In ACM separation between fixed-wing and rotary-wing assets, which term denotes the altitude used for coordination?

• A. Coordinating Altitude
• B. Coordinated Level
• C. Separation Altitude
• D. Clearance Altitude

Answer: (A)

The coordinating altitude is the reference altitude used to coordinate and deconflict fixed-wing and rotary-wing aircraft. It provides a common vertical level for planning and communication, so both asset types can align their actions and maintain safe separation even as they operate in shared airspace. This term specifically denotes the altitude used for coordination, not the actual flight levels or clearances. The other terms describe different concepts (actual separation boundaries, issued clearances, or nonstandard labels) and don’t capture the precise role of a fixed reference for coordination between asset types.
