I have Flight Simulator 5.0 (disk) and I recently downloaded some non flight
shop aircraft. I'm having trouble selecting the aircraft from the 'Aircraft'
menu...the game locks up when I try to select the aircraft. I read a
readme.txt file and it said that the game may lock up because there are no
aircraft specifications. Does anyone know how I can change this or how I can
select an aircraft without going into the 'aircraft' menu?

Thanks.
Justin,
Check the documentation that comes with the non-FSFS aircraft, but
I believe they all require at least FS5.0a. The "a" upgrade is free. It
used to be at Microsoft's website and you might try here. Other than that,
about the only speciality about non-FSFS planes I recall is you must
have "See Aircraft Shadow" turned off in Preferences.
