其實各民航業者也要負點責任,各公司都不想要全新的797,只想要駕照可以續用的737,所以波音只好在737上硬裝大引擎。
這顆引擎實在太大,連水平安裝都不可能,必須稍微朝上安裝,而這朝上的角度在催油門時,就會把機體角度過度上抬,抬到會失速墜落的角度。
於是只好導入自動壓角度的尾翼設計(也是為了駕照續用),但角度感應器又省錢只裝兩顆,任何一顆稍微故障都會誤判角度,然後就進入人機搏鬥忽上忽下的狀態。
衣航空難的影片,看得出最後是角度拉太高失速墜毀,可能那時駕駛才剛把自動穩定系統關掉,但控制桿依然維持在高角度,油門也大開導致失速。
油門大開來避免失速,可說是飛機駕駛都有的潛意識動作,但這習慣動作在737MAX反而會失速,是非常違反直覺的設計。

Mentour Pilot 說高角度油門直接大開下突然又一個抬頭的動力反而會造成第二次失速,尤其是那個MAX 8。。。
