Just a crappy photo of refuelling the mighty 777-300 these are relatively new build aircraft .........only a couple of years old . The centre tank fuel system has been modified on all new 777s so that they fuel much quicker.The 144,776 ltrs was put on in 49 minutes .......really good going compared to 90 minutes for the older 777s . For those interested the fuel uplift in kilograms was 125:600 kgs . The photo also gives you a fair idea of just how big the GE90 engine is compared to the hydrant cart .

I believe the RR Trent can fit the fuselage of a 737 through it.

No that'd be a bird strike you wouldn't walk away from.

How long does it take to put your 200t of go-juice on the Super-Pig, Knotty?

Not just the Trent but the GE 90 as well salty...

I think that's right Salty ,I have heard that in the past .

The super pig takes around 1hr 30 mins with 2 trucks for 200 t, or 2 hrs with one truck . Once you get a bit on , say 120t ....two trucks tend to fight each other .......as in flow rates .only around 2200 ltrs pre min ...per truck ...so you are better off , pissing the other truck off . The flow rate picks up , and as you know the trim tank is very slow ......so there is no need for the second truck at that stage . All this depends on the time of day too , as the more hydrant trucks hooked up and pumping , the ground pressure can drop down to as low as 400 kpa as opposed to 800-1000 kpa normally . The hydrant system at MEL is only good for about 420 litres a second to Tarmac before it has a heart attack . With some airlines the biggest problem is finding an engineer to give you a final fuel figure ........we spend a lot of time waiting around for final fuel loads . Sometimes aircraft are delayed because of this ......if we sit for 30 mins not pumping and then they come out 20 mins before departure wanting another 30 t ......well it just dose'nt happen , and then they try and hit us with a delay

And here's me in the past asking for 30 litres of Avgas for the Laser in the past - why do I feel so inadequate now ?

Does kinda put things in perspective! Great post Knotty.

Don't worry Adam , we all have to start somewhere .30 ltrs .......I wouldn't even bother getting in the truck for that How would you go with some of Salty's uplifts .......on the 380 ....240.0000 ltrs ....... To high 250s is not uncommon . Glad I'm not paying for it .

Knotty I feel your pain. we didnt have 777 when I was fueling, but that cursed 757 was a real killer. the wing tanks 6500kilos each and the centre 18500kilos were designed to fill at the same rate. so it would take 40 minutes just to fill the wings up. not so much fun being on a lift 15 feet in the air with a -40c wind blowing.

UPS used to try to burn us with the late final fuel load crap. they were a massive pain in the ass to deal with.

I'm hearing ya Dylan re 757 . Luck would have it that we don't do many 757s in this part of the world . The only one we do occasionally is the New Zealand Air Force one . I love the 757 ......but when we fuel them it is a slow process.
