What is the actual size difference between the 7E7 and a 747. Is it actually bigger and longer? Does it hold more passangers?
The gap is quite large, the 7E7 is only a 757/767, A300/A310, and A330 replacement. When the 7E7 joins Boeing's wide-body lineup, the 7E7 will be the baby with the 747 being the largest and the 777 between them.
The 7E7 will most likely be offered in two lengths, but three versions. The Base will provide a replacement for 767s and A300s, the Short Range will replace A310s and 757s, and the Stretch will compete with the A330 and probably open new markets that haven't been tapped-
Base 7E7- 200 pax in 3 class; 182 ft; 7,800nm
Short Range 7E7- 300 pax in 1 class; 182 ft; 3,500nm
Stretch 7E7- 250 pax in 3 class; 202 ft; 8,300nm
Since you asked about the 747, here's a comparison-
747-400ER- 416 pax in 3 class; 231 ft; 7,670nm
777-300ER- 365 pax in 3 class; 242 ft; 7,705nm
777-200ER- 301 pax in 3 class; 209 ft; 7,730nm
Hope that helps, if you would like to compare these numbers to Airbus aircraft this should be useful- http://www.airbus.com
I can't wait for this plane!
