When should a closed pattern NOT be requested?

A closed pattern should not be requested during traffic conflict on the high downwind because safety is the primary concern in aviation operations. If there is a traffic conflict, requesting a closed pattern could potentially exacerbate the situation, increasing the risk of collisions and creating additional complications for air traffic control and other aircraft in the vicinity.

In a closed pattern, the aircraft flies a rectangular route that includes repeated circuits around the runway. If another aircraft is nearby or in conflict with this route, it is essential to maintain clear communication and resolve any potential hazards before proceeding. Therefore, it is critical to avoid requesting a closed pattern when the risk of conflict is present to ensure a safe and effective operation.

Other scenarios might present challenges or considerations, but none pose the immediate safety risk that a traffic conflict does. Requests for closed patterns should prioritize the safety and efficiency of operations, which is compromised in the presence of traffic conflicts.
