Slight slip in terminology - sorry. Full 26k takeoff thrust is less than the full forward stop, but full 27k Max rated thrust is at the forward stop ref FCOM 2 7.20.4; what isn't obvious to me either from FCOMs or my FMC guide is whether full GA thrust is 26k or 27k - from thrust lever position at GA thrust I would assume it is 26k?
Hopefully the CVR evidence will indicate whether a Windshear or a normal go-around was intended.
