Is it reasonable, in your opinion, for the Commander of the aircraft, Cjet, who can see a potential conflict developing, Ajet rotating beneath his aircraft and climbing very steeply, to advise ATC of the intention to fly a non standard go around in advance? Do you consider this as sensible as you, in ATC, may have traffic elsewhere in the pattern and need to have an idea, in advance of what the aircraft will do?
Completely reasonable, and if I had a different plan, because of that traffic in the pattern that you mentioned, then this is when I would probably let you in on it!
