How can I set aircraft location in a gau file?

Hi,I want to set various user aircraft variables in FS through a GAU file. But, I cannot figure out how to set variables like latitude, longitude, altitude and so on. Is this possible and how? I couldn't find any suitable key events. I know this is possible through FSU, but I would like to know if there is an internal (and possibly faster) way of doing this?The goal is to map a user aircraft location to a selected AI aircraft and I have already managed to read AI aircraft location via the ITrafficInfo interface.Regards,Arnt Helge Haaland
