Aerodynamic simulation is a really tough problem to take on. I'd venture to guess that it's in part due to not having a complete set of theories/equations around fluid dynamics. From what I hear, X-Plane comes really close to this. But yes, skill-transfer aside, I'd guess any airborne vehicle trained in a simulator that lacks environmental effects, ground effects, induced drag effects...etc in its physics calculation is not going to perform well in the real-world.
