I'd like to calculate some V speeds (in Nasal) as part of one of the
Airbus aircraft I'm working on. 
  I'm wondering if anyone knows if there is stuff already done in JSBsim
that appears under /fdm/jsbsim/....
  properties that might be useful to help calculate any of the
following;

Vs - stall
Vs0 - stall landing
Vr - rotate
Vref - landing reference speed
Vfe  - flap extended
Vc - optimal cruise

Now some of these are dependant on working out other things, eg: rotate
is dependant on stall speed. 
and I don't expect JSBsim to calculate the things I need, but it seems
JSBsim has already done a lot of
the work that goes into calculating these things out, such as air
density, wing area, gross weight etc.

I'm also looking for a single source that has all the formulae in one
place, I've found things in different
places, but if anyone has seen a good single source, I'd appreciate any
pointers. I find reading mathematical
formulae does my head in trying to convert it to code, I still have
problems working out my change on the
bus, so all these Greek symbols a lot of articles like to use don't
help. 


Cheers
  Scott.
