Ciao Umberto
I was taking my 747-8 for a flight during the weekend and needed around 140t of fuel. As I had around 10t in the tanks when asking for fueling, I expected it to last a bit. Since I was doing a cargo flight and therefore parked on a outside stand, more than 1 fuel truck did arrive. However after over 1 hour my fueling was still not finished (next truck is on it's way) and cargo loading has not even started yet. Since my slot time was coming, I had to disable GSX and, reanable it and just continue with the pushback.
I do not think that there is a mistake in GSX, I am just curious how many fuel trucks I actually would have needed to refuel the aircraft? Could I "tricked" to situation with setting the parkposition to ground fueled? I assume that would be faster?
Thanks for your explanation.
