Isingeniso ku-ETOPS
I-ETOPS, isifinyezo se-Extended-range Twin-ingine Operational Performance Standards, iwuhlaka lokulawula olubalulekile kwezokundiza. Imele uchungechunge lwamazinga abekwe yi-International Civil Aviation Organisation (I-ICAO) ukubusa ukusebenza kwendiza enenjini ezimbili emizileni lapho isikhumulo sezindiza esiseduze esifanele sokufika endaweni ephuthumayo sikubude obungaphezu kwemizuzu engama-60. Umgomo wayo oyinhloko uwukuqinisekisa ukuphepha nokusebenza kahle ekusebenzeni kwezindiza ezinenjini ezimbili, ikakhulukazi leyo mizila endiza ibanga elide phezu kolwandle nasezindaweni ezikude zomhlaba.
Imithetho Yamazinga Okusebenza Okusebenza Kwenjini Enwetshiwe yobubanzi obunwetshiwe inikeza inetha yokuphepha, iqinisekisa ukuthi ngisho noma injini eyodwa yehluleka, indiza isengakwazi ukundiza ngenjini esele iye kwesinye sezindiza esifanelekile. Lo mthetho, ongase ubonakale ulula ekuqaleni, unomthelela omkhulu embonini yezindiza, ube nomthelela ekwakhiweni kwezindiza, izinqubo zokunakekela, ukuhlela indiza, kanye nezomnotho zezinkampani zezindiza.
Lo mqondo wavela ngenxa yesidingo, uqhutshwa ukuthuthuka kobuchwepheshe kanye nesidingo esikhula njalo sokuhamba ngendiza okuthatha isikhathi eside. Ezigabeni ezilandelayo, sizocubungula ngokujulile umlando, ukuqonda, ukubaluleka, kanye nomthelela embonini yezokundiza.
Umlando Wemithethonqubo ye-ETOPS
Umsuka ungalandelelwa emuva kuma-1950s, isikhathi lapho izindiza eziningi zezentengiselwano bekungamajethi ama-quad, okusho ukuthi zinezinjini ezine. Lezi zindiza zazibhekwa njengeziphephile uma zihamba ibanga elide phezu kolwandle nasezindaweni ezikude ngoba uma injini eyodwa ingaphumeleli, ezintathu ezisele zingakwazi ukugcina indiza emoyeni.
Nokho, ngeminyaka yawo-1980 kwavela indiza enenjini ephindwe kabili eyonga uphethiloli, eyayikwazi ukundiza amabanga ama-quad-jets kodwa enezindleko eziphansi zokusebenza. Lezi zindiza ezintsha zabeka inselele emithethweni ekhona, okwaholela ekwethulweni kwemithethonqubo ye-Extended-range Twin-engine Operational Performance Standards yi-Federal Aviation Administration (FAA) ngo-1985. Ekuqaleni, le mithetho yayivumela lezi zindiza ukuthi zindize imizila eyayizigcina. phakathi nemizuzu engama-60 yesinye sezindiza.
Njengoba izindiza ezinenjini ezimbili zabonisa ukwethembeka kwazo, i-FAA kancane kancane yawelula umkhawulo, okokuqala kwaba yimizuzu engu-120 ngo-1988, kwase kuba imizuzu engu-180 ngo-1989. Ngo-2007, imithetho yabuye yabuyekezwa ukuze ivumele isikhathi esiphezulu sokuphambukisa esiyimizuzu engama-330 ngaphansi. izimo ezithile.
Ukuqonda Imithetho
Imithetho ye-ETOPS iphathelene ngokuyinhloko nesikhathi esiphezulu lapho indiza enenjini ezimbili ingaba khona esikhumulweni sezindiza esiseduze esifanelekile uma kwenzeka injini eyodwa yehluleka. Lokhu kubizwa ngokuthi isikhathi somdlalo futhi kuvezwa ngamaminithi. Ngokwesibonelo, indiza enesilinganiso se-ETOPS semizuzu engu-180 ingandiza imizila eyigcina phakathi nemizuzu engu-180 yesikhathi sokundiza (enjinini eyodwa) yesikhumulo sezindiza esiseduze esifanelekile.
