James,

First off, (it was late last night) let me correct my statement.  I am 
referring to the generic autopilot, not the course manager.  It does not seem 
to have any correlation to the course manager.

I'm finding it more specific.
Example A -
Aircraft : AD-6, F-4N, A-3D, RA-5
Airport : KGFL
Runway : 30
Heading bug : 130.94
True Heading : unreadable due to it flipping.  Click on the box and sometimes I 
will get 116.835, the other times I can get 344.532
Alt Hold : 18 - This is unchangable
Speed Hold : 120 - This is unchangable

I'm not flying each model right now, but previously all other parameters would 
work (wing leveler, pitch hold, VS hold, etc)
So I was thinking it was a jsb relation, but then I tried these same aircraft 
at KPBG and they work fine.  Can it be a navaid issue?

The issue will carry forward with you.  If you change airports using the 
"location" menu, the issue will stay, but the numbers will change.
If you quit and restart at another airport (that doesn't have an issue such as 
KPBG) then it works fine.

I just tried Gary "Buckaroo" Neeley's new MD-81, which is a very good yasim fdm 
but has no other interference as a test bed, and it displays the same data 
issues in Autopilot.

Seems like random airports where this shows up.  KBGR and KPBG it works fine, 
but KALB it's there.
KALB
Aircraft : dh2w, MD-81, 777-200ER
Heading bug : 114.421
True Heading : 265.842, or 100.613, depending when you click the box.
Alt Hold : 18, unchangable
Speed hold : 120, unchangable

So that's interesting - the Beaver and MD-81 has no autopilot, and while I 
don't fly the 777, I assume it does(?). 

Hope that helps,
Peter
