Neither of us had ever flown a route requiring it and have seen it only one time in the sim.

When we swapped seats with the deadhead crew (who have flown this route before) taking us back to CLT I asked if and how they plot depressurization routes. Got the deer in the headlights look. Thus my decision to take this to a wider audience.

Not a forum protocol expert. When I get a response to my questions from the training department, report back her?
