How does LLWAS work? / LLWAS工作原理
LLWAS uses additional wind vanes installed
around the airport to detect wind shear
based on the ground level wind. / LLWAS利
用安裝在機場周圍的風(fēng)向標(biāo)檢測近地風(fēng)切變。
The system uses a fluid
modelling algorithm to
deduce the presence of
wind shear or
microbursts based on the
measured surface wind. /
系統(tǒng)基于測量的地表風(fēng)使
用流體建模算法推算出地

The result is presented
on a graphics console in
the control tower and
used to improve the
safety of all landings and
take-offs at the airfield. /
