I-Aviation iye yahamba indlela ende ukususela Wright Brothers' Inqwelo-moya yokuqala ngowe-1903. Emva phayaa, abaqhubi beenqwelo-moya babethembele kancinane kwimaphu, ikhampasi nokuzimisela ngokupheleleyo. Ngoxa ezi zixhobo zazisebenza, zazingasoloko zikhuselekile—ingakumbi kwimozulu embi okanye kwiindawo ezingaqhelekanga.
Namhlanje, abaqhubi banamhlanje banenzuzo yokutshintsha umdlalo: i-NAVAIDS (i-Navigational Aids). Ezi nkqubo—ukususela kwiibhakoni ezisekelwe emhlabeni ukuya kuthungelwano lwesathelayithi—zikhokela iinqwelo-moya ngokuchaneka ngokuthe ngqo, ziqinisekisa ukuba iinqwelo-moya zikhuselekile nakwezona meko zinzima.
Kodwa yintoni kanye kanye i-NAVAIDS, kwaye kutheni ibaluleke kakhulu ukuba ibhabha? Kwesi sikhokelo, siza kuphonononga ukubaluleka kwazo, sicazulule ezona ndidi zixhaphakileyo, kwaye sibonise indlela abaluguqule ngayo uphapho.
Ziziphi ii-NAVAIDS kwaye kutheni zibalulekile?
Ukuba igama elithi NAVAIDS livakala lingaqhelekanga, ungakhathazeki-yinto nje ye-aviation shorthand. I-NAVAIDS imele i-Navigational Aids, kwaye ligama le-umbrella leenkqubo ezinceda abaqhubi beenqwelo-moya bafumane indlela yabo esibhakabhakeni.
Ezi zixhobo ziza ngeendlela ezininzi, ukusuka kwiibhakhoni zikanomathotholo ezisekelwe emhlabeni ukuya kuthungelwano lwesathelayithi. Ngokudibeneyo, babonelela ngesikhokelo sokuhamba ngeenqwelomoya ngokukhuselekileyo nangokuchanekileyo, nokuba ukubonakala kunguziro.
Kutheni Uncedo lokuhamba Kubalulekile?
Khawube nomfanekiso wakho uzama ukuqhuba imoto engenazimpawu zendlela, iGPS, nemephu ongakwaziyo ukuyifunda. Kwakunjalo ke ukubhabha ngeentsuku zokuqala zokubhabha. Abaqhubi beenqwelo-moya babexhomekeke kwiimephu, iikhampasi, neempawu zomhlaba—izixhobo ezazisebenza kakuhle kwimozulu epholileyo kodwa zasilela ngokulusizi kumafu, yinkungu, okanye kumhlaba ongenabala onje ngeelwandle neentlango.
I-Navigational Aids yatshintsha yonke into. Bavumela abaqhubi beenqwelo-moya ukuba babhabhe ngaphandle iimbekiselo ezibonakalayo, besebenzisa izixhobo zokulandelela indawo yabo, umphakamo, kunye nesalathiso. Xa usiva ngomqhubi "ohamba ngezixhobo," bathembele kwi-NAVAIDS njenge-VOR, GPS, kunye ne-ILS ukuze bahlale endleleni.
Kodwa i-NAVAIDS ayikho nje into elula-imalunga nokhuseleko. Ngokubonelela ngedatha yexesha langempela, banceda abaqhubi beenqwelo moya baphephe ukungqubana, bahlale becacile indawo yomoya ethintelweyo, kwaye uhambe kwimozulu embi.
Ngamafutshane, i-NAVAIDS sesona sizathu sokuba uhambo lweenqwelo moya lwangoku lukhuselekile kwaye luthembekile. Baye bajika ukubhabha ukusuka kumdlalo wongcakazo oyingozi ukuya kwisayensi echanekileyo-kwaye bangumqolo wayo yonke inqwelomoya oyithathayo.
Iindidi ze-NAVAIDS ezisetyenziswa kwi-Aviation namhlanje
I-NAVAIDS iza ngeendlela ezininzi, nganye ilungiselelwe ukusombulula imingeni ethile kuhambo ngenqwelomoya. Nalu ujongo olusondeleyo kwezona ntlobo zixhaphakileyo kunye nendlela ezisebenza ngayo:
ILS (Inkqubo yokuHlaliswa kwesixhobo)
The Inkqubo yokuFakwa kwesiXhobo ngumhlobo osenyongweni womqhubi wenqwelomoya ngexesha lemozulu embi. Yinkqubo echanekileyo ekhokelela inqwelomoya kumgaqo weenqwelomoya, naxa ukubonakala kukufutshane neqanda.
I-ILS inamacandelo amabini aphambili: i-localizer kunye ne-glide slope. I-localizer iqinisekisa ukuba inqwelomoya ihlala ihambelana nomgaqo weenqwelo-moya, ngelixa i-slope ye-glide ilawula i-angle yokuhla. Bebonke, bavumela abaqhubi beenqwelo-moya ukuba bahlale ngokukhuselekileyo kwiimeko apho umgaqo weenqwelo-moya usithekile ngokupheleleyo.
