Enables autopilot for Spirit of St. Louis.  Slim would've loved this!  If you also use the PMS50 GTN750 mod, or other autopilot control panel you can see autopilot modes and even navigate with the GPS.  Yes it is cheating.

 

Autopilot can be controlled with hardware control bindings or other mods or keyboard.   The autopilot panel pictured is from the paid version of the PMS50 GTN750 add on. You don't need it, autopilot can be controlled with keyboard commands or control bindings.
