The starter motor(s) and APU should also be included in the electrical system.
In real life the battery can't keep turning that engine over indefinately.
In the light aircraft it might not be such an issue but when you get to the
commercial jets you have to be very careful about your startup

If you're so stuck on random event generators, go use MSFS. It's full of

I guess this is directed to the model makers.
I am making a model with AC3D and I have five surfaces
that stay white in FG even though I apply a material to them.
I have tried fliping normals or rearranging the vertex order but still
they show white.
The strange thing is that sometimes
Hmmm, Tricky.
David culp sent me the relevant source code.
I'll take a look at it and see what I can do.

Hi, Martin:
I'm pretty busy at the moment doing some rewriting of the JSBSim propulsion
systems, but I will refer you at the moment to a set of notes I wrote for
our gear model. I have not revisited the

It can't be landed on because the deck is not solid (however you can fly
inside and grab lunch). Is there a way to solidify the deck?

I'll send you the code if you like. I've written a bare-bones AI system based

Let me expand on that. If you do come to a stop, and there are no winds at
the moment, then the winds come up after you have stopped, then having
reduced the forces as your velocity goes to zero, you won't

Oh. Why is that?
I tried limiting the ground reactions and found that if you lower them enough
to stop the jitter, the airplane will get blown around by the wind. I
believe this is the relevant bit of
