Re: Why Boeing hasn’t made a ULH Version of the 787

To make a real ULH aircraft, the 787 would need extra tankage - another 10 tons or so. MTOW bump to 260 would increase payload, but actually decrease range at the extremes of the envelope. The 788 ULH version would be great - the OEW is almost 10 tons less and it burns ~5% less fuel than the 789. Gi...
