Bendix/King KI 525A Horizontal Situation Indicator (HSI) out of sync

[meh1951]

If I am headed 360 deg and use the heading beg to turn to 260deg it actually gets out of sync and ends up at 265 deg or so. This has been going on since switching to FS2024. You can kind of seen it happen..

Are you saying that the headig bug moves on its own, after you set it? I’ve never had that happened, from what I can recall. Have you checked if you have any conflicting control bindings?

Unless there is something going on locally, as ploodovic suggestions, I'm reasonably sure the variable is not changing value, so I'm inclined to believe that you're just looking at the parallax effect of the 3D gauge. They can be surprisingly deep in the real aircraft! I actually tend to underrepresent the depth in my aircraft for fear of complaints about excessive parallax.

[meh1951]

There is no conflicts. I'm pretty sure I've reported this before. This has been go on since the release.
Please try it and see for yourself.

@meh1951 I have examined the Bonanza under the exact conditions as your original post. MSFS 2024, PMS50 GTN, turning from 360 to 075. I monitored the underlying variable and the animation code while the autopilot executed the turn. Such measures were ultimately unnecessary, as the heading bug position remains rock solid on the intended heading as long as your view is perpendicular to the HSI card. As I said, this is merely a parallax effect.

Oh, I misunderstood the situation. Apologies for the confusion.

If you turn on Instrument Description Tooltips, it will show you the exact values of the instrument.

When viewed from normal pilot angle, it looks like the heading bug is set to 80°, but the tooltip tells a different story.

When viewed straight from the front, the perspective shifts, no more parallax effect.

OK then, I guess it's my bad. Sorry for this 76 year old's misunderstanding.
