I have been giving these planes some work, first is beginning to fix the AP. I have installed my IT2 Autopilot system, and it is hooked up to the dialog, PFD, and MCP. It works decently, of course, I will tune it for the plane, so it flies even better. This thread will keep track of my improvements to the A340-313X and A340-600HGW.
The new APs are stable, and can perform full long flights (LNAV works) without crashing, spinning, loosing controls ETC. Next I will work on Autothrottle, and possibly FBW. All knobs and switches are connected and working. The IT2 Autopilot is still in development, and some internal AUTOFLIGHT systems will be tuned/changed, and these planes will receive those updates.
Regards,
