Unfortunately this isn’t something the MS/Asobo developers can do anything about. You would need to reach out to the third parties that made the aircraft and have them add the correct performance file to the package.
In my case, there is no data available from Carenado for the CT210N or from FSReborn for the Piper M600 SLS.
I know I can find the data online, but it isn’t saved correctly, and even after entering and saving the data, the message “Performance data not available” continues to appear.
Thank you for this. Yes I found these documents too in web, but I mean if I save the filled out form in the ms web planner than the data will not getting saved. Always „performance data not available“.
They’re referring to planner.flightsimulator.com and the Planner app in the sim - both of which get their data from a file within the aircraft. It can’t simply be user-edited.
Unfortunately most default/first party aircraft don’t even have this data at this point, so I’m not sure many 3rd party developers will bother going through the effort of creating it either.
No, what I’m saying is that the data must be input by the developer (or a very complex JSON file must be submitted by the user). It’s not something easily/intended to be done by the user themselves. The only practical answer is to petition the developer(s) that made your aircraft and ask them to update the aircraft to include the appropriate data.
They likely misunderstood the question - what they probably thought you were asking for was an upload of the performance charts and other data from the real-world aircraft’s POH, and since they don’t license their aircraft with the manufacturers, they’d be unable to provide this. If you reply, you should include a link to planner.flightsimulator.com or direct them to the Working Title team for guidance on including adequate performance data for their aircraft.
