AIRCRAFT WAKE VORTEX SCENARIOS SIMULATION FORTAKE-OFF AND DEPARTURE

摘要

The WakeScene-D software package (Wake Vortex Scenarios Simulation Package for Departure) has been developed for comprehensive airspace simulations of take-off and departure. WakeScene-D consists of modules that model traffic mix, aircraft trajectories, meteorological conditions, wake vortex evolution, and potential hazard area. The software package estimates the probability to encounter wake vortices in different traffic and crosswind scenarios using Monte Carlo simulation in a domain ranging from the runway to an altitude of 3000 ft above ground. The operating sequence of WakeScene-D, the employed sub-models and data bases, the simulation environment and evaluation tools together with the so far accomplished validation work are introduced. The current departure situation with a two-minute aircraft separation is compared to (i) a scenario with reduced separations of one minute, (ii) the mitigation effects of crosswind and (iii) the situation prevailing during approach and landing.
