What is Coordination Altitude?

• A. An airspace coordinating measure that uses Alt to separate users as they transition between different airspace controllers
• B. The altitude used for naval gunfire approval
• C. A vertical limit used for sea-lane operations
• D. A schedule for airspace deconfliction

Answer: (A)

Coordination altitude is an airspace management tool that uses a defined altitude to keep airspace users separated as they move from one controller to another. When aircraft cross from one airspace sector or control authority to another, controllers need a clear handoff point so they don’t accidentally issue conflicting instructions. By agreeing on a coordination altitude, both sides know the aircraft will be at or near that level during the transition, allowing them to maintain separation and reduce risk of conflict.

This concept is about how airspace is deconflicted through coordinated handoffs between different controllers, not about naval gunfire approval, sea-lane vertical limits, or a schedule for deconfliction.
