A wingtip vortex is a circular pattern of rotating air that forms at the tips of an aircraft's wings as it generates lift. This phenomenon occurs because the higher-pressure air beneath the wing flows around the wingtip to the lower-pressure area above the wing, creating a spiral of air. These vortices can extend several hundred feet behind the aircraft and are particularly strong during takeoff and landing. Wingtip vortices are important for pilots to understand, as they can pose a hazard to smaller aircraft flying behind larger ones. The strength of these vortices is influenced by factors such as the aircraft's weight and speed. Awareness of aircraft safety and air traffic control procedures helps mitigate risks associated with wingtip vortices.
