Feb. 14th, 2022, © Leeham News: Boeing Commercial Aircraft (BCA) CEO Stan Deal announced that the company was working on a high gross weight (HGW) variant of the 787-10 Dreamliner.

LNA later revealed that the maximum takeoff weight (MTOW) increase would also be available on the 787-9. The goal of the increased MTOW is to make the 787-10 more competitive against the A350-900, which currently has a significantly higher nominal range: 6,430 nm vs. 8,100 nm. The 787-10 HGW range should match that of the 777-200ER.

The 787-10 HGW targets replacing larger, older-generation, twin-aisle aircraft still in service, notably the 777-200ER and 777-300ER. Boeing's primary goal is to prevent customers from ordering the Airbus A350-900 due to a lack of payload-range for the 787-10.

Boeing paused developing the 777-8 around 2.5 years ago, and it is not clear whether the variant will ever enter service. Therefore, without the 787-10 HGW, there would be a sizable seat gap between the 787-9 (290) and 777-9 (414) in the American OEM's long-range twin-aisle offering. Both A350 variants are in that seat gap.

The arrival on the market of the 787-10 HGW has the potential to affect sales opportunities for the A350 and the 777X. LNA analyses the potential replacement market for long-range aircraft seating 300 or more passengers in this context.

  • Large twin-aisle replacement market;
  • 787-10 HGW potential customers;
  • The airlines unlikely to order the 787-10 HGW.
