The standard missed approach is designed to keep the go-around away from departing traffic (for example with comms failure),...
Is it? Consider a missed approach on 9L and a BUZAD 3J SID on 9R. The missed off 9L is straight ahead to 1500 ft then left onto 040. The BUZAD 3J off 9R is left onto 053 at LON 2d (which is just about at the upwind end of the runway), no restriction on climb to 6000 ft.
It looks to me as if the aircraft are not separated without proactive controller input. Am I missing something?
