Rook Zimbabwe is right.
simulation wise its better to use a physics engine.
the planes engine turns the propellar which produces thrust that accelerates the plain.
ex: thrust = enginespeed * propellarcoeff
the planes wings produces lift based on airspeed
ex: lift = airspeed^2 * coord * span * liftcoeff * rho * 0.5
coord and span is the width and height of wing and rho is air density.
horizontal and vertical stabilizers which are the wings at the rear of the plane will produce roll, pitch and yaw forces based on their angle of attack.
ex: wforce = airspeed^2 * coord * span * sin(wing angle) * rho * 0.5
these are just some basics that can get you started.
