The ZAE/ZHU LOA specifies clearance for aircraft below which altitude?

The correct altitude specified in the ZAE/ZHU Letter of Agreement (LOA) for clearance of aircraft is 12,000 feet. This means that aircraft operating below this altitude have specific procedures and clearances outlined in the LOA to ensure safe and efficient coordination between ZAE and ZHU air traffic control facilities.

This altitude typically represents a standard practice limit for tactical separation and operational control between different air traffic control sectors, allowing for better management of traffic and ensuring that aircraft can operate safely without conflicting with other operations. The selection of this altitude might reflect both operational needs and regulatory requirements designed to maintain safety.

In contrast, the other altitudes listed (10,000', 14,000', and 16,000') either exceed this specific coordination level or may not offer the same structured environment for air traffic control interactions as outlined in the LOA. Thus, understanding the significance of 12,000 feet in this context helps reinforce the operational framework established by these agreements.
