Hello there,
I've been looking for some time for an explanation as to what the six (or was it eight) wedge shaped, roughly transponder antenna sized drain ports centered along the bottom of the aft 777 fuselage are for - the forward fuselage has the standard small, round drains that I remember from other types such as the 737, but the aft ones look different. Are they standard bilge drains or do they have a special function? I looked in the AMM, didn't find anything useful there unfortunately.
