AFAIKT the waypoint mode is tied to the true heading hold mode. What you can do is to modify the u_min and u_max around line 137 in generic-autopilot.xml to allow the autopilot to command a greater bank angle say 40 degrees instead of the current 20 degrees.

The system is excellent for detail modeling, but not so great for those who are not controller artists. Isn't there some way we can make this easier without losing the benefit of flexibility? BTW maybe a lookahead like the 747 is using for nav-hold would help auto-tune the heading bug.

Hi Jim, I was the one who asked this question but when i tried to implement the solution it resulted in the same flight behaviour. I will detail the changes i implemented so you can see if i did anything incorrectly. 1) I changed, in file Aircraft/c172/c172-610x-null-set.xml, pathAircraft/c172/610x-autopilot.xml/path to pathAircraft/Generic/generic-autopilot.xml/path 2) I call the program passing in aircraft=c172. When a waypoint is added the plane still flys in circles and does not fly towards the waypoint, Seamus On Thu, 20 May 2004, Jim Wilson wrote: Just change the autopilot back to the generic version in the *-set.xml file.
