why didn`tthe pnf took controll?me think it maybe a human factor issue.
the cpt had just giveb controll to the younger pilot.bit when all happened
the pnf assumed what was wrong,but wasn`t 100% sure.
so maybe he thougt,when the cpt returned taht he (the pnf) had just took the first opportunity to take controll because he was angry at the cpt decision.
Hmm…
The name of this tread is the “final crew conversation” and it would indeed be very interesting to "listen" to how the “climat” was in the cockpit before captain left for his rest and what was said during the briefing before he left. Was there a silent competition going on? Is every crew team working in harmony, at all the time?
A car with dual drivers, dual minds, is not very uncommon. Just ask your ex-wife.
PNF thinking –Just wait until captain gets back and sees what’s going on…..
PF thinking – Me, and only me, have to sort this out…
I´m not a pilot, I just know how humans may react and handle, when under pressure.
