Avo vanotevera zviri kuitika muindasitiri yezvendege vanoziva kunyomba kuri kuitika paBoeing 737 Max. Iyi yazvino vhezheni yendege yekambani yakakurumbira yeAmerica Boeing yaive nematambudziko akati wandei anokonzerwa nemaitiro ekugadzirwa kwendege yatove yechinyakare uye yakapetwa nguva yemazuva ano (yakagadzirwa kubva 1967). Injini itsva dzine simba uye dzakanyanya kushanda dzaive dzakakura uye dzairema zvichienzaniswa nedzakashandiswa mumuenzaniso we737 NG yapfuura uye, dzichiendeswa kure nemapapiro, dzakagadzira torque yakasimba, ichisimudza mhino yendege kana ichiwedzera kukanda. Mukuwedzera, sezvo kona yekurwisa inowedzera, inovhara kuyerera kwemhepo kumapapiro, iyo inoderedza zvakanyanya kusimudza uye ine ngozi zvikuru.
Kuti urambe uchishandisa injini itsva pamwe chete nedhizaini yekare, kambani yakauya neMCAS (Maneuvering Characteristics Augmentation System) system, iyo yakagadzirirwa kubatsira chinyararire mutyairi kudzora ndege mumanyorero maitiro (apo autopilot yadzimwa) . Kana imwe kona yekurwisa ikapfuudzwa (zvichienderana nekuverenga kwemasensa maviri), ndege inopinda mudhivha.
Dambudziko nderekuti masensa anogona kunge aine mhosva, uye MCAS yakanga isina kunyatso kunyorwa, saka vatyairi vendege havana kungoziva nezvehuvepo hwayo (hapana chakaudzwa kune vashandi apo sisitimu yakaitwa). Mukuwedzera, sezvazvakazoitika, iyo system yakatora kuverenga kubva kune imwe chete sensor. Zvinotendwa kuti kwaive kutadza kushanda kweMCAS kwakaparadza Indonesian Max muna Gumiguru uye zvakakonzera njodzi yakafanana muEthiopia munaKurume, mushure mezvo Boeing yakamanikidzwa kumisa kugadzirwa kweBoeing 737 Max.
Ikozvino iyo ine chiremera sosi The Wall Street Journal, ichitaura kwairi kubva, yakashuma kuti mugadziri wendege wekuAmerica akagadzirira kuendesa shanduko huru dzakagadzirirwa kugadzirisa kukanganisa kweMCAS system. Nekudaro, mibvunzo yasara pamusoro pekuti hurongwa hwakadaro hwakasimbiswa sei pakutanga. Aimbova mukuru weUS National Transportation Safety Board (NTSB) anotenda kuti chitupa chendege kuUS Federal Aviation Administration (FAA) mumakore achangopfuura chakaitwa nevashandi vevagadziri vendege ivo pachavo, vachifuratira zvikanganiso.
Iye zvino 737 Max ndege hadzina basa kutenderera pasirese, uye ndege dziri kurasikirwa. FAA inonzi yakatopa mvumo yekutanga kune shanduko dzakarongwa neBoeing, izvo zvinofanirwa kudzivirira njodzi huru dzakadai. Izvi zvinosanganisira software yekuvandudza iyo inopfavisa MCAS kuitira kuti vatyairi vagone kuikunda (panzvimbo peimwe nzira yakatenderedza). Iyo yekuvandudza inozodawo MCAS kuti ifunge nezve data kubva kumasensa maviri, pane imwe chete, iyo inogona kungova isina kunaka, sezvakaita munjodzi yaGumiguru.
Pamusoro pezvo, Boeing ichapa imwe dzidziso yevatyairi vendege kushandisa ndege itsva, izvo zvaisada pakutanga. Iyo FAA yakamboti iyo 737 Max ine maitiro akafanana ekubata nendege dzemhuri 737 uye haidi kuwedzera kudzidziswa kwevashandi. Iye zvino FAA iri kupomerwa mhosva yekutadza kwakakonzera mazana ekufa. Asi kunyangwe shanduko idzi dzikazobvumidzwa, zvinotora mavhiki akati wandei kugadzirisa software pandege dzese dzakagadzirwa uye mwedzi kuti dzipfuure ongororo. Uye izvi zviri muUSA chete. FAA vanobatana muCanada neEuropean Union vachaita ongororo yavo, kusanganisira neFAA chitupa chendege ine dambudziko.
Kazhinji, Boeing yave kutambura kurasikirwa kukuru kwemari uye mukurumbira. Pawebhusaiti yayo yepamutemo, kambani inoshuma kuti 737 Max ndiyo inokurumidza kutengesa ndege munhoroondo yayo: kambani yakatogamuchira anenge zviuru zvishanu odha kubva kuvatengi ve5000 pasi rese. Ndiani anoziva - pamwe kambani ichafanirwa kuenderera mberi nekugadzirwa kwechizvarwa chekare B100-NG, iyo yaifanirwa kupera pakupera kwegore rino.
