As part of our recurrency sims we practice the incapacitation sinario (even if I cant spell it). It is our company SOP and as such it is what I am trained to do, and will do. Should you not follow the SOP and something does go wrong your ass is realy in a sling. It probably is anyway but thats another story....
We do not practice the FO landing in low viz, but I know I can fly a single pilot go around and safely divert to a Cat I field.
Do no other airlines legislate in this case?
