improve refueling time
I think it takes up 30 minutes to completely refuel a Boeing737. The maximum rate is 1,136 ltr/min. The 737 can hold around 23000 liters. For an Airbus A380 that would take a good deal more time. But if the fuel pipe coupling with the tank could be enlarged, then that would presumably allow the refueling time to be reduced, which would improve turn-around times....
