Have you used the new Navigraph plugin for Mfs2020?
Well, Foreflight in that same way would be THE app to use. I’m my opinion, of course.
Instead of tapping the ipad, interact in VR with your mouse on every aspect of the app.
I’ve tried Foreflight in VR using OVR Toolkit (?) I think that’s the name of the app.
It’s all fun and games until you need to tap for info anywhere in the map or menus.
Once I tried, and ending up tapping one of my cats instead 
He was happy though.
Anyway, if only for having other options right?
They are big fans of Flight Sims, indeed.
But allocating resources for this… perhaps if more people request it or Microsoft approached them, who knows.
I have the feeling we will see this app in native VR in the future, I’m an optimist.
