EPIRB, do you understand the difference between strategic and tactical? Do you understand the idea behind COBT and that we as line controllers have neither access to nor influence on it.
We don't decide the acceptance rate, we don't decide all the rules, we just work with the traffic disposition we're given. Sure you might have been delayed by an hour but how does that position you with reference to the actual sequence? It doesn't does it? We have to tweak things to make it all fit.
We're as mystified as you as to where all the delays come from on some days.
If you've got a bitch about the way it all works get your bean counters to talk to our bean counters to talk and the airport bean counters. They're the ones controlling it all.
