Isingeniso
Isimo somoya sibambe indawo yakho kokubili ukwesaba nokukhathazeka phakathi kwamabhanoyi kusukela ngaleso sikhathi abazalwane bakwaWright waqala waya esibhakabhakeni. Njengamandla emvelo, alibikezeleki njengoba likhona yonke indawo, lithinta zonke izici zohambo lwendiza ukusuka ekusukeni kwayo kuye lapho ifika khona. Ukuyiqonda akuyona nje into yokufunda yabashayeli bezindiza; kuyisici esibalulekile sesethi yabo yamakhono, edingekayo ukuze kuqinisekiswe ukuphepha nokusebenza kahle kokusebenza kwendiza.
La mandla emvelo, ukuhamba komoya usuka ezindaweni ezinomfutho ophezulu uye ezindaweni ezinomfutho ophansi. Nakuba kubonakala kulula, lesi sici sesimo sezulu sithonya amaphethini wesimo sezulu futhi, ngokwandisa, ukuhamba kwezindiza. Ukuziphatha kungaba mnene futhi kubikezelwe noma kuguquke futhi kube yingozi. Ngakho-ke, abashayeli bezindiza kufanele bathole ulwazi olujulile lwe-dynamics yayo ukuze bahambe esibhakabhakeni ngempumelelo.
Kulabo abangaphandle kwendiza, ukubaluleka kungase kungabonakali ngokushesha. Nokho, ibekela inselele futhi inike amandla abashayeli bezindiza ngokulinganayo. Isandla esingabonakali esingaqondisa indiza ngokuphumelelayo lapho iya khona noma sibeke isithiyo esikhulu esivivinya uchwepheshe bomshayeli wendiza. Inkulumo eqhubekayo mayelana nala mandla emvelo kanye nendima yawo kwezokundiza inamandla njengoba ibalulekile.
Ukuqonda Okuyisisekelo
Ngaphambi kokuhlolisisa imininingwane yokuthi umoya uhlangana kanjani nokundiza, umuntu kufanele aqale abambe izisekelo zalesi simo somkhathi. La mandla emvelo akhiqizwa ukushisa okungalingani kobuso bomhlaba yilanga, okudala izindawo ezinomfutho womoya ohlukahlukene. Uma umehluko omkhulu ekucindezelweni phakathi kwezindawo ezimbili, unamandla umoya okhiqizwayo njengoba umoya ugeleza usuka endaweni enengcindezi ephezulu uye endaweni enengcindezi ephansi.
Umphumela we-Coriolis, umphumela wokuzungeza komhlaba, nawo udlala indima ebalulekile ekuqondeni kwawo kanye nesivinini. Lo mphumela uyibangela ukuthi ishintshe indlela iye kwesokudla eNyakatho Nenkabazwe futhi iye kwesokunxele ENingizimu Nenkabazwe, idale amaphethini ahlukahlukene atholakala emhlabeni jikelele. Ngaphezu kwalokho, izici zezwe njengezintaba, izigodi, nemithombo yamanzi zingathonya ukuziphatha kwayo kwendawo, kwengeze ubunkimbinkimbi obungeziwe ekubaleni kwayo okuhlobene.
Ezingeni eliyisisekelo, kukalwa ngokwejubane nendawo eya kuyo. Lezi zibaluli ezimbili zibalulekile ekuqondeni umthelela ongaba khona ekusebenzeni kwendiza. Isivinini somoya ngokuvamile sivezwa ngamafindo (amamayela e-nautical ngehora) endizeni, kuyilapho ukuqondiswa kwawo kunikezwa ngamadigri ahlobene nenyakatho yeqiniso. Ukuqonda okuphelele kwalezi zimfanelo kubalulekile kubashayeli bezindiza okufanele bahumushe futhi balungise izimo ezishintshayo.
Imithelela Endizeni Yendiza: Umbono Womshayeli
Uma ubuka umshayeli wendiza, la mandla emvelo ahlala esibhakabhakeni, angasiza futhi abekele inselele inqubo yokundiza. Ukuvunguza kwemimoya kungandisa isikhathi nophethiloli odingekayo ukuze ufinyelele indawo oya kuyo. Ngokuphambene, ama-tailwinds, ageleza ohlangothini olufanayo nendiza, anganikeza ukuthuthukiswa okuwusizo, ukunciphisa ukusetshenziswa kukaphethiloli nesikhathi sokuhamba.
