Flight plan transfer to flight simulator and back

[albar965]

Once the flight plan changes in Navmap automatically copy it to FSX computer and call
SimConnect_FlightPlanLoad.

If a flight plan changes in the simulator load it:
SimConnect_SubscribeToSystemEvent with FlightPlanActivated parameter.

Check if this is also doable for X-Plane.

I notice this feature is from 2016 - given the release of MSFS2020, is it safe to assume support for it is planned, and not just FSX?

This even more important for MSFS but needs some time. Probably have to change the communication protocol.

Would like this option very much for MSFS2020.

So, I'm trying some naive stuff using Python-SimConnect with MSFS2020 1.9.5.0 that might save you some troubleshooting down the line. Here is my naive code:

sm = SimConnect()
print(sm.load_flight_plan("path to .pln"))
sleep(5)
sm.exit()
quit()

I'm testing with the MSFS2020 Cessna 172 G1000.

I have found a few interesting things.

1. If I load up a plane with no flight plan, and run this code, everything populates into the G1000 and everything is happy.
2. If I load a flight plan, and then attempt to load a new flight plan over the top, the CDI/PFD updates accordingly, but not the FPL in the G1000. The old waypoints remain, but none are shown as active.

In situation (2) if I delete the flight plan, I can load up a new one but the same issue persists - no waypoints displayed, no active leg.

Now, if I reload the aircraft (using developer mode), whatever the last plan I called with sm.load_flight_plan appears correctly. However, this comes with other MSFS oddities like the avionics brightness being nonadjustable (at least on the C172 G1000) [This was a mod issue].

@daheise Plenty thanks for the research. I looks like MSFS needs more time to get this stable. 😞
Quite annoying there is no way to change the flight plan without restart.

There's an issue on the MSFS forums here that can be voted on: https://forums.flightsimulator.com/t/better-support-for-simconnect-flightplanload/307388

Thanks. Voted. Will watch this.
