C919大型客机
C919是我国第一款按照最新国际适航标准研制的大型客机,与波音737和空客A320属于同一级别。

民航客机根据执飞航线的不同,主要分为支线飞机和干线飞机:
支线飞机主要是用于短途运输,座位数在50到110座左右,而干线飞机,也就是我们所说的“大飞机”,一般都具备洲际运载能力,它们的载客量更大,速度更快,航程更远。
大飞机主要在万米左右的平流层飞行,气流较为平稳,颠簸感也就相对弱了一些,保险公司,也通常以115座作为大型客机的分割点。

C代表CHINA,第一个“9”寓意天长地久,而“19”代表最大载客量是190座。
C919客机总长38.90米,高11.95米,翼展35.80米,巡航速度0.785马赫,最大飞行高度12,100米。标准航程4075公里,最大航程能都达到5555公里,相当于北京直飞新加坡的距离。
