What type of aircraft generates the strongest wake turbulence?

The strongest wake turbulence is generated by large aircraft due to their significant weight, size, and the resulting impact it has on the airflow around them during flight. When a large aircraft takes off or lands, it creates powerful vortices that trail off its wings as a byproduct of lift generation. These vortices are particularly concentrated and long-lasting compared to those produced by smaller or medium-sized aircraft because of the larger wingspan and the greater mass of the aircraft.

Additionally, large aircraft are often piloted at lower altitudes during takeoff and landing, where turbulence effects are amplified, posing collision risks for following aircraft. Consequently, the considerable momentum and disturbed air patterns produced by larger aircraft lead to more severe wake turbulence, making awareness and proper spacing crucial for maintaining safety in air traffic operations.
