The surface structure of the earth's surface to promote the decay of wake turbulence of the short final of the entry area to the runway

摘要

Provided in the short final approach area of ​​to the (101) runway that has a (104) runway axis and (102) runway beginning, the present invention relates to a surface structure of the earth's surface (106). In order to facilitate the attenuation of the wake turbulence aircraft come as landing approach occurs, according to the present invention, comprises standing a plurality of individually independent from (105), surface structure, they stand is in the range of 1~5m especially also 0.25~10m, to (h), 1~600m, 1~400m, 1~200m, 1 interval they stand of death if (105) (a) height ~100m, 1~50m, 1~25m, 1~15m, or 1~10m,, it is in the range of 2~8m especially.
