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?
- AOnly one
- BOnly two
- CAll the three
- DNoneCorrect
Explanation
None of the statements about UAVs are universally correct:
I. All types of UAVs can do vertical landing: False. Fixed-wing UAVs typically require runways for takeoff and landing, unlike rotary-wing drones that can perform vertical takeoff and landing (VTOL).
II. All types of UAVs can do automated hovering: False. Fixed-wing UAVs cannot hover as they need forward motion to generate lift. Only multirotor and helicopter-type UAVs can hover in place.
III. All types of UAVs can use battery only as a source of power: False. While many small UAVs use batteries, larger military and commercial UAVs often use fuel engines, solar panels, or hybrid power systems for extended flight times.
