I have a question regarding a swingover (I'm flying in an JAA/EASA country, so that's the term we use; the FAA guys probably know it as sidestep). Assuming I've been cleared for an instrument approach at an airport with a parallel RWY system and I'm on final and the controller asks me if I can accept a swingover to the other runway. I confirm that and he clears me to swingover and land.
Now let's say s/he didn't specify any missed approach to be followed, which one shall I fly? Of course, in the real world, I'd ask, but is it laid down anywhere which one I'd have to follow? Both missed approaches have their pros and cons I suppose. Following the missed approach for the instrument approach runway is easy for workload, nothing new to be briefed on final, heads can remain up, but I might interfere with traffic from that runway. On the other hand, following the missed approach for the landing runway doesn't have the traffic issue, but it forces (unless VERY familiar with the airport) one pilot to check for the new missed approach in a low altitude environment, which is not safe either.
So, which one is it (if it's in the regulations)? As mentioned before, if in doubt I'd always ask, but just wondering in case a check captain puts me in that situation and expects me to know and act accordingly.
Thanks for your answer, I'll appreciate it.
