Indiza yakho iziphatha ngendlela ehlukile ohlotsheni ngalunye lokuphakama okusekelwe kuzici zendawo zendawo, ngakho ukwazi lokhu kuhlukahluka kubaluleka ekusebenzeni okuphephile.
Amaphrothokholi Okuphepha Ahlobene Nokuphakama
Amaphrothokholi okuphepha ezinhlobonhlobo izinhlobo zokuphakama ziyimpilo yokuphepha kwendiza okukuvikela phakathi nazo zonke izigaba zendiza. Lawa maphrothokholi akusiza ukuthi ugcine ukuhlukaniswa okuphephile kwendawo nezinye izindiza.
I-Altitudes Evikelekile Encane Nezinhlobo Zokuphathwa Kwe-Altitude
Ukuphakama okuncane okuphephile okudingeka ukulondoloze kuncike endaweni yakho yokusebenza nokuhlukile izinhlobo zokuphakama izilinganiso. Nazi izimfuneko ezibalulekile:
| Uhlobo Lwendawo | Ukuphakama Okudingekayo | Ibhafa yokuphepha |
|---|---|---|
| Izindawo Eziminyene | 1,000 ft ngaphezu kwesithiyo esiphezulu | 2,000 ft irediyasi evundlile |
| Izindawo ezingaminyene | 500 ft ngaphezu kwendawo | 500 ft ukusuka ezakhiweni |
| Indawo Yezintaba | 2,000 ft ngaphezu kwesithiyo esiphezulu | 3-mile ovundlile imvume |
Ukuphatha okuhlukahlukene izinhlobo zokuphakama idinga ukuthi ugcine ubude obanele bokufika endaweni ephuthumayo ngaphandle kokubeka abantu noma impahla engcupheni.
Izinqubo Zokugwema I-Terrain
Isu lakho lokugwema indawo kufanele lihlanganise okuhlukile izinhlobo zokuphakama izilinganiso ngenkathi usebenzisa amasistimu okuphepha esimanje. I-Terrain Avoidance and Warning System (TAWS) inikeza le misebenzi ebalulekile:
*I-Forward Looking Terrain Avoidance (FLTA)
*Isexwayiso Sokwehla Ngaphambi Kwesikhathi (PDA)
*Izixwayiso Zezinga Elidlulele Lokwehla
*Izixwayiso Zezinga Lokukhuphuka Elibi
Ukuwela ama-Ridge noma ama-mountain pass kudinga izinqubo ezithile zokuhlukile izinhlobo zokuphakama:
| Isimo Somoya | Ukucaciswa Okudingekayo | Sondela i-Angle |
|---|---|---|
| Ngaphansi kwamafindo angama-20 | 1,000 ft ngaphezu kwendawo | 45° ukukhuphuka |
| Ngaphezu kwamafindo angama-20 | 2,000 ft ngaphezu kwendawo | 45° ukukhuphuka |
Amaphrothokholi Okwehla Kwesimo Esiphuthumayo
Izinqubo zokwehla kwezimo eziphuthumayo kufanele zibhekane nezinhlobonhlobo izinhlobo zokuphakama kuyilapho ugcina indiza ngaphansi kolawulo. Landela lezi zinyathelo ngesikhathi sokwehla kwezimo eziphuthumayo:
- Sula indawo futhi unqume lapho umoya uya khona
- Yehlisa i-throttle ukuze ingenzi lutho
- Faka igiya lokubikezela ngaphansi kwe-VLO
- Gcina i-engeli yebhange engu-30-45° ukuze uthole izici zomthwalo omuhle
- Gada isivinini ngaphakathi kwemikhawulo yesakhiwo
Different izinhlobo zokuphakama abaphathi ngesikhathi sezimo eziphuthumayo badinga ukuthi ugxile kulokhu:
-Ukutholwa kwe-Altitude akukho ngaphansi kwamamitha angu-1,500 AGL
-Ukwehla okuphezulu kwamafithi angu-2,000 ngenqubo ngayinye
-Ukuqapha kwethrafikhi okuqhubekayo kusetshenziswa i-ACAS/TCAS
Ukuphatha okuhlukahlukene izinhlobo zokuphakama ngesikhathi sokwehla kwezimo eziphuthumayo kudinga ukuhlanganiswa kwe-ATC nokuqwashisa ngezimo. Setha i-transponder yakho ibe ngu-7700, vula imodi yesimo esiphuthumayo kumpahla ye-ADS/CPDLC, futhi uqinisekise ukuthi ama-altimeters afana nezilungiselelo zendawo ze-QNH noma ze-QFE.
Lawa maphrothokholi okuphepha ehlukene izinhlobo zokuphakama ukusiza ukugcina ukuhlukaniswa kwezindawo okuphephile nokuqinisekisa amamajini okusebenza anele. Ubuchwepheshe bakho kulezi zinqubo kanye nokusebenzisa kahle amasistimu angaphakathi kwakha inethiwekhi yokuphepha enemininingwane yokuphathwa kokuphakama kokuphakama.
Isiphetho
Ukuba nekhono ezinhlotsheni ezahlukene zezilinganiso zokuphakama kokuphakama kuyimpilo yokuphepha kwendiza nokusebenza kahle kakhulu. Ukuqonda kwakho okugcwele kokuhluka kokuphakama kokuphakama kuthinta ukuphepha kwendiza, ukusebenza kwendiza, namakhono akho okwenza izinqumo.
Lo mhlahlandlela ophelele ukufundise:
-Ubudlelwano obubalulekile phakathi kwezinhlobo ezinhlanu zokulinganisa ukuphakama
-Izibalo zokuphakama kwengcindezi nokuminyana
-Ubuchwepheshe bokulinganisa obuthuthukisiwe kanye nezicelo zabo
-Imiphumela yephethini yesimo sezulu ekufundweni kokuphakama
-Izinguquko zesifunda ezidinga ukulungiswa okuthile
-Amaphrothokholi okuphepha aphethe ukuphathwa kokuphakama
Ukundiza kudinga nje ukuqaphela okunembe ngokuphakama ezimeni ezihlukahlukene. Ukwazi ukuhumusha ukufundwa kokuphakama okuhlukile ngenkathi ucabanga ngezinto zemvelo, ukuhlukahluka kwesifunda, nezinqubo zokuphepha kusiza ukuvikela izingozi futhi kuzonikeza ukusebenza okuhle kwendiza.
Lolu lwazi lwezilinganiso zokuphakama kokuphakama lukusiza ukuthi uqondise ezimeni eziyinselele futhi wenze izinqumo zokuhlela indiza unolwazi kuyilapho ugcina izindinganiso eziphakeme zokuphepha phakathi nomsebenzi wakho wokundiza. Qaphela ukuthi ukutolika okunembile kokuphakama kwe-altitude kusebenza njengesivikelo sakho esiyinhloko ngokumelene no-17% wezingozi zendiza ezibangelwa ukungaqondi kahle okuhlobene nokuphakama kwendiza.
