Pete, 
While ShortAircraftNameOk is a great feature, I have a suggestion to make it even better.  :wink:  
What I really care about is the aircraft TYPE (i.e. 737, 747, etc) when I'm matching aircraft to a particular configuration. Unfortunately, the aircraft title (as listed in aircraft.cfg, and which FSUIPC seems to key on) varies wildly by vendor (and even _within_ a vendor! - for example, PMDG). 
My suggestion is: create a new .ini setting to allow ShortAircraftNameOk to perform a _substring_ search within the title. 
Now, fortunately, I do have a viable workaround: I have edited all of my aircraft.cfg files such that have a consistent title prefix. 
Let me know what you think... 
Thanks! 
- Bill
