As far as I'm aware there are two different ways to fly sparge. Both start with adding enough sparge (or mashout) water to get about 1-2" of liquid over the grainbed. At that point you start running wort out and adding sparge back in to keep the level constant. Where the difference occurs is the following:
1. You specifically measure out your sparge volume so that when the tun runs completely dry, you have your preboil volume exactly. I'd call this a type of hybrid fly/batch sparge.
2. You continue adding sparge water all the way through and just stop collecting when you hit your desired preboil volume (or you hit 2-3 brix on the runoff whichever comes first). I THINK this is the more traditional, "true" way to fly sparge.
Anyway... hit up the poll, let's see what's what.
