So, basically, I first figure out its orientation and interpolate
between static and dynamic pressure, then I use the difference between
the pressure from the pitot and static systems to calculate airspeed.
Does anyone have a formula or table for the second part (I guess I
could dig through the JSBSim source)?


All the best,
