I-Boeing yokugcina engu-747 iphuma efekthri ngemva kweminyaka engaphezu kwengu-50 yokukhiqiza

EVERETT, Geza. − I-Boeing‘I-747 yokugcina ikhishwe efekthri yenkampani enyakatho ye-Seattle ngoLwesibili ebusuku njengezindiza’ Phusha ukuze izindiza ezonga uphethiloli ziqede ukukhiqizwa kwendiza enkulu yekhulunyaka engaphezu kwesigamu.

Eye-1,574 – neyokugcina – engu-747 ngokuhamba kwesikhathi izondiza umshayeli wendiza yokuhlola i-Boeing, ipendwe bese inikelwa kumthwali wezimpahla kanye ne-charter. Atlas Air Worldwide Holdings ekuqaleni konyaka ozayo.

“Isikhathi esinzima kakhulu, kusobala,” kusho uKim Smith, iphini likamongameli kanye nomphathi jikelele wezinhlelo ze-Boeing 747 kanye ne-767s ephuma embonini yomhlangano lapha. “Ngokokuqala ngqa eminyakeni engaphezu kwengu-50 ngeke sibe nabangu-747 kulesi sikhungo.”

I-747 eyodwa, embozwe ngengubo eluhlaza yokuzivikela, ibihlezi ngaphakathi kwemboni enkulu yenkampani e-Everett – okuyisakhiwo esikhulu kunazo zonke emhlabeni ngomthamo, ngokusho kukaBoeing. Lesi sakhiwo sakhelwe ngokukhethekile ukuqala ukukhiqizwa kwe-jumbo jet ngo-1967.

Ngaphakathi, abasebenzi be-Boeing bachithe izinsuku ezimbalwa ezedlule beshintshashintsha amagiya okufika, ukulungisa kahle izinhlelo zokuphatha impahla kanye nokuqeda ingaphakathi ngaphambi kokuthi indiza yokugcina engamafidi angu-63 ubude kanye namafidi angu-250 ubude ishiye isakhiwo. Imisila enamalogo ekhasimende athenge ingxenye yomugqa we-747 yomunye weminyango.

Ukuphela kokukhiqizwa kwe-747 akusho ukuthi izindiza zizonyamalala ngokuphelele esibhakabhakeni, njengoba ezintsha zingandiza amashumi eminyaka. Nokho, seziyivelakancane emikhunjini yezentengiselwano. I-United neDelta bavalelisa kweyabo eminyakeni edlule ubhubhane lwe-Covidngenkathi i-Qantas neBritish Airways bathola ama-747 abo ngo-2020 ngesikhathi sokwehla kohambo lomhlaba wonke.

“Bekuyindiza enhle kakhulu. Isisebenzele ngokumangalisayo,” kusho isikhulu seBritish Airways uSean Doyle eceleni komcimbi obuse-John F. Kennedy International Airport nozakwabo. Izindiza zaseMelika evikini eledlule. “Kuningi ukulangazelela nothando ngakho kodwa uma sibheka ikusasa kumayelana nezindiza zesimanje, ukusebenza kahle kakhulu, nezixazululo ezizinzile futhi.”

I-747 ene-hump-backed ingenye yezindiza ezaziwa kakhulu futhi yasiza ukwenza uhambo lwamazwe ngamazwe lufinyeleleke kalula eminyakeni yangemva kwendiza yayo yokuqala yezohwebo ngoJanuwari 1970. Izinjini zayo ezine ezinamandla zazisebenza kahle ngesikhathi sazo. Izindiza zazikwazi ukuthwala amakhulukhulu abagibeli ngesikhathi esisodwa ezindizeni ezithatha uhambo olude.

Amajethi amakhulu nawo akwenza kube lula ukundiza impahla yomoya emhlabeni jikelele, ukusiza izinkampani ukuthi zibhekane nokuthandwa kwabathengi okunzima kakhulu kuyo yonke into kusukela kogesi kuya kushizi.

Ukuphela kwendiza kuza njengoba i-Boeing isebenzela ukubuyisela unyawo ngemuva kwezingqinamba ezilandelanayo, okuhlanganisa nemiphumela yezingozi ezimbili eziyingozi zezindiza zayo ezidayisa kakhulu i-737 Max ezinomzimba omncane obulale abantu abangu-346.

