Ok - so we better ask SimBrief !? Well then.. I must admit I do not know what it takes to implement this or that into this or that software and/or Website. But is there a chance that it will come to SimBrief support (in the next few month)? To be honest, years ago I had to choose between Navigraph and Aerosoft and I choose Navigraph - not because of their pricing, it was because of what they support. The various aircraft, the various Sims and last but not least the support for SimBrief. I am flying X-Plane on a Mac (yes yes I know all the cons :-)) and I still will be doing so. And I am flying online. As far as I know PFPX is not working on Mac. I know I belong to a minority in the FlightSim-Community - but we are here and growing!
Well, it is time for Aerosoft to reconsider... Now, that Navigraph canceled their "FMS Data only" Subscription and forced all customers to the highly-priced "ultimate subscription" (wich is around 3-4 times more expensive) it might be that customers switch over to Aerosoft. As mentioned above SimBrief has become very popular throughout the community because it easy to use and supports various Flightplan-formats for the different Sims and Aircraft. The mentioned "protective measure" for their PFPX is so old school. Nowadays we have different Sims on the Market and even virtual Pilots on Mac become more and more and running X-Plane (wich is cross-platform as you all know). So it might be a good (and clever) idea to open up their support for other Planning-tools and other Sims on various OS-es.
