A portable electronic device containing an embedded application provides real-time flight status information to users traveling on an airplane while the device is operating in airplane mode with no wireless connectivity. Before departure, the application downloads flight plan route information, digital map data, and other information of interest to the user. The airplane's in-flight entertainment system repeatedly announces the airplane's latest position on an audio channel. Users can enter position coordinates into the application manually or plug an audio cable into both the armrest of his chair and the application's smart-phone, tablet, net-book or laptop computer. The application recognizes position information from the user or the announcements and then correlates the airplane's in-flight position to saved map coordinates and displays a moving map image based on the flight's progress. The image includes flight status and links to saved information such as images of points of interest.
