During non-radar operations, what airspace does ZAE assume over JAN?

The assumption of airspace by ZAE over JAN during non-radar operations primarily concerns ensuring safe separation and effective management of air traffic in the terminal area. The correct choice indicates that ZAE has control over air traffic at and above 6,000 feet within this area. This altitude allows for adequate vertical separation from potential traffic below this level, including departures and arrivals, which are typically operating at lower altitudes.

Establishing operational control at and above 6,000 feet is important for maintaining safety margins, especially in non-radar environments where aircraft position reporting may be less frequent and dependent on altitude and airspace management protocols. By controlling operations starting at this altitude, ZAE can focus on managing the more congested lower levels separately, where the majority of maneuvering and critical phases of flight—such as takeoffs and landings—occur.

This altitude demarcation is essential for maintaining the structure and order of air traffic in an area that can see varying aircraft movements, ensuring that both commercial and general aviation vehicles can operate safely and efficiently.
