Abacus Vickers Super VC10

[lerrysan]

I just purchased the Vickers Super VC10 from Abacus, and when I took off I noticed that I had the white trails on the wings. I know that the trails are a new fiture in FSX, but I use FS9. I was wondering if there is someone out there that knows if this can be implemented in every aircraft in my hangar. I know how to work with the aircraft.cfg file and such, I just dont know where the codes would be placed.... and what codes to be exact... Can anyone tell me what I should be looking for?
