Autopilot

System to maintain vehicle trajectory in lieu of direct operator command

An autopilot is a system used to control the path of an aircraft without requiring constant intervention by a human operator. The autopilot does not replace human operators, but it assists them allowing them to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines.
