国产大飞机办个证,为啥需要总理亲自过问?(图)

2017-06-02 07:33:48   中国青年网

那么,美国和欧盟的适航证好不好拿呢?又严苛在哪里呢?

严苛

揭裕文告诉侠客岛,适航的理念,是要求申请的航空器及其部件,即使在苛刻条件下,也能安全飞行。美欧的适航标准,就主要严苛在安全性能上。

比如,美欧标准中有一个要求,就是“结冰飞行”,这种自然结冰天气在中国本来就很难找。中国此前自主研发的支线飞机ARJ-21,为了寻找满足实验条件的天气,在新疆寻找了两年都不得,最后还是在加拿大才实现。

其实,不光是FAA和EASA的标准严苛,中国自己的CAAC适航标准也一样严苛。

拿ARJ21来说,从2003年申请,一直到2014年才拿到适航证,十二年间经历了许多波折。光中国民航局对这款飞机审查的符合性验证报告,就有30多万页,累起来有30米高!除了前面说到的自然结冰,还有长沙的高温高湿试验、大侧风天气、最小离地速度试验、最大刹车能量等许多苛刻条件,ARJ21的整体试飞时间,就达到5000多小时。

对民航客机来说,如何强调安全都不过分。在揭裕文看来,要完全取消大众对国产大飞机的安全性疑问,就必须取得适航证,满足民航法规要求。C919只有在这套标准体系中证明自己的安全品质,才能获得全球航空市场的“登机牌”,获得人们用脚投票的信任。

“其实,中国自己的CAAC适航标准,完全已经达到了国际先进水平。CAAC认定的‘安全’是什么概念呢?飞机事故率是百万分之0.3——相当于你每周坐10个小时的飞机,就这么飞上五六千年,才会出一次事故。”揭裕文说。

他告诉侠客岛,目前,中国的CAAC已经和美国接轨,大部分都是参照美国FAA的法规和标准制定的,90%以上的内容重合、甚至有的的是直接翻译过来,基本没差别。也就是说,只要C919获得中国民航的认证,安全性就完全可以保证。

那么,为什么还要如此费劲地去拿美国和欧盟的认证、甚至要总理亲自提点这件事呢?

这是因为,在一些时候,中国的大飞机要走出去,也不光是一个技术问题,还涉及到一些政治问题。