Nangona kunjalo, i-ILS inoluhlu olulinganiselweyo malunga neekhilomitha ezingama-21, iyenza ibe yinto efanelekileyo kwindlela yokugqibela kodwa kungekhona ukuhamba kwindlela.
I-VOR (Uluhlu lwe-Omnidirectional oluphezulu kakhulu)
Eyona Kakhulu Uluhlu oluPhakamileyo lwe-Omnidirectional yinkqubo esekwe emhlabeni ebiyeyona nto iphambili kuphapho kangangamashumi eminyaka. Isebenza ngokusasaza iimitha zerediyo, okanye iiradials, macala onke.
Abaqhubi beenqwelo moya banokungena kwisikhululo se-VOR kwaye balandele iradial ethile ukuhamba ukusuka kwindawo ukuya kwenye. Ngoluhlu oluya kuthi ga kwi-360 yeemayile ze-nautical, ii-VOR zifanelekile kwiinqwelomoya ezimgama omde.
Ngaphandle kokunyuka kwe-GPS, ii-VORs zihlala ziyi-backup ethembekileyo kwaye zisasetyenziswa ngokubanzi kuzo zombini iinqwelomoya kunye neenqwelomoya jikelele.
I-NDB (Ibhakana eNgekho umkhombandlela)
I-NDB yenye yeyona NAVAIDS indala isasetyenziswa. Ikhupha isignali ye-frequency enye ukuba kwi-ADF (i-Automatic Direction Finding) izixhobo zithatha.
I-ADF isebenza njengekhampasi, inotolo olukhomba kwisikhululo se-NDB. Ngelixa le nkqubo ilula kwaye ithembekile, ayichanekanga kangako kunezinye iindlela zale mihla njengeVOR okanye iGPS.
Ii-NDB zihlala zisetyenziswa njenge-backup okanye kwiindawo ezikude apho ezinye ii-NAVAIDS zingafumanekiyo.
GPS (Global Positioning System)
IGPS likamva lokuhamba ngenqwelomoya. Isebenzisa iisathelayithi kunye ne-triangulation, ibonelela ngedatha yexesha langempela kwisikhundla, ukuphakama, kunye nesantya.
Enye yeenzuzo ezinkulu zeGPS kukufikelela kwayo kwihlabathi jikelele. Ngokungafaniyo neenkqubo ezisekelwe emhlabeni, ayixhomekekanga kwiziseko ezingundoqo zendawo, iyenza ilungele izikhululo zeenqwelo moya ezikude kunye neenqwelomoya ezikude.
I-GPS ikwachaneke ngendlela emangalisayo, ivumela abaqhubi beenqwelo-moya ukuba bajonge uhambo lonke-ukusuka ekundulukeni ukuya ezantsi-besebenzisa imiqondiso yesathelayithi yodwa.
INS
I-INS yinkqubo yokuzimela esebenzisa i-gyroscopes kunye ne-accelerometers ukulandelela indawo yenqwelomoya.
Isebenza ngokulinganisa amandla asebenzayo kwinqwelomoya kunye nokusebenzisa loo datha ukuqikelela indawo yayo. Ngenxa yokuba ayixhomeki kwiimpawu zangaphandle, i-INS ikhuselekile ekuphazamisekeni okanye kwi-jamming.
Nangona kunjalo, ukuba inkqubo iyasilela, abaqhubi beenqwelomoya balahlekelwa yiyo yonke idatha yokuhamba. Ukunciphisa lo mngcipheko, iijethi ezininzi zorhwebo ziphethe iinkqubo ezintathu ze-INS zokungafuneki.
Ukusuka kokuchaneka kwe-ILS ukuya kukufikelela kwihlabathi jikelele kwe-GPS, i-NAVAID nganye idlala indima ebalulekileyo kuphapho lwangoku. Ngokudibeneyo, baqinisekisa ukuba abaqhubi bayakwazi ukuhamba ngokukhuselekileyo nangokufanelekileyo, nokuba iimeko zinjani na.
I-Evolution ye-NAVAIDS: Ukusuka kwiiBeacons ukuya kwiiSathelayithi
I-NAVAIDS ihambe indlela ende ukususela kwiintsuku zokuqala zokuhamba ngeenqwelomoya. Ngeminyaka yee-1920, abaqhubi beenqwelo-moya babexhomekeke kwiibhakana ezibonwayo—izibane ezidanyazayo ezibekwe ecaleni kwendlela yomoya—ukuze bahambe ebusuku. Ngeminyaka yoo-1930, iibhikhoni zikanomathotholo ezifana ne-NDB (i-Non-Directional Beacon) yaba ngumgangatho, inika ukuchaneka okungcono kunye noluhlu.
