Isu takashuma matambudziko neMCAS (Maneuvering Characteristics Augmentation System), iyo yakagadzirirwa kubatsira chinyararire vatyairi vendege kubhururuka Boeing 737 Max ndege mune yemanyorero mode (apo autopilot yakadzimwa). Zvinotendwa kuti ndiye akatungamira kune tsaona mbiri dzekupedzisira dzendege nemuchina uyu. Munguva pfupi yapfuura, US Federal Aviation Administration (FAA) yakatumira chigamba chesoftware chakagadzirwa nenyanzvi dzeBoeing kuti chidzokororwe, kuitira kuti ndege dzisasimuka kwenguva yakareba kunyangwe pamusoro peAmerica. Kuferefetwa kuri kuenderera mberi nezve tsaona yeEthiopiya Boeing munaKurume 10, uye Reuters, ichitaura kwairi kubva, yakashuma kuti MCAS system yakavhurwa zvakare mushure mekunge vatyairi vadzima, ndokuisa ndege mukunyura.
Matunhu maviri akati mushumo wekutanga wekuEthiopiya pamusoro pekuparara uku unofanirwa kuburitswa mukati memazuva uye unogona kusanganisira humbowo hwekuti MCAS system yakaitwa kanokwana kana 737 Max isati yarova pasi. Gweta rechitatu rakaudza vatori venhau kuti software yakatanga zvakare mushure mekunge vatyairi vadzima, asi vakawedzera kuti paingova nechikamu chimwe chete chakakosha umo MCAS yakaisa ndege mukunyura kusati kwaitika. Zvinonzi, software yakatanga kushanda zvakare pasina kupindira kwevanhu.
Mukutaura kune vatori venhau nezve data, Boeing akati: "Tinokurudzira kuchenjerera uye kusaita fungidziro kana kutora mhedziso pamusoro pezvabuda data rendege uye mushumo wekutanga waburitswa." Parizvino MCAS ndiyo iri pakati penyaya yetsaona yeEthiopian Flight 302 uye tsaona yeLion Air kuIndonesia mwedzi mishanu yapfuura - tsaona dzakauraya vanhu mazana matatu nemakumi mana nevatanhatu.
Matanho akakwira: Boeing 737 Max ndiyo ndege inotengeswa zvakanyanya nekambani, ine maodha anoda kusvika zviuru zvishanu. Uye ikozvino boka rendege dzinotengeswa rinoramba richigara pasi rose risina basa. Kutangwazve kwendege kunoenderana nebasa rakaitwa nemagadzirirwo endege pakuparara, kunyangwe vaongorori vari kutarisawo zvakaitwa nemakambani endege, vashandi pamwe nematanho ekudzora. Boeing iri kutsvaga kuvandudza software yayo yeMCAS uye kuunza zvirongwa zvitsva zvekudzidzisa vatyairi.
Zvakambotaurwa kuti mukupunzika kwese kuri kuviri dambudziko rinogona kunge rine chekuita nekushanda kwakashata kweMCAS, iyo yakatungamirwa neinotadza kona yedata rekurwisa kubva kune imwe yemasensa maviri endege. Ikozvino kuferefetwa kunonzi kwakagumisa kuti muEthiopian nyaya, MCAS yakatanga yakaremara zvakafanira nevatyairi vendege, asi ndokuzotangazve kutumira otomatiki mirairo kune stabilizer, iyo yakaisa ndege mukunyura.
Kutevera tsaona yeIndonesia, Boeing yakapa mirairo kune vatyairi vachitsanangura maitiro ekudzima MCAS. Zvinoda kuti mushure mekuvhara uye kusvika pakupera kwendege vashandi havatenderi iyi system. Bepanhau reWall Street Journal rakambotaura kuti vatyairi vendege vakambotevedzera nzira dzeBoeing dzechimbichimbi asi vakazozvisiya pavakaedza kudzora ndege. Kudzima hurongwa kunonzi hakuregi zvachose MCAS, asi kunotyora kubatana pakati pesoftware, iyo inoramba ichiburitsa mirairo isiriyo kune stabilizer, uye kutonga chaiko kwendege. Vatsvagiri vari kuferefeta kana paine chero mamiriro ekuti MCAS inogona kuita otomatiki pasina ruzivo rwevatyairi.
Muongorori Bjorn Fehrm akakurudzira mubhurogi rake kuti vatyairi vendege vanogona kunge vakatadza kubvisa nemaoko iyo stabilizer kubva panzvimbo yekudhivha. Saka vanogona kunge vakafunga kumutsiridza MCAS kuyedza kuita kuti stabilizer iite pachinzvimbo, uye sisitimu yacho haina kuvabvumira kuzviita. Nyanzvi dzezvekuchengetedza, zvisinei, dzinosimbisa kuti kuferefeta kuri kure nekupedzwa, uye tsaona zhinji dzendege dzinokonzerwa nekubatanidzwa kwezvinhu zvevanhu uye zvehunyanzvi.
