Right now there is an independent environment node which calculates the atmosphere model, its structure is copied onto the ModelPlane class and there is also an AirData member which has the aerodynamic angles.
Obviously there is data duplication here which should be dealt with.
The Airdata class holds the relative airspeeds and the aerodynamic angles, data which is not described in the SimEnvironment message.
Considering of closing this one.
