I saw a small blurb in the GSX manual that GSX doesn't offer a GPU (Ground Power Unit) but some 3rd party planes do along with chocks and such
I wish it were possible to offer GPU, chocks, lav/water servicing native to GSX rather than third party
and of course I'd like to see it work with cargo (FedEx, UPS, Cougar cargo, etc)
and what about military? F-18, F-16s, C-17s C-5, B-52, etc.
