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?
Unmanned Aerial Vehicles (UAVs) are aircraft systems operated without a human pilot onboard. Their capabilities depend on design type (like fixed-wing, multirotor, or hybrid) and power source. ❌ I. Vertical landing – Only VTOL and multirotor drones can do vertical landings. Fixed-wing UAVs cannot. ❌II. Automated hovering – Only multirotor drones and advanced hybrids can hover. Fixed-wing UAVs cannot hover at all. ❌ III. Battery-only power – Not all UAVs use batteries. Larger ones may use fuel, hybrid, or solar power. None of the statements are correct.
