The autopilot setting dialog of FlightGear.

An autopilot (AP) is a mechanical, electrical, or hydraulic system used to guide a vehicle without assistance from a human being. Most people understand an autopilot to refer specifically to aircraft, but self-steering gear for ships, boats, space craft and missiles is sometimes also called by this term.

The autopilot of an aircraft is sometimes referred to as "George".

Autopilot Settings

The AP Settings dialog could be found at Autopilot > Autopiilot Settings.

Heading control

  • Wings Level: enable this to keep your plane horizontal.
  • Heading Bug: located on the compass rose of your instrument panel is a movable heading bug, the purple triangles that are pointing at your runways heading (283 for KSFO default). This bug is moved around the rose by setting the Heading Bug. The heading bug can be used several ways. When hand flying the aircraft turn the bug to your desired heading. This way you will have a constant visual reminder. If Air Traffic Control gives you a new heading move the heading bug to the new heading and you have your visual reminder.
  • True Heading: your true heading as shown on the compass (of the HUD) and MP Map.
  • NAV1 CDI Course: use only with ILS.

Velocity control

  • Speed with Throttle: speed will be regulated to the selected speed by controlling throttle.
  • Speed with Pitch: your plane will be pushed down or up to reach the selected speed. This can not be used during takeoff, landing or low altitude flights. Doing so could cause a crash.

Pitch/Altitude control

  • Vertical Speed:
  • Pitch Hold: pitch degrees of your plane. Use a negative number to lower your nose.
  • AoA Hold: ?
  • Altitude Hold: the desired altitude of your plane in feet (FL1=100 ft, FL25=2500 ft etc.).
  • AGL Hold: ?
  • NAV1 Glideslope: use only with ILS.
