The conceptual Boeing 787-10X, a stretch of the 787-9 due for entry into service in 2013, will have seating for 320 passengers and a range capability of 6,900nm (12,600km), said Boeing Commercial Airplanes vice-president of business development Nicole Piasecki.
The aircraft would be roughly 15% bigger than the 62.8m (206ft)-long 787-9, and would have a maximum take-off weight almost equivalent to the 787-9's at 251,000kg (553,000lb) with similar structures, along with notional 76,000lb thrust (338kN) from twin General Electric GEnx or Rolls-Royce Trent 1000 engines.
"The seat mile economics on this airplane are phenomenal. They are 11% better than our estimate of the A350-900 and they are over 5% better than what the A350-1000 is today," said Piasecki, whose comments came before Airbus announced a 4,000lb increase in thrust, a maximum take-off weight increase from 298,000kg to 308,000kg, and a corresponding 400nm range boost with 350 passengers or another 4,500kg in payload.
Piasecki left the possible entry into service for the jet undefined.
