This always depends on what you have installed. As Mathijs explained, you can use 2 providers at the same time and if you point the 2nd database to the 2nd provider and this one is outdated, you might end up with different dates.
, help me understand...are you saying the A/C will be linked to an application that runs parallel to the simulator (similar to Fenix A320) that will have to be launched to use the A/C and/or certain features? I'm good with that if so...just wasn't expecting. Or perhaps I misunderstood your comment?
I have one question. Is it normal that the second nav date has a different expiration Date than the first on, as they in this case are bouth Cycle 2305 so they should be the same timeframe.
Sorry, but no. This part of the product will be updated to the last minute. That is why it will be a server-based as well. That way we can do multiple updates a day when the first comments come in. Also makes it a perfect system for tablet or laptop use. It also solves a lot of the issues with Xbox/Cloud and Marketplace copies that can't have manuals.
Same format as for the P3D versions.
A quick note on the nav database inside MSFS. That database currently uses a very different system than NavDataPro and Navigraph, and it is virtually impossible to use both in one DLC. It would mean having two very different sets of code for every part of the system that needs the navdata. As one developer described it, as different as 'an apple to a great white shark'. That is not to say it is worse (though we could use some regular updates); it is just a completely different system.
