wingtip fences

Wingtip fences are small vertical or angled surfaces mounted on the wingtips of an aircraft. They are designed to control and reduce wingtip vortices—spinning air masses created by the wing generating lift. These vortices can cause turbulence and aerodynamic drag, impacting aircraft performance and safety during takeoff, flight, and landing. By altering airflow at the wingtips, fences diminish vortex strength, improve fuel efficiency, and enhance stability. Essentially, wingtip fences help manage airflow to make flying smoother, safer, and more efficient.
