The problem with a game about building airliners is that they're so much more complex than cars. It's not like you can just weld up a ladder frame and slap an engine on it; like you can with a car.
While aerodynamics are fairly unimportant for cars; it is everything for an airliner. The game must be able to have either fluid dynamics modeling; or very good approximations.
Your best bet right now is to get Kerbal Space Program, a ton of mods for aircraft parts; notably B9 Procedural wings and procedural tanks, and most importantly, the FAR mod with everything set to strict. Obviously it only models the basics like area-ruling, and won't have the more complex issues such as mach-tuck (though lift does shift rearward while passing the transonic range)... but it is as good as you'll find anywhere. If you need an example of the realism it achieves; dutch-roll is a fairly common issue.
