I rack up my PIC faster than the chump who started this thread...
Every time my CA goes to the caboose to snap a bit off, i simply ignore the phone call when he wants to come back in. I make him pace the galley until we're halfway down final, then I finally let him back into the cockpit (I couldn't land with him not in the cockpit, that might get me in trouble). This way I get to put at least 20 hours of PIC in my logbook per month.
I find this to be an effective way of racking up PIC quick-time... Any of you dummies who's in the right seat and not employing this tactic is an idiot and you're wasting valuable opportunities to get to SWA within a few short months.
