Unmanned aerial vehicles

Definition

Unmanned aerial vehicles (UAVs), also known as drones, are aircraft that operate without a human pilot onboard. These versatile machines can be remotely controlled or fly autonomously based on pre-programmed flight plans or more complex dynamic automation systems. UAVs are increasingly utilized in search and rescue operations due to their ability to access hard-to-reach areas, gather real-time data, and provide aerial surveillance in emergency situations.
