但氣動結構物理限制無改變到。新聞已經有描述。

最重要部份係對翼。機身係相對次要

要留意呢個自動駕駛系統目的唔係輔助，個logic係，因為氣動結構問題，萬一失速人類可能難以挽救，所以必 ...

果個唔係自動駕駛系統，果個真係輔助系統，原理係當Auto-pliot disconnected先會介入。

737-100/200->737-300: 換大量航電設備 + engine
737-300->737NG: 換大量航電設備 + 機翼設計
737NG->737Max: 換engine同landing gear

機身反而無乜點換過

事前無告知航空公司，無相關訓練，無法切除。
你可以話唔係自動駕駛系統，但係一個全電腦控制而並唔打算 ...

MCAS唔係無法override，正如Lion Air單野發生前一班機果組機頭都可以override到

It is sad to hear some of the “junior investigator” talking heads make astoryline out of factoids or no facts about the 737 MAX. They embellish theircredentials to sound smart when in fact they have no clue and say thingsabout analyzing data that doesn’t exist....A good friend of mine who is a former airline captain and flight safetyprofessional ant be the following:“The VAST majority of the inane comments and knee jerk industry reactions onFB and AV Herald are based on no valid nor substantiated informationregarding the MAX aircraft.However, NO one is talking about the pilots, nor the airlines involved, northe training, nor the experience of the pilots. It IS WELL BEYOND time thatthese direct factors are understood, investigated and considered a possiblecontributor to the two distinct MAX accidents.The accident information in news articles dated 11/28/2018 indicated that theprevious crew at Lion Air had experienced the MCAS issue but CORRECTLY dealtwith it by disconnecting the stab trim cutouts - as expected in the NNC(non-normal checklist) yet the accident crew could not figure it out. Why theplane was dispatched in an unairworthy condition needs to be addressed andwhy one crew did and the accident crew did not figure it out the systemissues needs to be explored because the deficiencies with the accident flightcrew can be traced back to inadequate or deficient training and like suspectpilot qualifications!”

飛入中國領空要入紙備案，同航空公司講唔批相關申請就得。唔洗講公開。

而航空公司都應該知點做。 ...

如果大陸禁止737 MAX進入領空，SpicyJet一早在3月12日轉用737-800執飛香港航線

睇你點睇咩叫次要啦。

就係因為個機體設計無改變又要加大引擎，產生一系統改動導致產生失速的潛在風險， ...

咁可否解釋下係乜野"一系統改動導致產生失速的潛在風險"呢？
