UPSC Previous Year Question | Prelims GS | 2025

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 the source of power supply. How many of the statements given above are correct?

  1. Only one
  2. Only two
  3. All the three
  4. None

Answer

Correct Answer

None

Explanation

Not all UAVs can perform vertical landing (fixed-wing UAVs require runway-style landings), not all can hover (fixed-wing types cannot), and not all UAVs use only batteries (many use fuel-powered engines, especially larger/longer-range drones). Hence none of the three statements is correct.