Ama-Crosswinds aletha inselele eyingqayizivele, ikakhulukazi phakathi nokusuka nokufika. Lokhu kushaywa kuncike endleleni yendiza futhi kungabangela indiza ukuthi isuke endleleni uma ingaphathwa kahle. Abashayeli bezindiza kufanele basebenzise amasu akhethekile ukuze banxephezele imiphumela ye-crosswind, baqinisekise ukuthi indiza ihlala ihambisana nomzila wezindiza noma indlela yendiza ehlosiwe.
Ukugunda umoya kungenye into ebalulekile kubashayeli bezindiza. Lesi simo sibandakanya izinguquko ezingazelelwe esivinini kanye/noma isiqondiso saso ngebanga elifushane, okungenzeka kokubili sivundlile noma siqondile. Lokhu kungaba yingozi ikakhulukazi phakathi nezigaba ezibucayi zendiza, njengokusuka nokuhlalisa, futhi kudinga ukusingatha okusheshayo nokukhaliphile komshayeli wendiza ukuze alondoloze ukulawula indiza.
Okucatshangelwayo Okubalulekile Kubashayeli Bezindiza
Lapho belungiselela indiza, abashayeli bezindiza kumelwe bacabangele izinto ezimbalwa ezibalulekile mayelana nalo. Okokuqala nokubaluleke kakhulu, isithangami sangaphambi kokundiza sihlanganisa ukubukezwa okuphelele kwezimo zamanje nezibikezelo endleleni ehleliwe kanye nasezikhumulweni zezindiza lapho kuzosuka khona nalapho kuyiwa khona. Lolu lwazi lulolonga izinqumo eziningi zomshayeli wendiza, kusukela ekuthuthukisweni kwendlela yendiza kuya ekubalweni komthwalo kaphethiloli.
Okunye okucatshangelwayo ukulinganiselwa kwendiza. Izindiza ezihlukene zinezingxenye ezihlukene zokunqamula umoya, ezisho isivinini esikhulu sokuwela umoya ezingakwazi ukusiphatha ngokuphepha phakathi nokusuka nokufika. Abashayeli bezindiza kumelwe bazi kahle le mingcele ukuze bagweme ukusebenzisa indiza ngaphansi kwezimo ezidlula amandla ayo.
engamamitha futhi idlala indima ekucabangeni kwayo. Ngokuvamile, la mandla emvelo anamandla futhi ahambisana kakhulu ezindaweni eziphakeme, okungaba wusizo ekusebenzeni kahle kohambo lomkhumbi. Nokho, omawala okubangelwa yila mandla emvelo kungenzeka kunoma yikuphi ukuphakama, futhi abashayeli bezindiza kufanele balungele ukuphatha ukunethezeka nokuphepha kwabagibeli nabasebenzi ezimweni ezinjalo.
Umthelela Wezinhlobo Ezihlukene Zomoya endizeni
Umthelela wezinhlobo ezahlukene zendiza ungahluka kakhulu, futhi abashayeli bezindiza kufanele bahlonyiselwe ukuphatha isimo ngasinye. Izinhlobo zohwebo, isibonelo, imimoya engashintshi engase ivune izindiza emizileni ethile, okungenzeka yehlise isikhathi sendiza. I-Jet streams, ngakolunye uhlangothi, iyindilinga emincane yemimoya enamandla ephezulu emkhathini engafinyelela isivinini esingaphezu kwamafindo angu-200. Ukundiza ngejethi kungathuthukisa kakhulu ukusebenza kahle, kodwa ukundiza ngokumelene nakho kungaba yisithiyo esibalulekile.
Amagagasi entaba, abangelwa umoya ogeleza phezu kwezintaba, angase abangele isiyaluyalu esikhulu nokwehla, okubeke engcupheni ukuphepha nokunethezeka kwezindiza. Abashayeli bezindiza kufanele baqeqeshwe ukuze babone izimpawu zezimo zamagagasi asezintabeni futhi bazi indlela yokuhamba noma ukuyizungezile.
Izinhlobo ezishisayo, ezikhiqizwe umehluko wokushisisa kwendawo, zingadala izimo eziyinselele kubashayeli bezindiza, ikakhulukazi phakathi nezigaba zokufika nezokuhlalisa indiza. Lokhu kungaholela ekuthuthukisweni okungalindelekile kanye nokwehla, okwenza kube semqoka ukuthi abashayeli bezindiza baqaphe futhi baphendule ukuze kugcinwe indlela ezinzile.
