On turnaround flights, VNAV does not work

[Stationair]

Hello guys! 

After a turnaround, and after departing, VNAV does not engage neither V/S, ALT HOLD modes, and it causes a funny behaviour in the MCP speed window.

Interesting! ...and hard to reproduce, of course - with your report being the only one for this so far (after many many years and many many users ;-)).

If this happens repeatedly, you can "reboot gizmo" while on the ground, that should really clear all variables and reset the plane as if you just booted X-Plane.

Cheers, Jan

Hi Litjan, thanks for your answer.

I've been rebooting Gizmo after turnaround flights since I've got the FMC error, and it's been happening anyway

Cheers!

Hmm, is this only happening on a certain path (i.e. the same airport and SID) or does it happen a lot and in various scenarios?

If you could provide reconstruction steps and a log.txt, that would be helpful to find out what the bug is - because it is clearly that, not user error. The speed window should never show these out-of-bounds values, no matter what the pilot does.

Thanks, Jan
