I was recently shocked to find that a 12 year old neighbor, whose mother is a financial analyst and father is a lawyer, is unsure of the time when looking at a non-digital clock!
..... that's why they shouldn't be allowed to breed ...
My definition of 'pilot error':-
(a) If the PF breaks the aircraft.
(b) If the PF attempts to fly through cumulo-granite, or a TS.
(c) If the PF stalls on approach, too low to recover.
However, if the PF (or the 'system') stalls the aircraft at altitude and can't recover because the controls won't respond or the instruments don't indicate a stall or the PF's training is lacking; then IMHO that is NOT pilot error.
