The Cessna 152 Attitude indicator does not seem to move the attitude bars position. I've found this on both the standard 152 indicator and the panel one (with the purple background)
The Cessna 172 indicator works as expected and if I look at the code behind I can see the 172 subscribes to the ATTITUDE BARS POSITION variable, whereas the 152 version does not.
I don't know enough about the coding to fix the 152 one, but should this not be fixed in the base instrument anyway?
