Product(s): FSUIPC5

Current Status: Works

Current Status: Works

Statement: “You should have no issues with forward compatibility in any PMDG product currently working in Prepar3D v4.3.  It is very important to us that we not obstruct your forward progress in minor version updates of Prepar3D, so we do not inhibit the airplane from running with a new version.  Such inhibitors are untidy and rather unfriendly- and haven’t proven to be necessary in any regard- so if you want to move to P3D v4.4 you won’t find any problems on our end.”