Indlela Abashayeli Bezindiza Abahamba Ngayo Izimo Ezinomoya
Ukuzulazula ezimweni ezinomoya kuwubufakazi bekhono nokuqeqeshwa komshayeli wendiza. Abashayeli bezindiza basebenzisa amasu ahlukahlukene ukuze balwe nemiphumela yala mandla emvelo. Ngokwesibonelo, lapho bebhekene nezivunguvungu lapho befika, abashayeli bezindiza bangase basebenzise indlela “yenkalankala,” bajikise indiza emoyeni ukuze bagcine indlela eqondile yokundiza ibheke emgwaqeni wezindiza. Njengoba besondela ku-touchdown, abashayeli bezindiza benza indlela “ye-de-crab” ukuze baqondanise indiza nomugqa omaphakathi wendiza.
Endabeni yomoya ovunguzayo kanye nama-tailwinds, abashayeli bezindiza balungisa isivinini sabo somoya ukuze balondoloze isivinini esifanelekile somhlaba, baqinisekise ukuthi abafika ngesikhathi futhi bagcina ukuhlukana okuphephile kwezinye izindiza. Isofthiwe yokuhlela indiza iphinde isize abashayeli bezindiza ukuthi bakhethe imizila esebenzisa ngokunenzuzo umoya ovuzayo, ngaleyo ndlela yonga uphethiloli futhi yehlise ukukhishwa kwekhabhoni.
Uma usebenzisana ne-wind-shear, abashayeli bezindiza bathembele ekuqeqeshweni nasekuziphenduleni okusheshayo. Kumelwe balungele ukukhulisa amandla enjini futhi balungise ukuphakama kwendiza ukuze bamelane nokulahlekelwa noma ukuzuza okungazelelwe kwesivinini somoya okubangelwa ukugunda komoya. Izindiza zanamuhla zivame ukuhlonyiswa ngemishini yokubona ukugunda umoya ezinikeza izixwayiso kusenesikhathi, ezinikeza abashayeli isikhathi esiyigugu sokusabela.
Amathuluzi Namasu Okubikezela
Ngenhlanhla, abashayeli bezindiza abashiywa ukuba babhekane nezinselele zomoya bodwa. Uhlu lwamathuluzi namasu ayatholakala ukuze abikezele izimo zomoya kanye nomhlahlandlela wokuthatha izinqumo. I-radar yesimo sezulu, izithombe zesathelayithi, neziteshi zesimo sezulu ezisekelwe phansi zinikeza idatha yesikhathi sangempela kuyo nezinye izici zesimo sezulu. Abashayeli bezindiza nabo banokufinyelela Izibikezelo ze-Terminal Aerodrome (TAFs) kanye Namashadi Esimo Sezulu Abalulekile (SIGWX), anikeza izibikezelo ngezimo zomoya ezikhumulweni zezindiza ezithile kanye nasemizileni yendiza.
Amasistimu okuhlela indiza ekhompuyutha ahlanganisa le datha yesimo sezulu ukuze iphakamise izindlela ezilungile zendiza, kucatshangelwa isivinini somoya nezikhombisi-ndlela ezindaweni eziphakeme ezihlukene. Abashayeli bezindiza bangasebenzisa lolu lwazi ukuze bahlele imizila egwema umoya omubi noma basebenzise ama-tailwinds.
Elinye ithuluzi elibalulekile kunqolobane yomshayeli wendiza Umbiko Womshayeli (i-PIREP), oqukethe ama-akhawunti mathupha avela kwabanye abashayeli bezindiza mayelana nezimo zezulu abahlangabezane nazo. Le mibiko ingabaluleka kakhulu ekuqondeni ukuziphatha kwesikhathi sangempela kwala mandla emvelo kanye nomthelela wawo ekusebenzeni kwendiza.
Iqhaza Ekusukeni nasekufikeni
Ukusuka kanye nokuhlalisa yizigaba ezibucayi kakhulu zendiza, futhi umoya udlala indima ebalulekile kukho kokubili. Ngesikhathi sokusuka, abashayeli bezindiza kudingeka bacabangele ingxenye yomoya ovunguzayo ukuze abale ubude bendlela yezindiza edingekayo ukuze bathole umphezulu ophephile. Isivunguvungu esinamandla singanciphisa ibanga lokusuka, kuyilapho isivunguvungu somsila singalinyusa kakhulu. Ukunemba nokunaka imininingwane kubalulekile kulezi zibalo ukuze kuqinisekiswe ukuthi indiza inesikhala esanele sokuhamba emoyeni.
