Can overflights enter JAN APCH airspace during non-radar operations?

During non-radar operations, overflights are not allowed to enter the airspace of an airport's approach control (JAN APCH) without explicitly following established protocols. This restriction exists primarily for safety and coordination purposes. When it comes to managing air traffic, particularly in non-radar situations where real-time tracking is not available, it is crucial to maintain separation between different aircraft types and operations.

Your understanding that overflights cannot enter JAN APCH airspace aligns with the fundamental principles of air traffic management where communication, coordination, and the regulation of traffic flows are critical. This maintains safety and helps the approach controllers effectively manage incoming and outgoing aircraft.

In contrast, the other options suggest scenarios where overflights could enter the airspace, which could potentially disrupt the careful balancing needed for safe operations, especially when radar capabilities are not in place to monitor their movements.
