Actually, as part of the phase II selection you visit the Ops room as a matter of course. The visit lasts 20 minutes or so.
Being alert to what's going on in the ATC business is, of course, a must. Know about stuff like RVSM, and pay attention in your visit to the Ops room!
Minimum Rest: Sent you an email to your PPRuNe address, did you get it? I have been a divot and lost your other email address. Something to do with computers getting repaired and hard disks getting formatted in the process. RSVP to my normal address?
