Coordination Level (CL) defines the separation between which types of aircraft?

• A. Separation between civil and military traffic.
• B. Separation between airspace sectors in a layered design.
• C. Separation between fixed-wing and rotary-wing aircraft.
• D. Separation between airfield operations and in-flight operations.

Answer: (C)

Coordination Level is all about safety when two different aircraft types operate in the same airspace. The key is that fixed-wing aircraft and rotorcraft behave very differently: fixed-wing fly fast, require larger turns, and usually operate at higher altitudes, while rotorcraft can hover, descend, and maneuver at low speeds and in tight spaces. By defining how much separation is needed between these two types, airspace planners and controllers can prevent conflicts and maintain safe operations during mixed-fleet missions. This concept isn’t about civil versus military traffic, nor about how airspace is divided into sectors or layers, nor about airfield versus in-flight operations.
