Wake Encounter Analysis for a Closely Spaced Parallel Runway Paired Approach Simulation

A Monte Carlo simulation of simultaneous approach es performed by two transport category aircraft from the final approach fix to a pair of closely spaced parallel r unways was conducted to explore the aft boundary of the safe zone in which separation assurance and wake avoidance are provided. The simulation included variations in runway centerline separation, initial longitudinal spacing of the aircraft, crosswind spe ed, and aircraft speed during the approach . The data from the simulation show ed that the majority of the wake encounters occurred near or over the runway and the aft boundaries of the safe zone s w ere identified for all simulation conditions.
