【精選】波音又出包急墜險落海？美石墨戰拜登急求非洲？ 新聞大白話 

出現了那麼多的事故，還不足以證明波音飛機的安全性有大問題嗎？ 還不立即禁飛所有的波音飛機！

人要蠢 你給工具 它照樣做反 🙄腦不行Y

👍👍👍

不会不要评论，如果成分不合，可是成分到对方都有检查，还是对方的问题？每家公司都是，一样的成品到买家一定检货是对的成分。

波音機如安裝了有中國制造的產品, 那為了國家安全, 美國FAA是不是應該立即停飛全美國波音機甚至全世界的波音機嗎？你美國玩的起嗎？😂

亮亮说得对，停飞好了

中文字幕 ？

跟英美日等國脫鈎吧！

宝钛集团 很有名的

一定是印度软体。

為什麼世界不阻止波音飛行？就像日本的汽車使用劣質材料一樣¡

若要搭剝陰剋雞？請自求多福、並多買更多人身意外保險吧？

今天的中国在他们心里是魔术师是孫悟空。

川普說的好像烏克蘭帶走美國600億美金不用還的樣子...不是說要還的嗎? 那樣再借600億美金有問題嗎?　XD

我有一批牛肉很便宜。😂😂😂

The nose of Boeing 737 Max 8 tends to pitch up during a specific extreme manoeuvring situation after the classic Boeing 737 was modified to compete with Airbus 320 by changing the two engines and relocating their positions to avoid the bigger engines being too close to the ground level. After the modification, Boeing announced that the pilots of the Classic Boeing 737 are NOT required to be trained about the effects of the modification and the incorporation of the MCAS. The pilots can fly the Boeing 737 Max 8 like flying the Classic Boeing 737 planes.

Unique to Boeing 737 Max 8, The Maneuvering Characteristics Augmentation System 機動特性增强系統 (MCAS) is a computer software incorporated to control the nose tendency to pitch up during a specific extreme manoeuvring situation. The MCAS will push the nose down after receiving the sensor data from the Angle-of-Attack Sensor 攻角感應器. It keeps pushing the nose down if the sensor data were inaccurate until the plane touches the ground. This was what had happened in the plane crashes in Indonesia and Ethiopia in 2018. The MCAS Computer Software was outsourced by Boeing to an USA based, Indians run company named the Collins Aerospace Company. After the two planes crashes in Indonesia and Ethiopia respectively, the exact reason(s) why the planes were flying like a headless fly has not been stablished. It is also unclear if the software had been modified to date.
