Wake turbulence primarily impacts which aspect of ATC separation planning?

• A. Sequencing and spacing for arrivals and departures
• B. Ground operations at the airport
• C. Angle of bank in turns
• D. Communication protocols

Answer: (A)

Wake turbulence management focuses on safe distances between aircraft as they move through the most vulnerable phases of flight, especially near the runway. Vortices shed by a heavy aircraft can linger and move into the path of following airplanes, potentially causing loss of control or instability if those aircraft are too close. Because of this, the planning of ATC separation is driven primarily by sequencing and spacing for arrivals and departures. Controllers adjust the order and the spacing between aircraft to ensure a heavy aircraft’s wake has dissipated or moved clear before the next aircraft, particularly when the following airplane is lighter or operating in a constrained airspace or on final approach. Ground operations, bank angle decisions, and communications protocols don’t govern wake-related safety distances. Ground ops deal with taxiways and runway occupancy, bank angle is a pilot maneuver during turns, and while clear communications are essential, they do not determine wake-induced spacing requirements.
