Hi!
I was wondering how much fuel you take when you fly with a 747. When you fly a short flight of say 3 hours or so, do you fill up the whole plane or do you just give it a 50% or so?
I mean, there should be a trade-off between getting cheap fuel or carrying the extra load – is this taken into account?
regards,
Castor

LAX to HKG in the winter, we take approx 170 tonnes of fuel and land with around 11 tonnes.

OK from a drivers point of view.
1. Trip Fuel, ie that needed for the planned route based on the predicted aircraft weight.
2. Contingency fuel or route reserve, can be 3-5% of the above dependent on company policy. This is if you don’t get the planned flight level and hence predicted fuel burn. Also unplanned re-routes.
3. Alternate Fuel.
4. Final Fuel, that need for 30 mins holding at alternate at 1500′
5. Taxi and Apu fuel.
6.Extra fuel. For holding and delays, tanking. Tanking is where it is cheaper to take fuel with you, even though additional fuel is used to carry it. Because fuel at destination is much more expensive.
Most carriers use this system, with national/carrier variances on the formulas.
Hope that makes sense.

LOL, I know they are used in Japan for domestic services…but beyond that and one or two other key asian city links it seemed a strange choice based on the fact that paying for fuel in Japan is going to be fairly similar from airport to airport and I understood the question as being international benefits of fuel differences.
Compared to long haul models there are only a relatively few 747SR and 400D models flying.
Did you also know that the 400D can be altered to the full long haul model at a certain point in life as it is more likely to reach its cycle limit than flying hour limit? So changing to international status allows the hours ot eb increased and cycles reduced.

747s are used alot on trips of 3 hours and shorter espeically on domestic Japanese sectors.