Ukuhambisana nemithetho kuhilela okungaphezu nje kokwethembeka kwenjini yendiza. Iphinde ihlanganise izici ezinjengokutholakala kwezikhumulo zezindiza ezifanele eduze komzila, ukunganaki kwezinhlelo zendiza, izinqubo zokusebenza zenkampani yezindiza, nokuqeqeshwa kwabasebenzi.
Inkampani yezindiza efuna isitifiketi se-ETOPS sohlobo oluthile lwendiza kufanele ibonise kwabasemagunyeni ukuthi ingasebenzisa indiza ngokuphepha phakathi nesikhathi esimisiwe sokuphambukisa. Lokhu kuhilela ukuhlolwa okuqinile kanye nokuhlolwa kokusebenza nezinhlelo zendiza, kanye nokugcinwa kwenkampani yendiza nokugcinwa kwezinqubo zayo zokusebenza.
Ukubaluleka Kwezokundiza
I-ETOPS iguqule imboni yezokundiza ngokuvumela izindiza ezinenjini ezimbili ukuthi zindize imizila emide ebigcinelwe izindiza ezinenjini ezintathu nezine. Lokhu kuholele ekongeni kwezindleko ezinkulu zezinkampani zezindiza, ngenxa yokusetshenziswa kukaphethiloli okuphansi kanye nezindleko zokunakekela izindiza ezinenjini emibili.
Ngaphezu kwalokho, ivule imizila yendiza eqondile, inciphisa isikhathi sokuhamba kubagibeli. Lokhu kunenzuzo ikakhulukazi emizileni enqamula ulwandle noma enqamula ezindaweni ezikude, lapho ukutholakala kwezikhumulo zezindiza ezifanele kulinganiselwe.
Ngokombono wokuphepha, kuye kwaholela ezindinganisweni eziqinile zokuklama, ukunakekelwa, nokusebenza kwendiza. Lokhu akugcinanga nje ngokuthuthukisa ukwethembeka kwendiza enenjini ezimbili kodwa futhi kwathuthukisa ukuphepha kukonke kokuhamba emoyeni.
Izilinganiso Ezihlukile Ze-ETOPS Zichaziwe
Izilinganiso ze-ETOPS zinqunywa isikhathi esiphezulu sokuphambukisa indiza esigunyazwe ukundiza ngenjini eyodwa engasebenzi. Okwamanje kunezilinganiso ezine ezijwayelekile ze-ETOPS: ETOPS-120, ETOPS-180, ETOPS-240, kanye ne-ETOPS-330.
Isilinganiso -120 sivumela indiza ukuthi indize imizila eyigcina phakathi nemizuzu engu-120 isikhathi sokundiza (enjinini eyodwa) yesikhumulo sezindiza esiseduze esifanelekile. Ngokufanayo, izilinganiso -180, -240, kanye -330 zivumela izikhathi zokuphambukisa eziphezulu zemizuzu eyi-180, 240, kanye nemizuzu engama-330 ngokulandelana.
Isilinganiso se-ETOPS sendiza asincikile kuphela emandleni endiza. Inkampani yezindiza esebenza endizeni kufanele futhi ihlangabezane nezimfuneko eziqinile zokusebenza nezokulungisa ezihlobene nesilinganiso esifiswayo.
Indlela Izinkampani Zezindiza Ezihlangabezana Ngayo Nezimfuneko ze-ETOPS
Izinkampani zezindiza ezifuna isitifiketi se-ETOPS kufanele zithole inqubo yokugunyaza eqinile ebandakanya kokubili indiza nomsebenzisi. Indiza kufanele ibonise ukwethembeka kwayo ngochungechunge lokuhlola, okuhlanganisa izindiza zesikhathi eside ezinenjini eyodwa engasebenzi.
Inkampani yezindiza kufanele futhi ibonise amandla ayo okuhlangabezana nezidingo zokusebenza nezokulungisa. Lokhu kuhlanganisa ukwenza izinqubo ezinemininingwane zokuhlela nokuthumela indiza, ukuqeqesha abashayeli bezindiza ukuze babambe ukwehluleka kwezinjini nezinye izimo eziphuthumayo, nokusebenzisa uhlelo lokunakekela oluqinisekisa ukuqhubeka nokuhlala kwendiza emoyeni.
