Our on board computer calculates the airplanes location during the flight. If it flies out of the WiFi transmission range and disconnects, the autopilot will take control and guide the airplane back "home", and land it within 50 meters proximity.
However, the changes in wind factor and additional inaccuracies, may divert the airplane from it's course.
Important tip: Every time the airplane passes close to "home" it calibrates it's location. Passing close to "home" occasionally will improve the return home route.
