How Long Does It Take To Fuel An A380?

Thu Nov 06, 2008 6:37 pm

With the A380 being such a big plane, how long does it usually take to fuel it up for a flight? Does it require more than one fuel truck? How would it compare to fueling a 747, a 777, or an A340?

Thanks,

Well I suppose it depends on how far it is going.
Work it out. On a B744, with two dispensers and 4 hoses, fuel will go in at about 7000 litres/min at the start. I fill a B744 from 8000kg to 130000kg in about 40 mins. It is never going to be a problem. The cleaners can't work that fast.

It's been a long time since I was a fueler. I'm sure it would be well less than an hour - as TS said, the ground crew servicing the rest of the plane will need more time than the fueler will. Back in the day, I used to fuel DL # 683.....CVG-LAX. It was a 727-200 with an aux tank. If I can remember correctly, about 66,000lbs of fuel. My truck was a 10,000 gallon truck, used to take between 8,000 and 9,000 gallons. 2 hoses and I could turn it in about 25 minutes - from time I pulled up, to time I left. If it came in with an inop fuel guage, they would give extra time, but you really didn't need it. Do a pitch/roll.....find the fuel level with the drip-stick......look at the chart......and put in the difference of what is required and what you have in the tank. Of coures, if you were topping the tank off, just keep fuelling until the valve shuts.

How often would you do that?

I think the only time when fueling is the bottle neck is when the stop is for fueling only. An example is charter flights from Europe to Thailand that stop in the Middle East or India for fuel. Pax stay on the plane, no catering, no cleaning. Just fuel.

Pretty often. The loading schedule for most airliners has you fill (basically) from the outside inward, rather than evenly.

So, you'll usually fill the wing tanks completely before you add anything to the center. Given that the center tank is usually the largest one, that means you can't go all that far without completely filling the wing tanks.

Off the top of my head the full wing tank range of aircraft I have fuelled is
B737 2.5 hrs
A320 4 hrs
B757 2.5 hrs
B767 8 hrs (maybe a bit less, it was a long time ago I filled the wings)
B777 8 hrs
B744 9.5 hrs

Ranges over this you start on the centre tank.
On the B744, you start using the stab tank at about 11.5 hrs (before the centre is full).

Man, that was a long time ago....1984/85. I used to fuel that flt. every nite. It was my last plane every nite. Pull up with a full truck, fuel 683, go fill my truck back up, and go home. As for the sequense of filling the tanks, on the 727-200, you put fuel in L/C/R evenly. All 3 had to be within a certain tolerance.....maybe 1000 lbs.? (I forget) until the wings were full. Also, the planes that DL used on that flight also had aft aux tanks. We would open the valve (in a separate panel near the wing root) once the wing tanks were full. That tank was a bladder tank, and the fuel line to it from the single point manifold was a relatively small diameter. Once the wings were full, and we would open the aft. aux., the center tank would fill pretty quick. When we would get down to about 10,000 lbs. to go, we would disconnect 1 hose. By the time a helper would get that hose wound up, the plane was just about full.

Thanks for bringing these memories back to me....I can't believe how much of that I remember. LOL, I was just a pup back then, but it seems like only yesterday. BTW....the aircraft that DL brought into CVG for regularly scheduled service back then were: 727-200, 737-200, 757-200, 767-200, DC-8-71, and DC-9-32. I used to fuel the DC-8 every day too. Notice no L-1011's. They only came in when there was an equipment change - none on a regular schedule. I think that DL had about 100 flts. per day then, and OH maybe about the same.
