WojtekSz, for such a case of thrust deficit, deliberately accepting to let the glideslope drift over would definitely extend the gliding distance.
Not here to judge the BA38 crew as I would be more than happy to have done as well as they did, but purely aerodynamically speaking, SLFY is not wrong.
Mmmayday38, as we have the privilege to have you on board here, would you like to comment on
those words, or is it too early ?
