Ajax thanks for answering so many questions. I realize that we can't save time and fuel and like the other guy said its not about saving fuel as much as knowing how much farther I have to fly to get to the runway so I have a better idea of when to pull the plug and head somewhere else.

I understand the zig zag works best to get the tight spacing which is good. The downside for us is the zig zag takes away some info that could help us from being the next Avianca. My company says we are supposed to declare min fuel when it looks like we will burn into our reserve fuel. If I don't know how far I have to fly to get to the runway its a little harder for me to come up with a number to use to declare min fuel.
