At Oshkosh Redbird Flight Simulations released Cygnus, a product built by partner Bad Elf that is designed to spoof your iPad into thinking it is where your flight sim says you are instead of where you really are, allowing you to use popular navigation apps, like Jeppesen’s Mobile Flight Deck, ForeFlight’s Mobile Pro or Garmin’s Garmin Pilot as you fly the sim, allowing pilots to use their mobile device just as they would in the airplane.

in other words, very expensive solution.
