If UAL433 executes a missed approach, when may N310MN start its takeoff roll?

• A. Immediately after UAL433 crosses the threshold
• B. 1 minute after UAL433 passes
• C. 2 minutes after UAL433 crosses the threshold
• D. 3 minutes after UAL433's takeoff

Answer: (C)

The correct answer is that N310MN may start its takeoff roll 2 minutes after UAL433 crosses the threshold. This timing is critical for ensuring proper separation between aircraft, especially when one is executing a missed approach.

When UAL433 executes a missed approach, it is still in the vicinity of the airport and may still be climbing to an altitude that keeps it in the airspace above N310MN. The 2-minute rule helps to establish a safe buffer, allowing enough time for UAL433 to clear the airspace and reduce the risk of an encounter between the two aircraft if N310MN begins its takeoff roll too soon.

Other options suggest either an immediate takeoff or shorter intervals. These would not provide a safe separation between the two aircraft, potentially compromising safety regulations and operational protocols established by air traffic control. Such protocols are in place to ensure that both aircraft can operate safely without putting either in danger of a conflict during critical phases of flight.
