If your engine or engines suddenly quit, could you glide safely to the end of a runway? If that does happen, an iPad/iPhone app called Xavion can help point the way to a safe landing in any weather.
Xavion is the latest product from X-Plane simulator developer Austin Meyer’s Laminar Research. The company tested Xavion extensively on X-Plane and used the simulations to hone the program’s algorithms. A side benefit is that you can run Xavion on X-Plane to practice before trying it in a real airplane.
