I have the following problem when I make longer flights over a long distance.
As an example, I am currently flying from VHHH (Hong Kong) to EDDK (Cologne/Bonn).
I have created a flight plan with Simbrief, as cruising altitude FL300. I took off and climbed to FL300, air pressure is set to STD.
I track my flights with Volanta, where the current altitude is also displayed, at the beginning of my flight this is always correct, but the higher the distance, the lower the altitude volanta shows me.
There are still 930NM to fly, but in the meantime only FL282 is displayed.
The altitude in the MSFS is still displayed as set at FL300.
Is this aproblem with the Sim or with Volanta? The problem first appeared after the air pressure bug came up.
Below as an example, you can see how the line of height decreases with distance.
