Wonder if anyone can help-guess here. I´ve identified the wavs that need to be tweaked but Im not sure in which part of the sim they become active:

I know all the wavs starting with "x" are exterior sounds. Im not touching those for now.

These are the ones need to be identified when they start playing:

707idle.wav     = Idle power (that´s easy)
707jet.wav      = ???
707rumble.wav = ???
707thrust.wav  = ???
707wind          = wind

any clues?
