Ngaba kukhuselekile ukuhamba ngenqwelomoya kwinqwelomoya ye-B737-800 ukusuka eMntla Melika ukuya eHawaii? Lo ngumbuzo uninzi lweengcali lubuza kule mihla. Isithethi seBoeing siphendule sathi: “Ngentlonipho siyala ukuphawula nokuthatha inxaxheba kwibali lakho.”

Kubonakala ngathi iBoeing yathathelwa indawo emva kokuba i-eTN ibuze ngokhuseleko xa isebenzisa inqwelomoya eyilelwe ukuhamba moya okufutshane kunye nokuhamba ngenqwelomoya kwindlela ende yokuhamba ngaphezulu kwamanzi. I-Boeing 737 ekuqaleni yayisaziwa njenge- "City Jet" ngeenqwelo-moya ezihamba umgama omfutshane ukuya esixekweni.

Izolo nje, Iinqwelomoya zase Mzantsi-ntshona zigqibe ngempumelelo Ukuhamba ngenqwelomoya kwi-B737-800 yabo ukusuka e-Oakland, California, ukuya e-Honolulu, eHawaii. I-airline kufuneka ibonise lo moya ngenqwelomoya ukuze ifumane isatifikethi se-ETOPS sokubhabha ngaphezulu koLwandlekazi lwePasifiki ngenqwelomoya enenjini ezimbini. Ngokwesiqhelo i-FAA ifuna ubuncinci iminyaka eyi-2 yokusebenza ngaphandle kwengxaki ukukhupha isatifikethi. Oku kuye kwarhoxiswa ama-1.5 ezinye zazikufutshane neentlekele kwasekuqaleni.

Ukubhabha ngenqwelomoya ukusuka kwi-LAX ukuya kwi-HNL kuthatha malunga neeyure ezi-5 ngaphezulu kolwandle kungekho ndawo yimbi yokumisa kwimeko yokusilela okanye imeko kaxakeka. Ke, i-737 kufuneka ikwazi ukuqhubekeka ne-Honolulu okanye ibuyele e-LA. Kuya kufuneka ukuba ikalwe yi-FAA ye-ETOPS 180, oko kuthetha ukuba kuya kufuneka ikwazi ukubhabha iiyure ezi-3 kwinjini enye ukusukela kwinqanaba lendiza eliza kuba malunga neeyure eziyi-2.5.

I-737 yenzelwe inqwelomoya eneenjini ezimbini ukuhamba iinqwelo-moya ezimfutshane neziphakathi ezihamba umgama oziikhilomitha ezingama-2 2,000 okanye ngaphantsi, kodwa iinjini ezinokuthenjwa, ngoku ibhabha kuMntla weAtlantic ukusuka kwisiXeko saseNew York ukuya eIreland naseGulf of Mexico. ukusuka eTampa okanye eOrlando, eFlorida, ukuya kwisiXeko iPanama nakwezinye iindawo ezikwiLatin America okanye kwiCaribbean.

I-United Airlines iqale ukusebenza kule nqwelo-moya isuka kwi-West Coast yase-US yaya e-Honolulu kwithuba elidlulileyo kwaye yanyanzelwa ukuba ibandakanye ukufika okungacwangciswanga eSan Francisco kwiinqwelomoya ezithengisiweyo zizama ukuyenza ukusuka kwi-LAX ingamisi iye kwi-HNL. Oku yayikukuqinisekisa ukuba kukho ipetroli eyaneleyo yokuthatha inqwelo moya ukuya eHawaii. ISan Francisco ukuya eHonolulu ngowona mfutshane umgama ngqo phakathi kwe-US Mainland kunye ne-Honolulu.

Ukuba kuyakubakho ukusilela kwe-2-injini ngaphezulu kwePasifiki akukho ndawo yomhlaba, kwaye ukusinda akunakulindeleka. Ukusilela kwenjini enye kuyingxaki njengoko kunjalo ngomlilo okanye ngomnye umba womatshini ofuna ukumiswa ngokungxamisekileyo; imeko kwiPasifiki iya kunyusa yonke le nto. Inqaku eloyikisayo kukuba kunyaka oqhelekileyo, kukho ama-250 okufika ngokungxamisekileyo.

Ukuhlala kunye neendawo zokuhlambela kwi-737 MAX zixinene kakhulu kwiinqwelomoya kwaye kuya kukhokelela kwi-DVT kunye neminye imiba yabakhulu okanye abagibeli abakhubazekileyo.

UPaul Hudson, Mongameli, Ilungelo lokufunda.org, uxelele i-eTN: "Into esicinga ukuba kufuneka yenzeke inkulu kwaye kunezihlalo ezimbalwa, kwandiswe ububanzi be-fuselage ukusuka kwi-11 ukuya kwi-12 yeenyawo ubuncinci, kunye neendawo zokufika ngokungxamisekileyo ezifakiweyo okanye ezifumanekayo ngaphakathi kuluhlu lwe-glide.

Ngaphandle kwengozi eyenzeke kutshanje yeLion Air eIndonesia, apho iBoeing Co. ibambe ulwazi malunga neengozi ezinokubakho ezinxulumene nolawulo olutsha lwenqwelomoya, iXiamen Airlines iye yaphazanyiswa yiB737-800 eManila. Esinye isiganeko esoyikisa abakhweli abangama-47 kwiAir Niugini Boeing 737-800, abasindayo kwingozi yoLwandlekazi lwePasifiki iiyadi ezili-159 zesikhululo senqwelomoya iChuuk, isiqithi esincinci eMicronesia.

Inqwelomoya ye-Bangladesh 737-800 yeza ngeempumlo zarhoxiswa zaza zatsha.

INTO ONOKUYITHATHA KWELI NQAKU:

I-737 yenzelwe inqwelomoya eneenjini ezimbini ukuhamba iinqwelo-moya ezimfutshane neziphakathi ezihamba umgama oziikhilomitha ezingama-2 2,000 okanye ngaphantsi, kodwa iinjini ezinokuthenjwa, ngoku ibhabha kuMntla weAtlantic ukusuka kwisiXeko saseNew York ukuya eIreland naseGulf of Mexico. ukusuka eTampa okanye eOrlando, eFlorida, ukuya kwisiXeko iPanama nakwezinye iindawo ezikwiLatin America okanye kwiCaribbean.
Kufuneka inikwe ireyithingi ye-FAA ye-ETOPS 180, okuthetha ukuba kufuneka ikwazi ukubhabha iiyure ezi-3 kwi-injini enye kuba umbindi wenqwelomoya uya kuba malunga ne-2.
Inqwelomoya esuka kwi-LAX isiya kwi-HNL ithatha malunga neeyure ezi-5 phezu kolwandle kungekho ndawo yokuma eyenye xa kukho ukusilela okanye kukho imeko kaxakeka.
