Which aspect does not play a role in controlled airspace management?

In the context of controlled airspace management, extended landing procedures are not a primary concern. Controlled airspace primarily focuses on ensuring safe and efficient operations of aircraft through various means, such as separation of aircraft movements, effective communication with pilots, and monitoring of traffic congestion.

Separation of aircraft movements is essential as it ensures that aircraft maintain a safe distance from one another to prevent collisions. Communication with pilots involves relaying important information and instructions, thus helping pilots navigate safely and efficiently within controlled airspace. Traffic congestion monitoring is also crucial as it allows air traffic control to manage the flow of aircraft, preventing bottlenecks and ensuring that air traffic remains orderly.

While extended landing procedures may be a part of an airport's operational guidelines, they do not directly relate to the broader management of controlled airspace, which focuses on the factors mentioned above to maintain safety and efficiency in the airspace system.
