Ubulumko obuqhelekileyo buthetha ukuba iinqwelomoya kufuneka zibeke iinqwelomoya ezinomzimba omxinwa kuphela kwiindlela zasekhaya kwaye zisebenzise iijets ezinkulu zomzimba ukubhabha iindlela zamanye amazwe.
Nangona kunjalo, loo nto inokuba yingxaki xa inqwelomoya yakho encinci ye-Atlantic yiBoeing 767, inezihlalo ezingama-225, kwaye uneendlela ezingakwaziyo ukuxhasa abantu abaninzi.
Injalo imeko yeAmerican Airlines Inc., impendulo yayo, njengoko ibiyinani leenqwelo moya, kukuhlaziya ezona zincinci, i-single-aisle Boeing 757s ndizibeke kwiindlela ezimfutshane zamazwe aphesheya.
I-American yase-Fort Worth esekwe yaqala ukubhabha iinqwelomoya zokuqala eziyi-18 ze-Boeing 757-200, ezinamashishini amatsha kunye neeklasi zoqoqosho, kwindlela yayo eNew York-Brussels ngoLwesine, indlela eyayikade iqhutywa ngumzimba wayo iBoeing 767- Ngama-300.
Umerika uthi ezinye iindlela ezisebenzisa iBoeing 757 zinokubandakanya iinqwelomoya zaseNew York eziya eBarcelona, eSpain naseParis; IBoston ukuya eParis; kunye neMiami baya eSalvador, eBrazil, inqwelomoya eya eRecife, eBrazil.
Usihlalo waseMelika kunye ne-AMR Corp. kunye nomphathi omkhulu uGerard Arpey uthe i-757s eyakhiwe ngokutsha izakusetyenziswa kwi-Northeast kwezinye zeemarike ezincinci zaseYurophu naseMiami ukuya kwezinye izixeko ezikumantla oMzantsi Melika.
Igosa eliyintloko lezezimali e-AMR uTom Horton uthe kumvuzo wenkampani fowunela umhla we-15 ku-Epreli ukuba i-757 emiselweyo kwakhona iya kusetyenziselwa ukubuyisela iinqwelomoya ezinkulu kwiindlela esele zikho kunye "nokubhabha okutsha okutsha. Iya kuba yimveliso entle kakhulu. Siza kuba nesitayile sokwenyani kwiklasi yokuqala, eza kwahlula kwezinye ezihamba ngenqwelomoya kangange-757s. ”
Ii-124 ze-Boeing 757 zaseMelika zihlala ziqwalaselwe ngezihlalo eziyi-188 - izihlalo ezingama-22 zeklasi yoshishino kunye nezihlalo ezili-166 kwiklasi yezoqoqosho. Kodwa ii-757 zamazwe aphesheya zinezihlalo ezili-182 kuphela, zine-16 kuphela kudidi lweshishini.
I-18 eguqulwayo yenqwelomoya yenqwelomoya iphinda yaqwalaselwa kwakhona sisihlalo esitsha, iiTV ezinamacala asecaleni zithatha indawo yezimonitha zakudala, izindlu zangasese ezintsha kunye nenkqubo yolonwabo ebhabha kamnandi. Ababini ngoku bagqityiwe, kunye neenqwelomoya esele zisafuneka ziphinde zenziwe kwakhona ngasekupheleni kuka-2009.
I-American ayisiyiyo eyokuqala okanye ayisiyongcwangu ekusebenziseni iBoeing 757s ukubhabha iye eYurophu.
I-Continental Airlines Inc. ibhabha isuka eNewark, NJ, hub ukuya kwizixeko ezili-19 zaseYurophu, kubandakanya izixeko ezibini ngaphezulu kweekhilomitha ezingama-3,900 kude: IStockholm neBerlin.
I-Delta Air Lines Inc. ikwaxhomekeke kwi-Boeing 757 yokwandisa inkqubo yayo esuka eNew York, yongeza iidolophu zaseYurophu nase-Afrika. Nkqu neMelika ibaleke iBoeing 757s isiya eYurophu kwixa elidlulileyo, ezinje ngeNew York neManchester, eNgilane, ngo-1995.
Umcebisi wenqwelomoya waseMiami uStuart Klaskin uthe abantu baseMelika nabanye baye babhabha ngemizimba emxinwa besiya eLatin America, nkqu nase Mzantsi Melika, iminyaka elishumi.
Usebenzisa iinqwelomoya ezincinci zivumela abathwali ukuba basebenze "ngeendlela ezinde, ezibhityileyo" ezingakwaziyo ukuxhasa inqwelomoya enkulu, utshilo uKlaskin.
Ngamanye amaxesha, isenokuba yindlela apho ukugcwala kwabo kunqabileyo, okanye indlela entsha eya kwisixeko saseYurophu esincinci kakhulu ukuxhasa iBoeing 767s, iBoeing 777s, iiAirbus A330s okanye iiAirbus A340s ezenza uninzi lweshishini laseMelika izithuthi ezibanzi.
"Ngokwenene yindlela entsha yokugcina nokulolonga inkqubo yeendlela zamanye amazwe: ukubeka inqwelomoya encinci kwindawo ebekufanele ukuba yimarike yomzimba wonke," utshilo uKlaskin.
Ngokwesiqhelo, inqwelomoya iyabhabha iBoeing 767-300 egcwele abakhweli ngexabiso eliphantsi ngomkhweli ngamnye kuneBoeing 757-200 egcwele abakhweli. Nangona kunjalo, phantse i-757-200 epheleleyo enabasebenzi abancinci abatshisa amafutha amancinci angenza uhambo lube noqoqosho ngakumbi kune-767-300 ngenani elifanayo labakhweli.
"Ivumela inqwelo moya ukuba igcine inkonzo ngaphandle kokulahlekelwa yimali, okanye ingaphulukani nemali eninzi kwimeko yanamhlanje," utshilo uKlaskin.
Enye into ebuyela umva ekusebenziseni i-Boeing 757s kukuba abahambi abaninzi bakhetha inqwelomoya yomzimba, becinga ukuba ikhululekile kunenqwelo moya enye enjengeBoeing 757, utshilo uKlaskin.
Akaqinisekanga kangako. Ii-757 zinabakhweli abambalwa kwaye akukho kholamu iphakathi igcweleyo yezihlalo kwicandelo lezoqoqosho.
Amacandelo eklasi yeshishini ngaphambili kufanelekile ukuba alunge ngokulinganayo kumzimba obanzi okanye kumzimba omxinwa, utshilo.
"Ndicinga ukuba kweyona meko imbi kakhulu, iinqwelomoya azonwabanga ngokufanayo kumqeqeshi."
