美国联邦航空局(FAA)定于今年7月与3家制造风切变探测雷达的公司——联信、柯林斯和韦斯汀豪斯公司会面,以克服风切变探测雷达获得适航证的最后障碍。认证中有待解决的一个 技术问题是雷达对“很干”微下冲气流的探测,某些工业人士说FAA的要求太苛刻,因为现在还缺乏证明“很干”微下冲气流确实存在的科学证据。另一方面的问 The Federal Aviation Administration (FAA) is scheduled to meet with three companies that manufacture windshear detection radar in July this year, namely, Credit Suisse, Collins and Westinghouse to overcome the airworthiness certification of windshear detection radar The last obstacle. One of the technical issues to be addressed in the certification is the radar’s detection of “very dry” micro-impingement airflow, which some industrialists say is too demanding on the FAA because there is a lack of science that is proof of the “very dry” micro-downflow evidence.
