How Autopilot Works

The system receives data from the aircraft’s various mechanisms and responds by inhibiting a particular action in response to another action.

For instance: If the wings are no longer level, the autopilot receives data telling it that, and it activates to correct the problem. Once the wings are level, the loop closes and that communication essentially stops. This repeats with all of the functions of a plane inflight including steering, speed, altitude, and more.

The Pilots are monitoring closely to mind for any issues or inconsistencies.
