To the 20,000 hr guy who takes the opposite view I say I know where you're coming from but as someone else said which "wrong decision" would you prefer the F/O to make? I know I can screw up just a fast as the next guy but I hope I'm not so proud that I'd ignore a genuine call - no matter how "wrong" I might think it is. I'd much prefer to discuss it afterwards in the bar than in the enquiry!!!
Or in heaven.........................
Having flown (& doing so now) with 200hr FOs, some are very good, some are not...As a FO, I flew with some 20,000 hr CPTs, some were very good, some were not.
So, you cannot generalise. The minute you profess to be perfect is the time you should go & get another job!
Remember, to err is to be human & NONE of us is infallible.That is one of the reasons they put two pilots (or more) on the flight deck. Yes, there has to be a cross cockpit gradient, BUT the other guy should not be frightened to speak up. (Teneriffe North springs to mind.)
As few previous posters have mentioned, I would much prefer the odd spurious go-around (part of the learning curve, we all had to make)as "we" may have missed something, rather than something much worse!
