perform vertical landing; for example, fixed-wing UAVs typically require runways and cannot land vertically. II. Similarly, while certain UAVs like rotorcraft can hover, others cannot due to their fixed-wing design. III. Additionally, UAVs can be powered by various sources, including fuel engines and solar power, not just batteries. Understanding these distinctions is crucial for assessing UAV functionality and adaptability, which is relevant for topics related to technology and defense in the UPSC syllabus.
