My question is about the "flight dynamic model" of FMS and/or other similar
simulators.
Do you know any Delphi and/or C/C++ flight dynamics model code which takes
the rudder, elevator, throttle, aileron, airplane's position, velocity and
attitude (roll, pitch, yaw angles) as inputs and calculates the airplane's
next position, velocity and attitude?
