Feature Request: New export option: Set Flight Plan in MSFS

[fredrikhr]

I'd like to propose a new feature in the File-menu that allows the export of the Flight Plan directly into the currently active session in MSFS. Little Navmap has already the ability to export the flight plan as an MSFS compatible .pln file.

In contrast to FSX, the only place in MSFS where you can load a .pln is in the Flight setup menu before the flight is started. This makes it impossible to flight multi-leg flights in the simulator without ending the current flight and starting a new one (or changing you flight plan mid-flight for diversion).

Obviously this is a shortcoming of MSFS and not a fault in Little Navmap. However, SimConnect has the API SimConnect_FlightPlanLoad that takes a path to an .pln file. If I read the API specification correctly and judging from the original functionality in FSX this should allow programs to load a new flight plan into the sim while it is active. The proof that this theoretically should work can be seen in some planes that use the G1000 cockpit which allows for Flight plan changes mid-flight and these changes are then picked up by the sim (however, planes like e.g. the ATR do not have this functionality). There are even specific ATC message options in such an event that say "<Callsign> would like to change IFR flight plan to <Destination>".

I propose a new menu item Send Flight Plan to MSFS 2020 in the File-menu below the currently existing Export Flight Plan as MSFS 2020 PLN. When clicked, this menu item should export the Flight Plan into a temporary .pln file and subsequently call the SimConnect API mentioned above.
