Or could be the approach to 4L and 4R being dependent on there being no ship of mast height greater than 150 feet or so present in the channel or at the adjacent container port. With a ship in the channel it means either a seriously displaced threshold or an 8-12 percent approach path over the obstacle to the threshold. - Bob -- R.W.
