> I cannot complete the initialization process in Longitude and Hjet because the Weight and Fuel page cannot be accessed. The error occurred from one day to the next. If I deactivate the Avionic Plugins in the Navigraph hub, the input works in Longitude, but not in Hjet. Anyone else have this error?

I am experiencing this now MSFS2024 (1.7.27.0) (I haven’t been in MSFS2024 very much prior to the latest SU Update). If I remove the Navigraph Plugin G3000/G5000 (v2.3.1) I can enter the Weight and Fuel but I don’t have Simbrief integration. If I add the Simbrief EFB App, I can use that to import the flight to the G5000 via file import.

It is a bummer that this causes issues.

The issue is the Weight and Fuel button is not selectable, or when I click it, it doesn’t open the weight and fuel page. Initialization and V speeds cannot be computed.
