Yes, but is vastly less efficient then a EV. So, in 10 years time planes will be one of the biggest pollutants.

Re: China Airlines 330CEO Replacement - 330NEO vs 787

Right, but my main point was that the A330NEO wouldn't be a completely new type in the sense that current A330 pilots would be able to fly both versions as far as I know, whereas the 787 would be a completely new type altogether. Whether the airlines actually choose to purchase the A330NEO, on the ...

They are never going to be payload weight limited regionally, again another useless metric for people who don’t understand the role the A330 has in their fleet.

Re: China Airlines 330CEO Replacement - 330NEO vs 787

At about 5500nm, the 78X carries ~1-2T more payload than a 251T A339, based on the competing payload-range charts on respective ACAPS. Winds are a different story, but the 78X cruises faster as well. At shorter ranges (<4000nm) the 78X carries ~12T more payload. Personally I think this is hogwash, ...

Please note that YVR/SEA-TPE block time in winter is 12:30-13:00 and in this season especially departing from North America, the A339Neo would not be able to operate this sector with a full payload. In summer season the block time is 45 minutes shorter. All this talk of long sectors is nonsense. Th...

So 93t of fuel/paylo...
