Indima Yabamukeli be-VOR Ezindizeni
Isamukeli se-VOR sendiza sichaza izimpawu futhi sibonise ulwazi lokuzulazula kumathuluzi anjengalawa:
- Isikhombisi se-VOR (i-CDI - Isikhombisi Sokuphambuka Kwenkambo) – Kubonisa ukuthi indiza isendleleni noma idinga ukulungiswa.
- I-HSI (Isikhombi Sesimo Esivundlile) - Inikeza ukuboniswa okunembile kwendawo yendiza kanye nendlela eya kuyo uma kuqhathaniswa nesiteshi se-VOR.
Incazelo Yama-Radial nama-Bearings
- Ama-radial – Imigqa engokomfanekiso ephuma esiteshini se-VOR, enezinombolo ezisukela ku-001° kuya ku-360° ngokusekelwe ku- enyakatho yamagnetic.
- amabombo – Indlela indiza endiza ngayo uma iqhathaniswa nesiteshi.
- Uma umshayeli wendiza endiza esuka ku-VOR nge-radial engu-090°, indiza isendleleni eya empumalanga isuka esiteshini.
Ukwazi kahle ama-radial nama-bearings e-VOR kubalulekile ekusebenziseni uhlelo lokuzulazula, ukuqinisekisa ukulandelela okunembile kwenkambo kanye nokuqwashisa ngezindawo.
Izinhlobo zeziteshi ze-VOR
Akuwona wonke Iziteshi ze-VOR zifeza injongo efanayo. Zihlukaniswe ngezigaba ngokusekelwe endaweni kanye nomsebenzi, okusiza abashayeli bezindiza ukuba bahambe ezigabeni ezahlukene zendiza.
A I-Terminal VOR (TVOR) isetshenziswa kakhulu ekuzulazuleni ibanga elifushane eduze kwezikhumulo zezindiza. Ihlinzeka ngokumbozwa okungafika kumamayela angama-25 olwandle (i-NM) futhi isetshenziswa kakhulu ezindleleni nasezindaweni zokuhamba kunokuzulazula endleleni.
A I-VOR Yokuphakama Okuphansi (LVOR) isekela izinqubo zokuzulazula zesifunda kanye nezindlela zokusondela, inikeza ukumbozwa okungu-40-50 NM ezindaweni eziphakeme eziphansi. Lawa ma-VOR asiza abashayeli bezindiza ukuthi bahambe emigwaqweni yezindiza iVictor futhi avame ukusetshenziswa endaweni yomoya elawulwayo engaphansi kwamamitha angu-18,000.
A I-VOR Ephakeme (i-HVOR) iklanyelwe ukuzulazula ebangeni elide emgwaqweni futhi inikeza ukumbozwa okufika ku-130 NM ezindaweni eziphakeme. Lawa ma-VOR abalulekile emizileni yezindiza kanye nezindiza ezihamba phakathi kwamazwekazi, eqinisekisa izindlela zomoya ezihlelekile zokuhamba phakathi kwezwe kanye namazwe ngamazwe.
Ukuqonda uhlobo lwe-VOR olusetshenziswayo kubalulekile, njengoba ukumbozwa kuyahlukahluka kuye ngokuphakama, futhi ukuphazamiseka kwendawo kungathinta ukwamukelwa kwesignali.
Indlela Yokufunda Nokuhumusha Inkomba Ye-VOR
Isikhombisi se-VOR sisiza abashayeli bezindiza ukunquma indawo yabo uma kuqhathaniswa nesiteshi se-VOR nokulandelela i-radial ekhethiwe. Ukuqonda izingxenye zayo kuyisihluthulelo sokuzulazula okuphumelelayo.
The Isikhethi Se-Omni-Bearing (OBS) ivumela abashayeli bezindiza ukuthi bakhethe i-radial ethile eya noma evela esiteshini se-VOR. Ngokujikelezisa inkinobho ye-OBS, uhlelo luhambisana nendlela efiselekayo, luqondise indiza iye esiteshini noma isuke kuso.
The Inkomba yokuchezuka kwesifundo (CDI) ikhombisa ukuthi indiza isendleleni yini. Uma inaliti ye-CDI iphakathi nendawo, indiza indiza eceleni kwe-radial ekhethiwe. Uma iphambuka kwesobunxele noma kwesokudla, kudingeka ukulungiswa kwendlela ukuze kuphinde kulungiswe ukuhambisana nomzila ohlosiwe.
Isikhombisi Sokuya/Ukusuka sinikeza isiqondiso maqondana nesiteshi. Uma isibonisi sibonakala "KUYA", indiza iya e-VOR. Uma ikhombisa “KUSUKA”, indiza iyandiza isuka kuyo. Uma idlula ngqo esiteshini se-VOR, inkomba izoshintshashintsha okwesikhashana, iqinisekise ukudlula esiteshini.
Ngokuchaza la mathuluzi ngendlela efanele, abashayeli bezindiza bangahamba ngendlela enembile emigwaqweni yomoya, benze izinguquko eziqondile endleleni, futhi bathuthukise ukuqwashisa ngesimo ngesikhathi sokundiza.
Umhlahlandlela Wesinyathelo Ngesinyathelo Wokuzulazula Usebenzisa i-VOR
Ukuhamba nge- vor kudinga ukulandela inqubo ehlelekile ukuqinisekisa ukunemba nokugcina indlela efanele.
Isinyathelo sokuqala ukulalela imvamisa ye-VOR efanele usebenzisa umsakazo wokuzulazula wendiza. Isiteshi ngasinye se-VOR sisebenza ngemvamisa ye-VHF ehlukile, engatholakala kumashadi ezindiza noma kumathuluzi okuhlela indiza.
Ngemva kokulungisa, isinyathelo esilandelayo ukuhlonza isiteshi usebenzisa isihlonzi sekhodi ye-Morse.
