You ALWAYS go around on the call, and he learns from the fact that you LATER tell him it was unnecessary to call a go-around in those conditions stated.
(a) You have NO way of knowing at the time whether he has called a go-around for the weather conditions or something else - he called go-around (you say), and did not/would not typically have time to explain why
So you have a inexperienced thoroughly twitchy first officer who directs the captain to go-around. It is the captain who decides whether or not he is going to conduct a go-around - not the first officer. Same thing with a rejected take off. The first officer can scream "abort" for all he is worth - but the decision to abort is the captain's.
But to say that the captain must ALWAYS (the original writer's "shouting" - not mine) go around simply because of the personal opinion of the RH seat, is poor airmanship indeed.
