they really shouldn’t be. They are a pre-briefed contingency to any instrument Approach or visual approach, or at least should be.
A go around isn’t inherently dangerous or an overload of work. It’s only that way when a crew makes it that way by failing to pre-brief one, and by extension, not being in the mindset to expect one and be ready for same.
Have had two real missed for Wx mins, and two or three actual go-arounds in VMC to a closed traffic pattern, and all of them were relative non-events in a transport category aircraft, since they’re required to be pre-briefed as part of the Approach brief, and thus expected, even if they don’t happen. They’re also practiced a lot.
