Wizo , you said the 7E7 will have 30% reduction in DOC , but compared to what ?
The direct opponent of the 7E7 is the A330, an aircraft that is already advanced.
Airbus is claiming "only" 17% reduction in DOC between the A380 and the 747-400. 8% of those are due to the engines ( which the competition will be able to get as well later ) large part of the rest is due to the size difference .(the bigger the size, the lower the DOC / ton ot pax )
Difference in airframe technology between the 2 is 35 years .
Diference in airframe between the 7E7 and the A330 is 10 years. and for the same size/pax nrs.
the numbers do not match at all... and Boeing knows it as well.
I guess the 7E7 will join the sonic cruiser. A real pity because
the 767 is not selling very well anymore, ( understatement
)and it is not good to have a single manufacturer in the end.
