Wow, at YKZ most of the fuelings are nozzle fuelings with like 100-300 litres per side. The odd singlepoint bizjet with a few hundred more. I am bigger airports have faster singlepoint nozzles/hoses but I can't picture having to do a large jet with our equip. The tank would be low if not empty by the time we finished 1 737. How long does it usually take to fuel a 747 (i assume they have both wings fueling at the same time)
Support the beer and soda can industry, recycle old airplanes!

Quoting JAGflyer (Reply 4): How long does it usually take to fuel a 747 (i assume they have both wings fueling at the same time)
G'day JAGflyer . I used to work at the international terminal at SYD. The heaviest fuel loads were for the 744(non ER) aircraft doing Trans-Pacific flights to LAX. In these situations, the final fuel figure was often as high as 176 tonnes depending on the specific gravity for the day. The aircraft usually had about 15 tonnes of fuel aboard, so the uplift was about 160 tonnes. IIRC, this would take about 40-45 minutes with 2 trucks.
The best part of these tasks was if you could manage to get the final fuel load not more than 100 -200 kg above what the pilots wanted. Too much more was no good as they were often at MTOW, but an extra 100 -200kg would be burnt during taxi putting them right on MTOW upon line up to the runway. It was even better if the discrepancy was less than 100 kg as well !
It was just amazing how low the wing bent down with that much fuel. The inlets of the outboard engines were no higher than the inboards. Add a full load of passengers and baggage and the landing gear struts would have only an inch or so of chrome showing. This meant that the engine inlets were only about 3 -4 feet off the ground! You could almost touch the wingtips if you jumped hard enough.

Quoting JAGflyer (Reply 8): The first time I watched an MU2 being fueled I was told to watch the wings to see what happens. Since they are very highwinged you can see the weight of the fuel bending them down.
Even on common commercial Aircraft ie B737/757s.Its cautioned not to place the Cocks touching the wheels & not place Trestles/Equipment below wings as the added fuel weight can cause the Aircraft to drop lower on the Struts.
