Fac6,

Take all that and do something useful with it why don't you? Join the GC and get some work done instead of wasting your time here on Pprune with all of us simple-minded blowhards.

Will be 4 a day soon I believe.

It's nothing to do with noise, it's all about eu carbon emissions and fuel burn!

What is the status of the LHR noise regulations ? I “heard” the noise regulations that were due to come in were deferred as BA/VS said they will not stop operating 744s for some time yet.

FRA-EZE is only around 6300 nm, which is like a eastbound HKG-LAX. They have said it will not be a problem over their route network, which is a lot short of 8000 nm.

Lufthansa operate their 747-8Is with only 386 seats, very little capacity change over their latest 744s configuration.

Might be very little capacity change BUT a big fuel req drop :ok:

-400 wing fuel = 163T
-8 wing fuel = 184T (yes the -8 has an extra 21Ts in the wings)

Even without the stab fuel the -8 holds 11T more fuel than a fully fueled -400 and burns at least 15% less.

Comparing the 8F to the 400ERF, the 8F looks like it burns a small amount more, not 15% less.

Well I can say that according to the DCP 747 that on an ICN HKG sector the 8F burns about 4 tonnes less than a 400 ERF. That would be around 15% less for a bigger payload :ok:

I wouldn't use short haul metrics to judge the -8F. Long haul is what it is built for. In that mission, it is easily carrying the extra 16% cargo volume and the increased weight of the aircraft for the same or better burn than the -400ERF. This before two engine tweaks over the next couple years and a rumor of more performance from the wing after some flight control changes. Also, the airplane will only get lighter as the production process is refined.

To me, it looks very likely that the ten -8 options CX has will be firmed as Intercontinental orders this year. Yet you never know what rabbit Airbus will pull out of the hat to sell the 380.

The promise of fewer cracks in the wings of CX bound 380s perhaps....:E:E:E:D

Based on what? I've flown it a bunch and the thing makes gas every sector. CFP will eventually be adjusted I'm sure, but I think we are are carrying at least 20T more freight for the same fuel burn as an ERF. That's what I'm seeing anyway.

Based on Pprune bulls***:D

The 8 seems a very impressive piece of kit :ok:

Enjoy.
