i dcont know if everyone feels the same way but the ai sounds are terrible, every jet sounds the same...there arent any real life sounds for ai planes or instructions on how to work with that.. does anyone know what to do about that aweful annoying sound when the aircraft passes by that is trhe same for any aircraft

Try this out for size, it's payware, but makes a significant difference in AI sounds, with appropriate engine sounds for all kinds of jets and props. http://www.flight1.com/products.asp?product=audioenv

Only one I know about is FSHotSFX, which is no longer supported but can still be purchased. It does NOT work on Vista or System 7 - only XP and earlier. If you think about buying it, try the demo first, and make SURE it works OK for you.Hope this helps,
