ParkPosGenerator generates the exact parking positions of all your airports in P3D and FSX. These positions are input for my PSXSeeconTraffic program
The latest version, August 7, 2017, for Windows 7 or later is available here.
Is it free?
Yes and no, it may be used free of charge. However, "free of charge" must not be confused with "completely free". ParkPosGenerator is copyrighted software, not free software. There are restrictions on distribution and use; see the EULA file for details. A major restriction is that it is for non-commercial use only!
