Pilot error is an erroneous term in my view(relating to the technical task of actually flying the aircraft).
More accurate would be monitoring error. The guy flying can and will make errors in many forms. selection error, decision making error etc, but it's up to the guy sitting next to him to say no!
We all know the rules and procedures but when loaded heavily or overloaded we need the monitoring over site. The probl m gets compounded when you as PF or the situation overloads both crew. My view now after an ahem.. Issue is if either one of us is pedelling like Chris froome on the Tour de France, then take up the hold at a known point above MSA and sort it before proceeding. Break the chain and the cycle.
In flight break up due mx issue bomb or shoot down is systemic failure not pilot.
