Hi all,
just for your information. I'm still working on a 2D-panel for the 707:

In the next weeks, I will release a first version.
Kind regards

Hello all,
is it possible to derive the transfer function from jsbsim fdm
coefficients. I know the way to calculate the parameters like Clalpha
for a operation point. But for a root locus analyse I need the transfer
function (Root locus is used to calculate the PID-Controller parameter)

the test controller and a little nasal script for logging.

Hello Hans-Georg
I guess the 707 and flightmodel comes under the GPL so I guess
you can modify it as you wish maintaining the terms of the GPL.

It would be great, if you also test the code.

Hi all,
I adapted the 2D-panel of a 707 from George Carty for FlightGear and
merged it with the 3D-Model of Innis Cunningham.

I found the same bug some days ago and I reported it here on the lists.
Your solution was also my first approach, but it did not work for the
Integrator-part. The value ep_n is wrong for the next cycle.
But after a looot of testing I found this solution:

Hi,
as far as I know, they are not supported by the standard kernel. I am
using the 2.4.27 and I have had the same problem. You have to apply a
patch.

I just compiled the new Atlas-version on my Linux-Box (Debian 3.1) and
