Sichaze iingxaki kunye ne-MCAS (iNkqubo yoKwandisa iimpawu zeManeuvering Characteristics), eyilelwe ukunceda abaqhubi beenqwelo moya ngokuzolileyo babhabhe inqwelomoya ye-Boeing 737 Max kwimo yezandla (xa i-autopilot icinyiwe). Kukholelwa ukuba nguye owakhokelela kwiingozi ezimbini zokugqibela zenqwelomoya ngalo matshini. Kutshanje, i-US Federal Aviation Administration (FAA) ithumele isiqwenga sesoftware esenziwe ziingcali ze-Boeing ukuze zihlaziywe, ukuze iinqwelomoya zingahambi ixesha elide nakwiMelika. Uphando luyaqhubeka ngoku kwingozi ye-Boeing yase-Ethiopia ngo-Matshi 10, kwaye iReuters, ikhankanya imithombo yayo, ibike ukuba inkqubo ye-MCAS yaphinda yasebenza emva kokuba abaqhubi beenqwelo-moya beyicimile, kwaye bafaka indiza kwi-dive.
Imithombo emibini ithe ingxelo yokuqala yase-Ethiopia malunga nengozi kufuneka ikhutshwe ngaphakathi kweentsuku kwaye inokubandakanya ubungqina bokuba inkqubo ye-MCAS yenziwe yasebenza kangangezihlandlo ezine ngaphambi kokuba i-737 Max ifike emhlabeni. Umthombo wesithathu uxelele iintatheli ukuba isoftware yaqala kwakhona emva kokuba abaqhubi beenqwelomoya beyicimile, kodwa yongeza ukuba kukho isiqendu esinye esibalulekileyo apho i-MCAS yabeka inqwelomoya ukuba idive ngaphambi kwengozi. Ngokucacileyo, isoftware yaqala ukusebenza kwakhona ngaphandle kokungenelela komntu.
Kwisiteyitimenti kwiintatheli malunga nedatha, uBoeing uthe: "Sibongoza ukuba silumke kwaye singenzi ingcinga okanye senze izigqibo malunga neziphumo ngaphambi kokuba idatha yendiza kunye nengxelo yokuqala ikhutshwe." Inkqubo ye-MCAS okwangoku isembindini wehlazo elijikeleze ingozi ye-Ethiopian Flight 302 kunye nengozi yeLion Air e-Indonesia kwiinyanga ezintlanu ezidlulileyo-ingozi ezibulele abantu abangama-346 bebonke.
Amanani aphezulu: I-Boeing 737 Max yeyona nqwelo-moya ithengiswa kakhulu kwinkampani, ene-odolo ephantse ibe ngama-5000. Kwaye ngoku iinqwelomoya ezithengiswayo ziyaqhubeka nokuhlala zingasebenzi kwihlabathi jikelele. Ukuqaliswa kwakhona kweenqwelo-moya kuxhomekeke kwindima edlalwe luyilo lwenqwelo-moya kwingozi, nangona abaphandi bajongana nezenzo zeenqwelomoya, abasebenzi kunye namanyathelo olawulo. I-Boeing ijonge ukuhlaziya isoftware yayo ye-MCAS kwaye yazise iinkqubo ezintsha zoqeqesho lokulinga.
Ngaphambili kwakuxelwe ukuba kuzo zombini iingozi ingxaki inokunxulumana nokusebenza okungalunganga kwe-MCAS, eyayikhokelwa yi-angle ephosakeleyo yokuhlaselwa kwedatha evela kwenye yezinzwa ezimbini zenqwelomoya. Ngoku uphando kuthiwa lugqibe ukuba kwimeko yaseTopiya, i-MCAS ekuqaleni ikhubazwe ngokufanelekileyo ngabaqhubi beenqwelo-moya, kodwa yaphinda yaqala ukuthumela imiyalelo ezenzekelayo kwi-stabilizer, ebeka indiza kwi-dive.
Ukulandela ingozi yase-Indonesia, i-Boeing ikhuphe imiyalelo kubaqhubi beenqwelo-moya echaza inkqubo yokuvala i-MCAS. Ifuna ukuba emva kokuvalwa kwenqwelomoya kwaye kude kube sekupheleni kwenqwelomoya abasebenzi bangavuli le nkqubo. IWall Street Journal ngaphambili yaxela ukuba abaqhubi beenqwelomoya baqale balandela iinkqubo zikaBoeing ezingxamisekileyo kodwa kamva babashiya njengoko babezama ukuphinda balawule inqwelomoya. Ukukhubaza inkqubo kuthiwa akuyi kumisa ngokupheleleyo i-MCAS, kodwa iyaphula uxhulumaniso phakathi kwesoftware, eqhubeka nokukhupha imiyalelo engachanekanga kwi-stabilizer, kunye nolawulo lwangempela lwenqwelomoya. Abaphandi ngoku bayaphanda ukuba ingaba zikhona na iimeko apho i-MCAS inokuvuselela ngokuzenzekelayo ngaphandle kolwazi lwabaqhubi.
Umhlalutyi uBjorn Fehrm ucebise kwibhlog yakhe ukuba abaqhubi beenqwelomoya banokuthi basilele ukususa ngesandla i-stabilizer kwindawo yokuntywila. Ke banokuthi bagqibe ekubeni baphinde bavule i-MCAS ukuze bazame ukwenza uzinzo kwindawo, kwaye inkqubo ayikhange ibavumele bayenze loo nto. Iingcali zokhuseleko, nangona kunjalo, zigxininisa ukuba uphando lusekude ukuba lugqitywe, kwaye iingozi ezininzi zeenqwelomoya zibangelwa yintlanganisela yabantu kunye nezobugcisa.
