L/D 777 gear down with landing flap setting (?)

QUOTE
Green Dot.....interesting post.

In the descent from cruise the engines would have been at Low Idle ( Gnd idle ) until any Flap/Slat or Gear selection, then this triggers the higher Flight idle speed. END QUOTE

With flaps and gear employed, what would be the L/D of the 777 ?
Assuming no power ,could it be 18:1?
At 18:1, 600 feet would have given 10,800 feet horizontal travel (a tad over two miles). I would not have been happy trying this, though!
I use 18:1 because I read somewhere that a widebody aircraft (I forgot the type) would do that in CLEAN configuration. Putting down gear and flaps would, therefore, require some power to be applied (engine spool-up time consideration etc). How much power would be required to give a L/D of 18?
