Umqhubi wenqwelomoya, ochongwe kuphela njengo 'Pilot X' kumaxwebhu asenkundleni, waqala ityala elichasene neBoeing, etyhola umenzi wenqwelomoya wase-US ngokufihla umba we-737 MAX's sensor ephosakeleyo kunye nokugcina abaqhubi beenqwelo moya ebumnyameni malunga nenqaku ekusukeleni ukubuya ngokukhawuleza.
Intshukumo yezomthetho yajoyinwa ngaphezulu kwe-400 yabaqhubi beenqwelomoya, abaqeqeshelwa ukubhabha isizukulwana sesine-somzimba omxinwa 737 MAX moya. Batyhola iqumrhu elisebenza ngenqwelomoya elisebenza eChicago ngokugcina izinto ezixhalabisayo malunga nezixhobo ezigcwele glitch ezifakwe kwiijets.
Ingxaki ephambili yeejethi igxilwe "kwiiphene zokuphatha i-aerodynamic eyingozi" ye-Maneuvering Characteristics Augmentation System (MCAS), eyenzelwe ukukhusela indiza ekumiseni. Ukusebenza kwayo ngokugudileyo kuxhomekeke kwidatha eyifumanayo evela kwi-Angle of Attack (AoA) ezimbini zezilumkiso. Zimbini zazo ngesizathu: ukuba idatha evela kubenzi boluvo ayihambelani, isilumkiso se-AoA sokungavumelani kufuneka sikhanyise, sazise abaqhubi beenqwelo moya ngokungangqinelani.
Ukuze le yokugqibela isebenze ngokufanelekileyo, kufuneka kusetyenziswe izikhombisi-ndlela ezikhethiweyo kwisikhululo senqwelomoya, kwaye zingama-20% kuphela eejetshi ezingama-737 MAX ezazinazo. U-Boeing kutshanje uvumile ukuba uyayazi ingxaki ukusukela ubuncinci i-2017, kodwa akazange azise i-US Federal Aviation Authority (i-FAA) kude kube semva kokuba inqwelomoya yeLion Air inabantu abangama-189 ababekhwele e-Indonesia ngo-Okthobha ophelileyo. Ngapha koko, khange icwangcise ukuhlaziya isoftware kude kube ngu-2020.
Ityala, elifuna imbuyekezo yomvuzo olahlekileyo kunye nokubandezeleka kwengqondo abaqhubi beenqwelomoya abakunyamezeleyo ngenxa yomhlaba, ityhola ukuba ingxilimbela yezomkhosi bekufanele ukuba yazi ukuba ngokutshayela umba phantsi kombhoxo, ibeke inqanaba lesiphumo kanye.
Isikhalazo sithi iBoeing "yazigquma ngendlela engazange ibonwe ngaphambili kweziphene eziyiliweyo ze-MAX, ezikhokelele kwingozi yeenqwelo-moya ezimbini ze-MAX kunye nokusekwa kwazo zonke iinqwelomoya ze-MAX kwihlabathi liphela."
Abaqhubi beenqwelomoya "bayasokola kwaye bayaqhubeka nokufumana umvuzo ophulukene kakhulu, phakathi komonakalo wezoqoqosho nakwezoqoqosho."
Ukongeza, abaqhubi beenqwelo moya batyhola iBoeing ngokubonelela ngemiyalelo emincinci malunga nendlela yokuphatha inqaku elichasayo, elikhankanywe ngokufutshane kwiincwadana zokubaleka. Batyhola ngelithi indlela engaqhelekanga yokuqhelanisa abaqhubi beenqwelo-moya ngesoftware entsha yayenziwe ngabom- kwaye yayenzelwe ukonga iindleko zokuzisa uqeqesho olusekwe kwisimulator ukuze abaqhubi beenqwelomoya bathathe "iindlela zokwenza ingeniso ngokukhawuleza."
Abamangali bathi eyona njongo yabo iphambili kukuthintela iintlekele ezinje ngengozi yeLion Air kunye ne-Atiopian Airlines, ethi yabulala abantu abangama-346, ukuba ingenzeki kwixesha elizayo ngokunqanda "iBoeing kunye nabanye abenzi beenqwelo moya ekubekeni inzuzo yequmrhu phambi kobomi babaqhubi beenqwelo moya. , abasebenzi, nenkonzo yoluntu ngokubanzi. ”
Ityala liya kumanyelwa yinkundla yaseChicago ngo-Okthobha.
