Out of interest do our ATCO friends know what it means to us as pilots?
As far as I'm aware, it means you have enough fuel to make an approach and then divert to your alternate to land there. Whether or not you have enough to hold there I don't know. We did have something about on our briefing system a while back, but the exact details escape me now.
You need to declare a PAN before you get any preferential handling from ATC though, but I guess you already know that
