A little harsh there, blablabla. Bad day?
Our friend here is asking a question. In our operating culture, we are told there is no such thing as a stupid question, only the question unasked. Better to ask a dumb question than make a dumb mistake. I thought you UK fellows had compulsory multi-crew training courses, is that not discussed?
Our friend also specified go-around in VMC or when cleared for circling approach. If the wx and viz was hovering around the ILS minima or minima for the runway aligned approach, I would agree with you. But he asks about the VMC and/or circling cases.
If I am required to go-around due to a runway incursion in VMC the missed approach instructions are dead simple. Commence climb, maintain runway track and await instructions from ATC. Instructions which inevitably are prefaced by "can join the circuit from there?"
Why would I want to be blasting away toward 10,000' at TOGA power and a deck angle of 20deg ANU on a sunny day?
Circling approach. A clearance to make a circling approach over here is a clearance to make the IAL and circle as required to position for landing. Everything bar the landing clearance. There is no-one else in the vicinity, any inbounds are holding the other side of the initial fix. I've made the approach, I own the circuit. If I have a runway incursion, or come around base turn to find that I am too high on the PAPI and cannot make stabilised approach criteria, but everything else is fine, what is the point of blasting back into the gloop to burn more fuel and give ATC a headache?
You say the TWR and the fellow on short final behind you would have no idea. In the event of an IAL with circling, there is no fellow on short final behind me, and I am the only aeroplane flying in TWR airspace. TWR will cope just fine. APCH will not be too pleased to see me if I am back in his airspace after mucking up an approach in ceiling 1000' viz>4000m.
In VMC, dunnunda TWR controllers would have had experience of handling up to 10 training aircraft in the circuit at places like YPJT, YPPF, YSBK. A doddle. "Copied going around, make left circuit, maintain downwind until advised."
Visual maneouvring is still very much part of life in Dunnunda. Our outfit has SOP for these, it is part of the simulator and line checking programme.
