Effect conditionnings in FS9

Hi all, I'm experimenting with effects in general and sound effects in particular, the latter according to PaavoP's procedure at http://forums.avsim.net/dcboard.php?az=sho...ing_type=search (last post)Question1- In general: Is it possible to add a NAV1/NAV2/COM/ADF conditional display to an effect? If so, how should those parameters be written? Something like NAV2=116.5,116.5 or ADF=430,430? (just a guess)Question 2- Relative to sound effect: Is it possible to vary the audio level relative to the distance between user and effect source. Highest near the source and fainting when moving away. A similar action that occurs when moving closer/away an active AI in FS.Thanks for any help,Hugo
