Pilotless aircraft, also known as unmanned aerial vehicles (UAVs) or drones, are aircraft that operate without a human pilot on board. They are controlled remotely or can fly autonomously using pre-programmed flight plans and onboard sensors. These aircraft are used in various applications, including military operations, surveillance, and aerial photography. The technology behind pilotless aircraft includes advanced navigation systems, GPS, and artificial intelligence. These innovations allow UAVs to perform complex tasks, such as delivering packages or monitoring environmental changes. As the technology continues to evolve, pilotless aircraft are becoming more common in both commercial and recreational settings.