Uma isitifiketi se-ETOPS sesinikiwe, inkampani yezindiza kufanele igcine ukuthobelana nezidingo ngokucwaningwa kwamabhuku okuvamile nokuhlolwa yiziphathimandla ezilawulayo.
Umthelela Emizileni Yendiza
I-ETOPS ibe nomthelela omkhulu emizileni yendiza, ivula imizila eqondile nesebenza kahle yonqamula izilwandle nezindawo ezikude. Lokhu kuholele ekutheni kube nezikhathi zokuhamba ezimfishane kanye nezindleko eziphansi zokusebenza kwezinkampani zezindiza.
Ngaphambi kwe-ETOPS, izindiza ezithatha uhambo olude bekufanele zilandele imizila ejikelezayo ukuze zihlale endaweni efinyelelekayo ezikhumulweni zezindiza ezifanele. Ngawo, izindiza zingandiza imizila eqondile, eyaziwa ngokuthi “iyindilinga enkulu,” imizila elandela ukugoba komhlaba futhi ifinyeze ibanga lokundiza.
Nokho, izinzuzo azinazo izinselele. Ukuhlela Ibanga Elandisiwe Izindiza Zezimo Zokusebenza Zenjini Embili zidinga ukucatshangelwa ngokucophelela kwezinto ezifana nokusetshenziswa kukaphethiloli, izimo zezulu, kanye nokuba khona kwezikhumulo zezindiza ezifanele. Lokhu kudinga isofthiwe yokuhlela indiza eyinkimbinkimbi kanye nabathumeli bezindiza abaqeqeshwe kakhulu.
Izimo Zempilo Yangempela Ezibonisa Izinyathelo Zokuphepha ze-ETOPS
Amazinga Okusebenza Okusebenza Kwe-Twin-injini Enwetshiwe afakazela ukuphepha kwayo ngemicimbi yempilo yangempela. Thatha isigameko se-‘Gimli Glider’ ngo-1983: i-Air Canada Boeing 767, ebhekene nephutha likaphethiloli, yaphelelwa uphethiloli phakathi nendiza. Kodwa izisebenzi zandiza ngobuchule zaze zafika endaweni ephephile enkundleni yezindiza endala eGimli, eManitoba.
Bese kuba khona iBritish Airways Flight 9 ngo-1982. I-Boeing 747 yandiza emlotheni wentaba-mlilo, okwenza zonke izinjini zahluleka. Izisebenzi zehla, zavula kabusha izinjini, futhi zehla ngokuphepha eJakarta.
Nakuba zingaxhumene ngokuqondile, lezi zigameko zigcizelela ingqikithi ye-ETOPS: ukuqinisekisa ukuthi izindiza zifika esikhumulweni sezindiza ngokuphepha uma injini yehluleka.
Imithetho Yekusasa
Ikusasa lemithetho ye-ETOPS libukeka lithembisa, ngentuthuko eqhubekayo kubuchwepheshe bezindiza kanye nezinqubo zokusebenza. Njengoba izindiza ezinenjini emibili ziba zithembeke nakakhulu futhi zikwazi ukusebenza, kungenzeka ukuthi izikhathi zokuphambukisa zizokwandiswa ngokuqhubekayo.
Kukhona futhi izingxoxo mayelana nokusebenzisa izimiso ze-Extended-range Twin-engine Operational Performance Standards endizeni enenjini ezintathu nezine, ngokuqaphela ukuthi ukwethembeka kwezinjini akuxhomekile kuphela enanini lezinjini.
Kodwa-ke, umgomo wokugcina uhlala ufana: ukuqinisekisa izinga eliphezulu lokuphepha ekusebenzeni kwezindiza ezinenjini emibili.
Isiphetho
Ububanzi Obunwetshiwe Amazinga Okusebenza Okusebenza kwe-Twin-engine amele ingqopha-mlando ebalulekile ekuthuthukisweni kwendiza yesimanje. Imithetho nemithetho yayo ayivumelanga nje kuphela izindiza ezinenjini ezimbili ukuba indize imizila emide ngendlela ephumelelayo, kodwa futhi ziye zabeka izindinganiso ezintsha zokwethembeka kwendiza, izinqubo zokusebenza, nokuphepha.
Njengoba sibheke esikhathini esizayo, kuyacaca ukuthi le mithetho izoqhubeka nokudlala indima ebalulekile ekulolongeni imboni yezokundiza.
