Ive read some total garbage on PPRuNe over the years. This ranks highly.
If someone in the front says go around, you do it. Discussion can occur after. The number of accidents where the FO has called for the go around and the idiot captain thought he knew better, and didn't, are numerous.
I'm yet to find an incident where an FO called for a Go Around that wasn't required and people died. Have you?
No it is the PIC decision. That is the way the law and aviation has always worked. And I am not saying you ignore the FO, or don't err on the side of caution, however to start officially white anting the authority of the PIC by just having arbitrary rules will just create a laundry list of unintended consequences.
There are numerous reasons why not going around may be the best call. EK 521 is probably the poster child of why arbitrary decision making by people not in the flight deck is not always leads to the best outcome
Similarly if you have a steep experience gradient in the cockpit are you just going to go around because of a cadet pilot in the RHS thinks its a good idea? If that's the way aviation is going noone will be going anywhere unless the wind is down the runway and its CAVOK.
Being a PIC is about knowing your limits and the aircrafts and not being pushed outside of those limits by anyone but by also knowing what you and your aircraft are capable of. By pandering to the lowest common denominator we are just going to grind the whole industry to a halt.
