I have a considerable number of files for AI aircraft for FS2002, can I use these in FS2004?

Almost all AI aircraft will need an update for their flight dynamics. MS changed the way some of the values are used - most notably changing the cruise speed from KIAS to KTAS. This often results in FS2002 AI aircraft flying above FL300 with the gear and flaps extended - possibly even stalling.Once you update the flight dynamics - almost all are fine.Traffic Tools 2.0.2.0 will open FS2002 traffic files - decompile them - and then your can start it again and compile them as FS2004 traffic files. It's very smart.
