w_g_u.... Ah I understand now. At Heathrow we have a similar potential conflict between south-east bound departures off 27R and a missed approach off 27L. As I'm sure you know the runways are operated independently with arrivals on 27L often 2.5 miles apart, so there is always the potential for a go-around.
The missed approach procedure on 27L is to climb ahead to 2000ft initially but after passing 1000ft aal or zero ILS DME, turn left onto a SE track and eventually climb to 3000ft.
The idea is that if all else fails, a SE bound departure off 27R will almost always be at or above 3000ft when the potential conflict occurs and the aircraft going round will be not above 2000ft. This is not a guaranteed separation and normally the controllers will intervene to ensure separation between the aircraft. Nevertheless it means that traffic at the airport is kept moving.
Obviously I don't know the situation at LSZH with regard to separations but perhaps thinking along these lines might be beneficial.
