I Fly ... from the few obs flights I've done, it seems that the airline routine is to brief, in part, by comparing chart date, along the lines of ... "this will be the ILS RWY 04 approach at Brisbane and my chart date is...". PNF responds by confirming the same date on his/her chart.
The theory, I suspect, is that its highly unlikely that both of them will have the same out-of-date chart. Perhaps there's some QF or PX crews out there who can clarify the situation for us all? If this is the case, it probably won't help you too much, I Fly, as airline crews will undoubtedly all have Jepp charts and, therefore, not have to cross-check with the same AsA chart.
