Question

With reference to Unmanned Aerial Vehicles (UAVs), consider the following statements:All types of UAVs can do vertical landing.All types of UAVs can do automated hovering.All types of UAVs can use battery only as a source of power supply.Which of the statements given above is/are correct?

Accepted Answer

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