As announced by Graham Eccleston in an Orbx forum post last week his team have released an update for the AU/NZ AI pack with a bunch of P3D v2 compatibility improvements..

Here is a small update to the FTX AU AI traffic pack for Prepar3D V2. This update is limited to a cleanup script to delete the temporary files included in the earlier versions of this pack to cater for the issues with the HTAI Cessna aircraft in P3D V2. It also includes updates to the Control Panel plus the User Guide to be consistent with the changes contained in this patch. There is no new content included in this update and it is now in line with the most recent FTX AU AI Traffic pack released for FSX
