Mitigating Wake Turbulence Risk During Final Approach via Plate Lines

To mitigate the risk of wake vortex encounters during final approach, so-called plate lines have been developed. Wake vortices generated by landing aircraft induce secondary at plates’ surfaces that approach primary and trigger premature decay. Each line consists several upright plates being installed underneath slope. While extends perpendicular to flight direction, its individual are oriented in parallel runway centerline. obtain approval authorities for installation 16 Vienna International Airport, design had comply with airport requirements like obstacle clearance, stability, frangibility. During a six-month campaign, behavior about 9500 landings without was measured simultaneously three lidars complemented comprehensive suite meteorological instrumentation. The analysis over 1000 evolutions indicates reduce lifetimes safety corridor along 22–37% depending on type. This corresponds reduction circulation 50% most relevant Civil Aviation Organization separation (Medium behind Heavy).
