Vertical separation between fixed-wing and rotorcraft during operations is which value?

• A. 500 ft
• B. 1000 ft
• C. 1500 ft
• D. 200 ft

Answer: (B)

Vertical separation is the vertical distance kept between aircraft to prevent collisions. When fixed-wing and rotorcraft operate in the same airspace, a 1000-foot vertical separation is used. This buffer accounts for differences in performance and maneuverability, including rotor downwash and the potential for abrupt vertical movements by rotorcraft, ensuring there’s enough room for safe clearance during climbs, descents, and turns. The other options are either too small to provide a safe margin or larger than necessary for typical mixed-aircraft operations.
