I’m an FSX and XPLANER from the beginning…Now here we are at 2020…how do i get fore flight and air manager to work on my Ipads I have in my home cockpit…They worked perfectly in XP…That is how I fly in windowed mode showing no instruments on my screens. Anyone with answers are appreciated****** …THANKS…K

I don’t know about AirManager, but Foreflight is working very well for me. On the Foreflight website you’ll find the instructions.
