When landing behind a large aircraft, which procedure should be followed for vortex avoidance?

When landing behind a large aircraft, it is essential to stay above its final approach flight path all the way to touchdown to avoid the risk of encountering wake turbulence. Large aircraft generate powerful vortices, especially during takeoff and landing phases. These vortices can linger in the air for a significant distance and can be particularly dangerous for smaller aircraft, as they may cause unexpected and severe changes in airflow.

By remaining above the final approach path of the larger aircraft, pilots can effectively mitigate the risk of experiencing wake turbulence. This strategy allows for better control over the aircraft and a safer landing environment. The other procedures, such as descending below the final flight path or landing directly behind the large aircraft, put the pilot at much higher risk of encountering these dangerous vortices, which can lead to loss of control. Thus, staying above the final approach path is the most effective method for ensuring a safe landing when following a larger aircraft.
