A light crosswind can significantly affect the behavior of wingtip vortices created by a large aircraft during takeoff. When a large aircraft becomes airborne, it generates vortices at the tips of its wings, which are a byproduct of the lift being produced. These vortices tend to drift downward and outward from the aircraft's flight path.

In the presence of a light crosswind, one of the vortices can be pushed laterally, remaining closer to the runway, while the other vortex may be carried away from the departure path. As a result, one of the vortices lingers over the runway for an extended period, which can create a hazardous condition for any following aircraft, especially smaller ones that are more susceptible to wake turbulence. This lingering vortex is important to recognize, as it can affect flight safety during takeoff or landing phases for subsequent aircraft.

The understanding of this phenomenon is crucial for pilots, as it emphasizes the importance of maintaining sufficient separation from larger aircraft to prevent wake turbulence encounters, which can disrupt control during critical phases of flight.
