Whoops. I meant:
eq(A) dt =
[1, -d psi, d theta; d psi, 1, -d phi; -d theta, d psi, 1] -
[1, 0, 0; 0 1 0;
Thanks for the reply. I've just looked through that section, and it seem that
omega x v
(eq. 1.5-13)
is a recurring theme in dynamics modelling. After doing unit analysis, I
found that it gives acceleration. So I guess I will try making use of it in
my own equations of motion.

Have you taken a look at the Formulation section in the JSBSim Reference
Manual? That might help. See the Documentation link at the top of

Hello all,
As part of a project at school, I have been trying to come up with equations
of motion for an aerial platform, so that I may use the equations to design a
control system. The issue is that I'm having trouble coupling linear and
angular dynamics. Specifically, I need to describe the

In my experience the active runway is designated by the ground radio
station at the field. At small fields it is the same active runway for
take-off and landing. At large busy fields these might be two
different (often parallel) runways. If different non-parallel runways
are designated, they w

Hello everyone ,
I 've been pondering an idea of adding updraft/downdrafts to the

My idea is to calculate wind-speed-from -down , by checking wind speed ,
direction , and the normal of the

Curtis,
Finally getting somewhere on this issue. Using the Seahawk with Apr source
and data, performance is very satisfactory. Generally good frame rates, with
just the odd stagger, which judging by the odd video I have seen on YouTube,
seems to be the general case. Using cvs-head source and da
