Read this yesterday consequent to a renewed CAA instruction:
At the initiation of any go around manoeuvre, especially one near to or even in contact with the runway,
workload is significantly increased so that they are likely to be functioning much nearer their
mental capacity than during the approach phase. Notwithstanding their need to communicate with aircraft making a go around to assure traffic separation, Air Traffic Control, need to recognise that this is a time to keep communication to a minimum commensurate with safety. The only additional communication which will be helpful to pilots beyond instructions essential for separation are those which simplify the go around being flown - for example by increasing the stop altitude or issuing a radar heading in place of a complex tracking sequence. The message is that ATC can make an
important contribution to go-around safety.
SKYbrary - Go-around Execution
Seems that ATC should not give routine, only emergency instructions at a late phase in landing. It also suggests that the capacity to decipher transmissions at that time might be diminished.
