Is it possible to delete all aircraft with the exception of one (Including the Default aircraft)?

Yes it is.... why would you want to do that though ?

Becasue I understand that the less add-on's the better. Plus I only want to fly one aircraft, which is the best freeware origenal going, and thats the P-3.

yup, the less aircrafts you have, the faster FS9 will load (but it won't affect fps or anything). i've also deleted every default fs9 aircraft. However, i didn't perminately remove them from the HD (just moved them to a second HD). This is because many freeware/payware planes will alias their panels, sounds, or guages. So it's a good idea to keep them for this reason. -feng

I'm going to check and see if the P-3 Has it's own gauges.

Yea its no problem, I have deleted every default plane :)

It would be a good idea to keep the default Cessna 172 around. If there is a problem loading the aircraft you want, FS9 loads the Cessna- and if it's not there, you get a scary message saying you have to reinstall FS9.Best Regards, Donny :-waveFLYing? It's cool. Trillions of birds and insects can't be wrong.