Kwiminyaka yoo-1940 yabona ukungeniswa kweVOR, eyathi yaguqula indlela yokuhamba ngenqanawa ngeeradials zayo zeomnidirectional. Ngeminyaka yoo-1980, kwavela i-GPS, isebenzisa iisathelayithi ukunika ugutyulo lwehlabathi kunye nokuchaneka okungazange kubonwe ngaphambili.
Namhlanje, ukuqhubela phambili okunje nge-ADS-B esekwe kwindawo kunye ne-GPS eyandisiweyo ityhala imida nangakumbi. Ezi nkqubo zibonelela ngomkhondo wexesha lokwenyani, uhlaziyo lwemozulu, kunye nokuphepha ukungqubana, ukwenza ukubhabha kukhuseleke kwaye kusebenze ngakumbi kunangaphambili.
Ukuqonda olu tshintsho kunceda abaqhubi beenqwelo moya baxabise izixhobo abazisebenzisayo namhlanje-kwaye zibalungiselele izinto ezintsha zangomso.
Iimpazamo eziqhelekileyo xa usebenzisa i-NAVAIDS (Kwaye unokuziphepha njani)
Nabaqhubi abanamava banokwenza iimpazamo xa besebenzisa i-NAVAIDS. Nantsi imigibe eqhelekileyo—kunye nendlela yokuyinqanda:
Ukutolika ngendlela engeyiyo iiRadi zeVOR: Ukubhabha kwisikhululo se-VOR kwahlukile ekubhabha kuyo. Ukubhidanisa ezi zimbini kunokukhokelela kwiimpazamo zokuhamba. Soloko ujonga kabini isihloko sakho kunye neradial.
Ukuthembela ngaphezulu kweGPS: I-GPS ithembeke ngendlela emangalisayo, kodwa ayinakusilela. Ukulahleka komqondiso okanye ugcino-lwazi oluphelelwe lixesha kunokukhokelela kwiimpazamo. Soloko uphethe iitshathi zamaphepha kwaye wazi indlela yokusebenzisa i-NAVAIDS yesintu efana ne-VOR kunye ne-NDB.
Ukungahoywa kwe-ILS Unyino: I-ILS ichanekile, kodwa inoluhlu olulinganiselweyo (malunga neekhilomitha ezingama-21). Ukuthembela kuyo kwangethuba kakhulu okanye emva kwexesha kakhulu kunokuyibeka esichengeni indlela yakho.
Ukungahoywa kwe-NDB Calibration: Ii-NDB ziqhele ukwenza iimpazamo ezifana nediphu kunye nokuphazamiseka. Rhoqo ulungelelanise i-ADF yakho kwaye uhlolisise kunye nezinye i-NAVAIDS.
Ngokuhlala uqaphela ezi mpazamo-kunye nokuziqhelanisa neenkqubo ezifanelekileyo-ungahamba ngokukhuselekileyo nangokuzithemba, kungakhathaliseki ukuba iimeko zinjani.
Ulwazi lwe-NAVAID: Isitshixo sokuPhapha ngokuKhuselekileyo
Ukufundisa i-NAVAIDS kubalulekile kuye nawuphi na umqhubi wenqwelomoya. Inkqubo nganye inamandla kunye nobuthathaka bayo, kwaye ukuqonda ezi nuances kubalulekile kukhuseleko lokubhabha.
Ngokomzekelo, imiqadi ye-ILS inokuchatshazelwa yi-scallop (ukuphazamiseka kwesignali) kunye nokuphazamiseka konxweme (ukuphazamiseka kufuphi nonxweme). Iiradials ze-VOR ziziphatha ngokwahlukileyo ngokuxhomekeke ekubeni ubhabha uye okanye usuka esikhululweni. Ii-NDB ziqhele ukwenza iimpazamo, kwaye iGPS inokunika ufundo olungachanekanga ukuba iwotshi yakho ekwibhodi ayidityaniswanga.
Ezi zintsonkotha zibalaselisa isizathu sokuba uqeqesho olukhethekileyo lubaluleke kangaka. Isikolo esihle sokubhabha asiyi kukufundisa nje ukusebenzisa i-NAVAIDS, kodwa nendlela yokuyicombulula xa izinto zingahambi kakuhle.
I-NAVAIDS intsonkothile, kwaye ukuhamba kuzo ngempumelelo sikhono esingundoqo sokufumana ilayisenisi yakho yokuqhuba iinqwelomoya kunye namanqaku aphezulu. Umqeqeshi onamava unokuphendula imibuzo yakho, acacise amathandabuzo, kwaye akuncede usebenzise ithiyori kwiimeko zehlabathi lokwenyani.
At Florida Flyers Flight Academy, i-NAVAIDS yinxalenye engundoqo yekharityhulam. Abahlohli babo abaziingcali babonelela ngoqeqesho olusebenzayo, beqinisekisa ukuba ukulungele ukusebenzisa ezi nkqubo ngokuzithemba nangokukhuselekileyo.
