After UAL433 executes a missed approach over Runway 28R, when may N310MN, a C310, start its takeoff roll?

The correct answer indicates that N310MN, the C310, may start its takeoff roll two minutes after UAL433 crosses the landing threshold. This timing is crucial in air traffic control as it ensures adequate separation between aircraft following a missed approach procedure.

When an aircraft executes a missed approach, it may still be in a climb-out phase, and the airspace around it remains busy until sufficient time has passed to ensure that it has safely cleared the intended takeoff path of any departing aircraft. The two-minute interval established is a standard practice to enhance safety and to allow the missed approach aircraft to gain altitude and distance.

This consideration helps in preventing potential wake turbulence issues, as larger aircraft such as the UAL433 generate significant wake that could affect smaller aircraft taking off nearby. Therefore, waiting for a specified time after the larger aircraft's action is a critical component in maintaining safe operations at the airport.

In this case, the options that suggest immediate takeoff or less than the two-minute interval do not take into account the necessary spacing and safety protocols that are designed to prevent accidents and ensure a smooth flow of air traffic.
