A js/html standalone/offline* fuelplanner with Flightgear FS interface to set/calc payload and fuel and map the flghtpath and current position of your flight remotely. Useable on nearly each device and browser.
Currently the left wing / center / right wing tanks are hardcoded. To be compatible with aircrafts that have more compartments a generic solution should be implemented.
In the init*.js there should be arrays for the name / ammount / maxammount of each tank for the wings and centered tanks.
Since the origin airport and the destination airport are not stored with their coordinates the first and the last waypoint are not congruent with the airports but with the waypints right behind/before.
