When is it recommended to follow a large aircraft closely on approach?

Following a large aircraft closely on approach is discouraged due to the potential for encountering wake turbulence, which can be hazardous for smaller aircraft. Wake turbulence is created by the lift generated by large aircraft and can persist for some time, especially during and shortly after takeoff and landing. Ensuring a safe distance helps to mitigate the risks associated with this phenomenon, regardless of weather conditions such as sun or nighttime, or visibility levels.

In essence, maintaining a safe distance is a fundamental safety measure in aviation, emphasizing the importance of caution when following larger aircraft during any phase of flight. This practice is in place to protect all flying aircraft from turbulence effects that could lead to loss of control or mishaps.
