The big question is why do you need an external app for flight planning? What features should be added to the Aerofly FS navigation which you currently need the other app for.
Im using Navigraph via iOS. I think maybe the Developer Team can make an API that can connect with Navigraph/Simbrief.
This will make our flight planning route more realistic.
And also, updated AIRAC is important to make our sim experience more realistic.
For example, WMKK (Kuala Lumpur) now have 3 runways (33 is the latest). But in the game there's only 2 runaway.
