I have downloaded a matlab-simulink program that
uses flightgear interface. For a flight dynamics model it requires external fdm
so I command from that program and visualise in flight gear. My question

Hi,
A few days ago I couldn't even spell CVS, and then I implemented it for
our company. It definitely is not worth it if the user's aren't clued up.
I added Perl scripts, web interfaces, you name it. But unfortunately,
the user factor always come into play...
Just my thoughts ...

I understand that some new autopilots for small planes are

creating excessive stresses.

Hi,

I have a 310 OM from around 1970 (not that I'm likely to fly a twin

I couldn't agree more, I flew the c-310 back in the 80's on a night mail
run, and found it very stable to fly. It had sort of a big airplane
feel and pretty much stayed were you put it. The other thing that I

I like the model, after I get back from holiday I'll get out my spitfire

I wondered if you could send me the script, or tell me how I might do
this. I know Perl. I know almost nothing about GPS except that it's
probably the coolest toy I've ever played with.
Not so much of a technical issue, but I found Andy to be very responsive
and even got me started on my "pirate" and answered probably quite basic
questions. Something to consider too imho :).

Bringing this up again is a little scary, but was JSBsim changed to report
position at a fixed point on the airframe? IIRC we talked about reporting
the nose position. The view code has been modified to handle this, so I'm
