I have quite a large number of add-on aircraft... about 4 times as many as the default aircraft in FSX. Some of these add-ons I have had to tweak, so they work properly in FSX. I for one will be annoyed if I can't use these aircraft in MS Flight. In fact that could be a deal-breaker.
Has anyone given feedback to MS, saying that an important part of the 'wishlist' is full compatibility with FSX (and preferably FS2004) aircraft?
