aerial vehicles (UAVs), often referred to as are aircraft that operate without a human pilot board. They can be controlled remotely or and are used for a wide variety of including surveillance, delivery, and even operations. Landing and Take-Off: Unmanned aerial (UAVs), often referred to as drones, are aircraft operate without a human pilot on board. They can controlled remotely or autonomously, and are used a wide variety of purposes including surveillance, and even military operations. A type of drone as fixed-wing drone is an aerial vehicle that rigid wings, a fuselage, tails, a propeller, and a to cover long distances at high speeds. Unlike drones, they cannot hover or land at specific requiring a runway or a net for landing. Thus all (for example fixed-wing drones) cannot do landing. A fixed-wing drone is an aerial vehicle utilizes rigid wings, a fuselage, tails, a propeller, a motor to cover long distances at high speeds. other drones, they cannot hover or land at points, requiring a runway or a net for landing. all drones (like fixed wing drones) cannot do landing. Hence statement I is not correct. Hovering: Again, unlike other drones, fixed wing drones cannot hover or land at points, requiring a runway or a net for landing. statement I is not correct. Usage: UAVs come in many configurations, Multirotors (e.g., quadcopters) Fixed-wing Hybrid VTOLs High-endurance military UAVs (e.g., drones) Many of these cannot rely solely on due to power and endurance limitations. density of batteries is lower than fuel: For long- UAVs, especially fixed-wing or military UAVs, cannot provide sufficient power or duration. statement-III is not correct.
