I've been trying to isolate a gauge causing the heading bug to increment in 10 degree intervals which is a pretty common problem in FSX.

The plane is the Captain Sim 727. I have all the gauges commented out except the HSI, but the heading bug knob is in a separate gauge.

Does anybody know which gauge the knob is in?

I don't know the answer to your question, but you are right, it is a fairly common problem with FSX aircraft, and the good thing is, it only seems to happen when you're on the ground.  As soon as you're in the air, the heading bug/knob should work normally.

What I do when I'm on the runway, ready for takeoff, I turn the knob to get the heading bug as close to the runway heading as possible.  Then, once I take off, I turn the knob to the proper heading.

Oh, thanks for that. I'll give it a try. It's a beautifully modelled plane, but a little rough around the edges.

Have you tried using FSUIPC4? There is a setting called "Fix control acceleration" that helps precisely with that.

It is a beautifully modeled airplane, I own it as well and I really enjoy flying it.  I actually have found flight dynamics mods for the Captain Sim 727-100 and the 727-200 which makes flying them even more fun.  If you're interested, I can give you a link to download them from my cloud, just let me know.  Captain Sim planes are nice when it comes to systems but the flight dynamics of their aircraft are very inaccurate.

I've got my heading bug fixed, thanks for your advice, but it's still got an offset error of about 13 degrees. Say the GPS says I'm tracking 342° then the HSI says that I'm heading in a 355° direction.

It's not a big deal, it just takes a quick mental correction. Do you see this in your 727? Does your mod fix this?

Otherwise, it's virtually faultless and I'm delighted with it.

I'm glad you took my advice, at least it's a workaround that helps make it so it's not a huge deal.

If you want to try something fun, try to learn how to navigate using the CIVA navigation unit instead of the GPS.  That is what the real aircraft used for navigation back in the day.  The Captain Sim 727 comes with one.  It's actually not that difficult to use.  I used an AI chat bot to teach me how to use it.

The mod I mentioned just improves flight dynamics (flight model) so that the plane flies closer to the real thing.  It does not fix anything else, just the flight dynamics.  I don't buy many Captain Sim aircraft because the flight dynamics are very unrealistic and do not fly like the real aircraft do.

Here's the link to them anyway if you want to try them: https://mega.nz/folder/y9tGWCIZ#ELLHwLlYfjC3Ep6htbxHpg

In that folder there's FDE (flight dynamics) mods I found for the Captain Sim 727-100, 727-200, 737-200 and the 757.

The package for the 737-200 is actually a total overhaul of the airplane, it fixes a lot more than just the flight dynamics.

These packages were difficult to find on the internet which is why I am sharing them instead of giving you the original links.  I'm not sure if I could even find them again if I tried, they were really buried on the web.
