I posted this in Bugs but I never seem to get any action there. Is someone able to try this on the B747? Here is the copy/paste from the bug post:
The last three times I have done an ILS approach to KORD Runway 28C flying the B747-8i, the approach autopilot slowly directs me to Runway 28R. I have the runway landing assist turned on that shows the decent boxes clearly going to 28C, but I see the plane slowly drift to the right and off of the path directly to 28R. Can anyone give this a try? I think each approach I have done to 28C starts at VOGLR navpoint so try that one please!
