misd-agin. It looks to me you are quoting normal glide figures, not all-engine-out figures which is what this thread is about. I might be wrong though. Can you confirm either way please?
galaxy flyer and others, there is no need to complicate (and subsequently not answer) the question with a million "but what if" scenarios that would adversely affect the drag qualities of what's left of the aeroplane. A simple engine flame-out will do thanks.
So I asked a simple question. What contribution to the glide performance do engines operating at flight idle have? What happens to the glide performance when the energy equivalent to 200-400 kg/h per engine is taken out of the equation?
I've expressed my ideas based on a hunch really, and wanted some confirmation that my reasoning was at least sound, if not strictly scientific.
Thanks for the replies so far.
