Confliction on Go Around
May I ask your opinions on this situation folks?
With Cjet at 6nms ATC clears Ajet to line up after the landing Bjet.
Cjet starts a reduction to min approach at this point.
Bjet is slow to clear the runway and at 3nms Cjet is advised to expect late landing clearance.
When Bjet clears the runway Ajet is given take off clearance, but doesn't roll.
Cjet advises ATC, that in the event of a go around, the aircraft will turn right to avoid conflict with the departing Ajet as the normal go around is straight ahead 3000ft and the SID is straight ahead to Nnms turn left climbing FL XX.
At 1.5nms the controller, having issued a "Ajet roll now" instruction realises it isn't going to work and instructs Cjet to "Go around turn right onto north and climb 3000ft"
Cjet complies and just before the go around is initiated Ajet begins the take off roll.
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?
Or would you prefer that Cjet flew the standard go around and left you to sort out the mess?
