During non-radar operations, what airspace does ZAE own over MLU APCH?

The correct answer is that ZAE owns airspace at or above 7,000 feet over MLU Approach during non-radar operations. In non-radar environments, air traffic control responsibilities include managing the airspace to ensure safety and efficient flow of air traffic. The altitude restriction of 7,000 feet and above for ZAE suggests that below this level, other airspace control measures may apply, or other entities may have jurisdiction over lower altitudes.

This separation in altitude helps prevent airspace conflicts and ensures that each controlling facility can effectively manage the aircraft operating below and above that threshold. Therefore, operating above 7,000 feet allows for structured and safe management of aircraft transitions into and out of controlled airspace around MLU while maintaining necessary clearances below that altitude where different operational rules may be in effect.
