Flight Nav vs Inflight Map

Most airplanes don't have inflight information systems. If you ever wonder where you are, your altitude, ground speed, direct distance to your destination in Miles, Nautical Miles and Kilometers, and how many hours you still have to get there, this app will help you! 
 
Flight Nav uses GPS signals while in Airplane Mode to display your position, estimated distance, and time to your destination. You can record your flight and later share it as a GPX file. This option will consume more battery as it will operate even while you are not using your device. Other features include a "Don't sleep" feature to keep the screen on. 

GPS reception from within an aircraft can sometimes be poor. Best results are with window seats, or close to them, and you might have to wait longer to get results than you would while on the ground. What this means is that you might not get any signal at all, and the app might not work as expected every time, especially if you're sitting in the middle seats of a wide body airplane. Map detail will not be available at every zoom level - since you will be running offline - and you should use the app before flying, while still connected, in order to cache map information. 

You should only use your device when allowed by the cabin crew - Please, pay attention to the specific instructions regarding mobile devices. If you have doubts about using your device, even with Airplane Mode enabled, please consult the cabin crew.

 You can add your own destinations by long pressing the map on the location you want. Continued use of GPS can dramatically decrease battery life.

This app is intended for airline passengers who wants to see precise position of airplane on moving map in-flight. It does not require Internet connection to operate and indicates following flight parameters: * Ground speed (mph or km/h) * Altitude measured by GPS (ft or m) * Barometric altitude i.e. altitude associated with air pressure inside the cabin (ft or m) if supported by iOS device * Distance from departure / to destination airports (mi or km) * Time since departure (after takeoff detected) and to destination (calculated) While offline operation is primary use case an Internet access adding weather information for selected origin/destination, access to list of flights on FlightAware web site, weather radar and more detailed online maps. Recorded track can be exported in popular GPX format for review in Google Earth or similar geo applications later on. Imperial and metric units are both supported. It is also possible to make a text notes during the flight and review them later on. Notes are injected into the exported GPX file or can be exported separately as TXT file. More and more airlines prefer not to install seatback IFE on airplanes. That's causing lack of awareness important for many passengers. This app is trying to fix it using latest technologies available on iPhones. Few additional facts: * In order to work properly app requires access to internal GPS.  * Window seat is highly recommended.  * It may take 30-60 seconds to get initial GPS fix.  * Time since departure is most precise if app running while airplane taking off. At that time iPhone should be in airplane mode.