Ukufika kuveza isethi yayo yezinselelo. Abashayeli bezindiza kufanele bahlole izimo zabo ukuze bathole umzila wezindiza ofaneleka kakhulu wokufika, kucatshangelwa izici ezifana nesivinini sawo, isiqondiso, kanye nokuba khona kwemimoya ewela imimoya. Indlela yokusondela ingase idinge ukulungiswa ukuze ihambisane nokukhukhuleka komoya, futhi ukuphathwa kwesivinini somoya kuba semqoka kakhulu ekuthinteni okubushelelezi nokuphephile.
Ukufika kwe-Crosswind kudinga izinga eliphezulu lekhono lokushayela indiza, njengoba kufanele kugcine ukuqondisa okuqondisayo kuyilapho kubhekene nokushaywa umoya okungase kube khona. Amasu afana nokuqondisa “kwenkalankala” kanye “nenkalankala” eshiwo ngenhla abalulekile ukuze indiza iqondaniswe nomzila wezindiza kanye nokufinyelela endaweni ephephile.
Inselele kanye nethuba labashayeli bezindiza
La mandla emvelo ayinselelo ekhona yonke indawo endizeni, efuna ukuqapha njalo nokuzivumelanisa nezimo kubashayeli bezindiza. Kodwa-ke, iphinde inikeze amathuba kulabo abawaqondayo ama-nuances ayo. Abashayeli bezindiza abakwazi ukuzulazula ezindaweni ezinomoya bangathuthukisa ukusebenza kwendiza, banciphise ukusetshenziswa kukaphethiloli, futhi baqinisekise ukunethezeka kwabagibeli.
Ngaphezu kwalokho, umthelela womoya endizeni awukho nje kuphela endaweni yokusebenza kwendiza. Ithonya idizayini yesikhumulo sezindiza, okuhlanganisa umumo wendlela yezindiza, ngokuvamile eqondaniswe ukuze ivumelane nendawo yomoya ekhona ukuze usuke kanye nezimo zokufika phansi. La mandla emvelo aphinde abambe iqhaza ekuthuthukisweni kobuchwepheshe obusha bezindiza, njengamasistimu okuhambisa umoya ahlose ukusebenzisa amandla awo ukunciphisa ukuncika kukaphethiloli.
Ezandleni zomshayeli wendiza onekhono, umoya uyayeka ukuba yinselele nje; iba umngane onamandla. Ubungcweti bamakhono ahlobene nomoya kuwuphawu oluhlukanisayo lwabashayeli bezindiza abangochwepheshe, okunikela ekuphepheni kukonke nokusebenza kahle kwemboni yezokundiza.
Isiphetho
La mandla emvelo angamandla ayisisekelo akha isipiliyoni sokundiza. Kusukela ngesikhathi indiza isuka phansi iphinde ibuye, umoya uyisici okumelwe sihlonishwe futhi siqondwe. Abashayeli bezindiza bachitha amahora amaningi befunda ngokuziphatha kwayo, befunda amasu okubhekana nokuhlukahluka kwayo, nokusebenzisa amandla ayo ukuze bazuze.
Uhambo lokudabula endaweni eguquguqukayo yala mandla emvelo lungolokufunda njalo nokuzivumelanisa nezimo. Njengoba ubuchwepheshe buthuthuka kanye nokuqonda kwethu izenzakalo zesimo sezulu kujula, umphakathi wezindiza uyaqhubeka nokuthuthukisa izindlela eziyinkimbinkimbi zokubikezela, ukuzulazula, nokusebenzisa. Yilokhu kuzibophezela okungaguquki ekusebenzeni kahle okuqinisekisa ukuthi isibhakabhaka sihlala siyindawo yokuphepha nethuba.
Kubashayeli bezindiza, akusona nje isithiyo; kuyisikhumbuzo esihlala sikhona sekhono nokunemba okudingekayo ukuze kunqobe isibhakabhaka. Ngokundiza ngakunye, bakhombisa amandla abo okusebenzisa amandla, bawaguqule enseleleni yesimo sezulu abe yimpahla ebalulekile kubuciko bokundiza.
