To mitigate the risks associated with wake turbulence, the FAA has invested in extensive research over the years. Studies dating back to the early 1960s illustrate the evolution of understanding surrounding wingtip vortices. For instance, tests using smoke grenades allowed researchers to visualize and measure the characteristics of these vortices under various conditions.
During the 1970s, further research was conducted on new heavy jets, including the Boeing 747. Observations confirmed that larger aircraft created wake turbulence with a greater field of influence compared to older aircraft.
Key Findings on Vortex Behavior
Through a series of flight tests, crucial findings regarding the behavior of wake turbulence emerged:
