Definition
Flight conducted by an aircraft that controls itself, making decisions and executing maneuvers without direct moment-to-moment input from a human pilot. The aircraft uses onboard computers, sensors, and pre-programmed logic to navigate, respond to conditions, and complete the flight.
Plain English
An aircraft that flies itself. No one is steering or making the decisions in real time -- the aircraft's own systems are doing it.
Context Anchor
Seen in discussions of unmanned aircraft, advanced flight control systems, and aircraft that can follow a route or perform tasks with limited human input.
Derivation
From the Greek 'autos' (self) and 'nomos' (law or rule), meaning 'self-governing.' An autonomous aircraft governs itself in flight rather than being governed by a pilot.
Why Pilots Care
Pilots need to understand autonomous flight to safely share airspace with unmanned aircraft and to prepare for oversight roles in increasingly automated cockpits.
Analogy
Similar to a self-driving car that navigates and responds to traffic without the driver touching the wheel.
Intuition Check
Autonomous flight does not mean the aircraft is free to do anything it wants. It means the aircraft can carry out flight actions by itself within programmed limits and assigned instructions.
Example Sentence 1
The delivery drone completed its route in fully autonomous flight, adjusting its path around a thunderstorm without any input from the operator.
Example Sentence 2
Operators must verify all systems before allowing autonomous flight in controlled airspace.
