Ingabe kuphephile ukundiza indiza yaseSouthwest Airline B737-800 isuka eNyakatho Melika iya e-Hawaii? Lona umbuzo ochwepheshe abaningi abazibuzayo kulezi zinsuku. Umkhulumeli we-Boeing uphendule wathi: "Siyenqaba ngenhlonipho ukuphawula nokubamba iqhaza endabeni yakho."

Kubukeka sengathi i-Boeing yethukile ngemuva kokuba abakwa-eTN bengabaza ukuphepha lapho besebenzisa indiza eklanyelwe izindiza ezimfushane noma ezimaphakathi zomzila omude ohamba phezu kwamanzi. I-Boeing 737 ekuqaleni yaziwa ngokuthi "i-City Jet" yezindiza ezifushane ukusuka edolobheni kuye kwelinye.

Izolo nje, I-Southwest Airlines iphethe ngempumelelo indiza nge-B737-800 yabo isuka e-Oakland, eCalifornia, iya e-Honolulu, eHawaii. Inkampani yezindiza yayidinga ukubonisa le ndiza ukuze ithole isitifiketi se-ETOPS ukuze indize phezu koLwandlekazi i-Pacific ngendiza enenjini engu-2. Ngokuvamile i-FAA idinga okungenani iminyaka engu-1.5 yokusebenza okungenazinkinga ukuze ikhiphe isitifiketi esinjalo. Lokhu kwahoxiswa kwabangu-787 ngezinye izinhlekelele eziseduze kusenesikhathi.

Indiza esuka e-LAX eya e-HNL ithatha cishe amahora angu-5 phezu kolwandle ingekho enye indawo lapho kuhlala khona ukwehluleka noma isimo esiphuthumayo. Ngakho-ke, i-737 kumele ikwazi ukuqhubeka iye e-Honolulu noma ibuyele e-LA. Kufanele ilinganiselwe yi-FAA ku-ETOPS 180, okusho ukuthi kufanele ikwazi ukundiza amahora angu-3 ngenjini eyodwa njengoba indawo emaphakathi yendiza izoba cishe amahora angu-2.5.

I-737 yaklanywa njengendiza enezinjini ezimbili ezindizeni ezimfushane nezimaphakathi ezingamamayela angu-2 2,000 noma ngaphansi, kodwa ngezinjini ezinokwethenjelwa, manje isindiza phezu kweNorth Atlantic isuka eNew York City iya e-Ireland naphezu kweGulf of Mexico. ukusuka eTampa noma e-Orlando, eFlorida, ukuya ePanama City nakwezinye izindawo zaseLatin America noma eCaribbean.

I-United Airlines iqale ukusebenza kule ndiza isuka e-US West Coast iya e-Honolulu esikhathini esithile esedlule futhi yaphoqeleka ukuthi ifake phakathi nokufika okungahleliwe e-San Francisco ezindizeni ezidayisiwe izama ukusuka e-LAX ingami ukuya e-HNL. Lokhu bekuwukuqinisekisa ukuthi kunophethiloli owanele wokuthatha indiza yonke indlela eya eHawaii. I-San Francisco ukuya e-Honolulu iyibanga eliqondile elifushane kakhulu phakathi kwe-US Mainland ne-Honolulu.

Uma kungaba khona ukwehluleka kwezinjini ezi-2 phezu kwePacific ayikho indawo yokuhlala, futhi ukusinda akunakwenzeka. Ukwehluleka kwenjini eyodwa kuyinkinga njengomlilo noma enye inkinga yemishini edinga ukuhlala okuphuthumayo; isimo phezu kwePacific singakhula konke lokhu. Iphuzu elithusayo ukuthi ngonyaka ojwayelekile, kuba nezimo eziphuthumayo ezingama-250.

Izihlalo nezindlu zokugezela ku-737 MAX ziminyene kakhulu ezindizeni ezinde futhi kuzoholela ku-DVT eyengeziwe nezinye izinkinga kubagibeli abakhuluphele noma abakhubazekile.

UPaul Hudson, uMongameli, Flyersrights.org, utshele i-eTN: “Esicabanga ukuthi kufanele kwenzeke yizihlalo ezinkulu nezimbalwa, ububanzi bukhuphule i-fuselage ukusuka kumafidi angu-11 ukuya okungenani angu-12, kanye nezindawo zokuhlalisa eziphuthumayo ezifakiwe noma ezitholakalayo phakathi kwe-glide.

Ngaphandle kwengozi ebulalayo yakamuva ye-Lion Air e-Indonesia, lapho i-Boeing Co. igodle khona ulwazi mayelana nezingozi ezingaba khona ezihlobene nesici esisha sokulawula indiza, i-Xiamen Airlines ibe nengozi ku-B737-800 e-Manila. Esinye isigameko sesabise abagibeli abangu-47 bendiza i-Air Niugini Boeing 737-800, abasinde engozini yolwandle iPacific engamayadi angu-159 eChuuk Airport, isiqhingi esincane eMicronesia.

Indiza yase-Bangladesh 737-800 ifike yahlehliswa ikhala futhi yavutha.

LOKHO ONGAKUTHATHE KULESI SIHLOKO:

I-737 yaklanywa njengendiza enezinjini ezimbili ezindizeni ezimfushane nezimaphakathi ezingamamayela angu-2 2,000 noma ngaphansi, kodwa ngezinjini ezinokwethenjelwa, manje isindiza phezu kweNorth Atlantic isuka eNew York City iya e-Ireland naphezu kweGulf of Mexico. ukusuka eTampa noma e-Orlando, eFlorida, ukuya ePanama City nakwezinye izindawo zaseLatin America noma eCaribbean.
