I'm currently running KMEM just fine and thought I would look at a few other airports. KMEM is fine, but at demo KJFK and KIAH my PMDG MD-11 is floating about 500 feet above the taxiway. I have never installed any 3rd party at these airport and have doubled checked with a duplicate checker. Ground services will activate if requested.
I have read about floating GSE equipment (which I don't have), but haven't seen anyone with a floating aircraft. Any ideas?
