will require the non-handling pilot to break out the laptop and recompute the landing distance, redo the ref, rebuild a centerline on the FMS, set up the missed approach while simultaneously talking to ATC, and participating in config changes, etc, etc, etc....
Yes...... so you tell ATC you need 5 mins, hold somewhere safe and re-brief your imminent challenging wx affected circle to land. You don't just plough on with the PNF working like a one armed paper hangar!!
It's called non-technical skills. Workload management, cooperation, situational awareness. These are essential elements. A lot of discussion so far has talked of technical aspects (did this aircraft have GPS?) and possible mapshift. The only reason I can see that they ended up 7 miles north was a breakdown in the non- technical side of things which would of course be exacerbated by having a brand new FO in the other seat.
