An autopilot is a system that automatically controls and navigates a plane or other vehicle.
When pilots are not actively controlling their plane, they put it on autopilot so the aircraft can fly smoothly and safely without needing human intervention. This means that the autopilot will maintain the correct course, altitude, and speed, making long flights easier for pilots to manage. Many modern cars also have an "autopilot" mode, but this is more like a semi-autonomous driving system that assists with steering and acceleration, rather than fully controlling the vehicle. Some companies are even working on developing autopilot systems for self-driving cars, which could one day reduce traffic accidents and make driving easier for people.
A mechanical, electrical, or hydraulic system used to guide a vehicle without assistance from a human being.
Example: I set the autopilot to due south, so I could get some rest.
(of a vehicle) To pilot itself; to drive or travel automatically.
