Nowhere in there does it say 'immediate'.
expeditious, but unrushed, manner.
Quite.
abandon [your] approach to landing
You are abandoning your approach, once a go-around has been called I have no intention of landing. I am content to remain in the safe approach path until which point I carry out my manoeuvre.
A pilot on an IFR flight plan making an instrument approach should execute the published missed approach procedure or proceed as instructed by ATC; e.g., “Go around” (additional instructions if required).
Again quite correct but nowhere does it say execute immediately. Take a few seconds, explain what you are about to do and execute it. My bold but of often the published missed approach begins at decision height or the runway threshold.
What's the problem with that?
