Did you try scheduling your autoplilot´s height-error to pitch
demand gain with 1/V (speed inverse) ?

ie if u stick in a new value to the FDM then it will react..
That sucks in my oioiion.. I how have to create my own craqo
to make the model. that sucks to me..

I'm working on my motion sim for xmas. Its powered by a vacum cleaner atmo..
One BIG BIG problem - am basicng the cockpit on Bravo and 787
The autopilot heading bug is very violent and JERKS to direction..
How can we solve that problem please because on my motion platform, I
cant keep up with
I haven't looked at these autopilot configurations (at least not for a long
time) but off the top of my head, I think this can all be fixed by tuning
the autopilot.
For instance, lowering the max aileron deflection from (-1 ... 1) down to
maybe (-0.1 ... 0.1) might be an interesting thing to

If you mean this sudden banking when after reaching a new wayoint: yes. It is
known and is still on the bug-list on flightgear.org anywhere.

Control surface deflection rate can be limited by inserting a low-pass
filter
between the output of the final PID-controller and the control surface.
THis
is done in the autopilot config file.
