“…Here, we exemplarily perform a simple estimation of uncertainty for the most important parameter, which is lateral vortex transport, at a vortex generator height of about 50 m, which is within the most critical height range of 100 m above ground [1,9]. For B744 and A343 aircraft, the difference of predicted and measured standard deviations of lateral aircraft position amounts to ac 6:8 m. For these aircraft types, the median RMS deviation of measured and predicted wake-vortex positions employing the D2P model has been estimated to vort 19:2 m [20].…”
