Optimized and quality assured aircraft noise calculation on the basis of radar tracks

摘要

Modern aircraft noise prediction methods afford a tremendous amount of work to convert flown flight patterns into model data which can be used for calculations. Especially for existing situations this procedure could be much quicker and errors could be avoided, if prediction methods would allow the direct use of radar tracks. During this study the efficient use of radar tracks (STANLY and FANOMOS) was evaluated and compared against measurement results. There were several difficulties to overcome, such as automatic conversion of coordinates, automatic conversion of UTC time to local time (including DST), assignment of tracks to the correct runway, assignment of emission data, the use of spline and filter functions to adopt the tracks and reduce at the same time the amount of track points, selection of unusable tracks (to short, pattern flights, no emission data).
