Definition
A flight control system that automatically maintains an aircraft in level flight or on a set course, and can be programmed to execute changes in heading, altitude, and airspeed without continuous manual input from the pilot.
Plain English
A system that flies the aircraft for you, holding it steady or following a set path, so you don't have to keep your hands on the controls every second.
Context Anchor
Pilots encounter this term when learning aircraft systems, cockpit controls, and how some aircraft can maintain a selected direction or altitude during flight.
Derivation
From Greek 'autos' meaning 'self' and 'pilot' from Italian 'pilota' (one who steers a ship). Literally 'self-steerer' — a device that steers the aircraft on its own.
Why Pilots Care
Reduces pilot workload on long flights, improves precision during cruise, and allows attention to navigation, communication, and systems monitoring.
Analogy
Like cruise control in a car that holds speed without the driver pressing the pedal the whole time, except the automatic pilot also keeps the wings level and the nose on a chosen heading.
Intuition Check
Automatic pilot does not mean the aircraft no longer needs a pilot. It means a system is moving the controls according to settings the pilot selects and monitors.
Example Sentence 1
Once established in cruise at 8,500 feet, the pilot engaged the automatic pilot to hold altitude and heading.
Example Sentence 2
During a long cross-country flight the automatic pilot kept the wings level while the pilot checked weather updates on the radio.
