What does Coordinating Altitude (CA) allow for in airspace management?

Coordinating Altitude (CA) is essential for effective airspace management as it facilitates the separation of users via altitude. This means that different aircraft operating at designated altitudes can coexist in the same airspace without conflict, enhancing safety and efficiency in operations. By establishing a CA, airspace planners can ensure that various types of air traffic—such as commercial, military, and general aviation—can share airspace without interference, which is critical for maintaining orderly flight operations.

This altitude allocation becomes particularly important in environments with multiple users, enabling seamless coordination and communication between air traffic control and airborne operators. The implementation of a CA is a crucial aspect of airspace structure that optimizes the use of vertical space, which is limited, especially in busy air corridors.
