SWA601, a B737, executes a missed approach over Runway 28R. N1388V, a C421, is waiting to depart Runway 16. N1388V may depart ___.

• A. after runway separation requirements are met
• B. immediately
• C. after 5 minutes
• D. after contacting tower

Answer: (A)

The main idea is that separation between traffic on intersecting runways must be established before a second aircraft can depart. When one aircraft is performing a missed approach on a runway, its path and climb area near the runway can conflict with departures from a crossing runway. ATC must ensure the required runway separation is met to prevent any crossing-conflict during the missed approach and the other aircraft’s departure.

So N1388V may depart only after the controller confirms that the necessary separation (distance or time, as defined by standards and current conditions) is in place. Waiting a fixed time or just contacting the tower doesn’t guarantee that a safe clearance exists; the departure is permitted only when separation criteria are satisfied.