Ukwehla kwezinga lokuhamba kobhubhane sekudale ukwanda kwama-oda ezindiza ezintsha, kepha izinkinga zokukhiqiza zibambezele ukulethwa kwe-Boeing’s wide-body 787 Dreamliners. Inkampani ayilindele ukuthi i-777X, indiza entsha enkulu kunazo zonke, ilungele amakhasimende kuze kube sekuqaleni kuka-2025. Kusafanele futhi ilethe ama-747 amabili azosebenza njenge-Air Force One, kodwa lawo ahlaselwe ukubambezeleka. kanye nokweqa kwezindleko kanjalo.

Amasheya e-Boeing ehle cishe ngo-8% kulo nyaka kuze kube sekupheleni kwangoMsombuluko, uma kuqhathaniswa nokwehla cishe ngo-16% emakethe ebanzi. Ngaphandle kokulahlekelwa kwakamuva, isitoko sikaBoeing senyuke cishe ngo-53% kuze kube manje kule kota. Uhlelo lwe-United lokuthenga inqwaba yama-Dreamliners, okungenzeka ekupheleni konyaka, lusize ekunyuseni amasheya.

Isikhulu sakwaBoeing uDave Calhoun ngenyanga edlule wathi “kuzoba nesikhashana lapho sizokhipha unogwaja esigqokweni bese sethula indiza entsha phakathi neminyaka eyishumi ezayo,” wathi ubuchwepheshe budinga ukunikeza uphethiloli owengeziwe. ukonga.

Ukuphela kokukhiqizwa kwe-747 “kwakungenakugwenywa kodwa bekungaba mnandi kakhulu uma benza okuthile okusha,” kusho u-Richard Aboulafia, umqondisi ophethe enkampanini yokubonisana ye-AeroDynamic Advisory.

Kuzo zonke izigigaba zayo izindiza zezindiza kudala zifuna izindiza ezonga uphethiloli. I-twin-aisle yakwa-Boeing kanye ne-twin-engine 777s kanye nama-787 Dreamliners athathe indawo ephambili kanye nezimbangi zakhe ezinkulu i-Airbus.

Izinkampani zezindiza ziye zawagwema kakhulu amajethi anenjini ezine ukuze zithole indawo yezindiza ezinenjini ezimbili.

“Isitha esikhulu sama-Boeing quads bekungamawele e-Boeing,” kusho u-Aboulafia.

I-Airbus, nayo, isiqedile ukukhiqiza i-Airbus A380 yayo ngemuva kokugijima iminyaka engu-14, inikezela ngendiza yokugcina enkulukazi emhlabeni ngonyaka odlule. Lawa majethi amakhulu enzelwe ukuhambisa abagibeli ezikhumulweni zezindiza, kodwa abahambi bavame ukufuna imizila emifushane ngezindiza ezingami.

Ngo-1990, bekunama-Boeing 747 angama-542 akha u-28% wemikhumbi yabagibeli emhlabeni wonke, ngokusho kwe-AeroDynamic Advisory, ecaphuna i-Center for Aviation data. Njengoba kunezindiza ezingu-109 ze-Boeing 747, amajethi abalelwa ku-2% kuphela wemikhumbi yabagibeli emhlabeni wonke kulo nyaka, ngokusho kwe-CAPA.

Ukubusa kwendiza emakethe yezimpahla zomoya nakho sekunciphile, njengoba nje impahla yomoya yavela njengendawo ekhanyayo ngesikhathi sodlame. Ama-747 ahlanganisa u-21% wemikhumbi ethwala impahla yomhlaba wonke, ehle isuka ku-71% ngo-1990, ngokusho kwe-CAPA. I-Airbus isiqalile ukumaketha inguqulo ethwala impahla yembangi yayo ebanzi i-A350 kanti i-Boeing ithengisa inguqulo ye-777X, njengoba izinkampani zezindiza zilungiselela amazinga aqinile okukhipha umoya.

Onjiniyela, omakhenikha nabanye abasebenze ku-747 bazodlulela kwezinye izinhlelo zendiza njengoba umenzi ezama ukukhuphula umkhiqizo, kusho uSmith.

“Lezo zinhlelo zizimisele kakhulu futhi zifana nokuwisa umnyango wethu ukuze sithole leli zinga lekhono eliphezulu ukuthi lijoyine iqembu labo,” kusho yena.
