Hello,
I would like to suggest three improvements which would make GSX even better, in my opinion :-)
1) in most airports where I've flown, fuel trucks are much larger than what we see in GSX. In fact it's a tractor + a trailer, like in the attached picture. It would be nice (and realistic) to have such a model in GSX, at least for commercial aircrafts.
2) low-cost airlines such as Ryanair have very short turnaround times (25 minutes for RYR). So when they reach the gate, the fuel truck is already there and they start refuelling while deboarding the plane. It would be great if we could also ask for refuelling without needing to wait for the deboarding to complete.
3) at most airports where passengers disembark to the ground (no jetway), ground handlers install a picket near the extremity of the left wing and from that picket put lanyards to the front and rear stairs, such as on the second attachment. It makes a kind of triangle under the wing where passengers may, obviously, not go. Perhaps it's something that could be simulated on GSX as well, my only doubt is how to do it with airstairs as, if I'm right, airstairs are not considered by GSX.
I hope such improvements could be taken into account, it would be great :-)
Thanks for this amazing add-on though.
