Wake turbulence is the disturbance in the air created by aircraft as they generate lift, forming pairs of counter-rotating vortices behind the aircraft in forward flight. These vortices interact with the surrounding atmosphere and gradually decay over time. Turbulence from larger aircraft can pose hazards to trailing aircraft, potentially causing significant upsets that may result in personal injuries or aircraft damage.

Discipline leadership supports the analysis, research, and guidance related to wake turbulence and its effects on aircraft operations. Areas of responsibility include harmonization of international standards and  collaboration with FAA leadership, industry, other government agencies, academia, and air traffic control organizations. This collaboration aims to inform safety policies, training, and operational procedures that mitigate wake turbulence hazards and enhance safety in the national airspace system.
