I have been reading that the MEW of the B787-8 has been constantly improving since the first aircraft. On the Boeing website the OEW is listed at 117.7T. Does anyone know whether this would be consistent with the OEW of the aircraft that from 9T overweight, or is consistent with an aircraft which I think is now closer to its weight target?

The Delivered Empty Weight (a Boeing term for Basic Empty Weight) is typically around 252,00# The Operational Empty Weight of course varies with the airline configuration but should be somewhere around 259,800 with flight and cabin crew, Residual fluids including say 110 USG water and 1300# pax catering & carts. Hope that helps.

Quoting BravoOne (Reply 1): The Delivered Empty Weight (a Boeing term for Basic Empty Weight) is typically around 252,00#
This is not a term that Boeing use in the General Characteristics section of their ACAP sheets.
Quoting mpvincent (Reply 3): any suggested ranges on what a heaviest spec would be for a 224-seat config? +3T?
Since the published OEW is based on 242-seat config. wouldn't a 224-seat config. be lighter? The weight per seat in Y is not very much, probably about 25kg.
Go to ahmthy.com where TK explains in detail what is included in the OEW and what is added to get to the DOW . They are probably fairly typical in this respect for most airlines except the premium carriers who probably load more catering.
