I'm working like you too, Mark. The initial fix should be as accurate as it could be while the rest is done with the DME updates. We should operate as accurate as we can to allow the system to do it the same way.
If the accuracy at the end of the flight really reflects this whole investment? I don't know, but I hope so.  :)
You won't land at the wrong airport when picking the 4 instead of the 5 there though.  ;D

By the way, did some of you ever land at the wrong one? I did once, but this wasn't a Civa flight. I laughed about this "incident" for quite some time when thinking about a real pilot acting like this.
