Roy Vegard Ovesen:

Here is the KAP140 Two Axis Autopilot update.

I think it's fairly complete now, all the modes are working. I tested the
localizer and glideslope hold and it was pretty stable all the way down to
the middle marker.

In the pilot guide for backcourse hold (REV) mode it says to reset the heading
bug to the _front course_. I haven't figured out how to implement this so for
the time beeing one should reset the heading bug to the _backcourse_. Apart
from this the panel should operate identical to the way the pilot guide
describes.
