b) FDM - ada.cxx, ada.hxx have been updated with the faux, daux and iaux arrays that you created in flight.hxx. In Flight.hxx I use the get_V_north_rel_ground() set of functions. Please do not comment them out. If you dont comment them, you dont have to forcibly return zero vale to get_Vx(),get_Vy() & get_Vz() in cockpit.cxx.
