Njira yokhala ndi malo okhala ndi njira zowonongeka (LPV) ndi njira yamakono yamakono yopangira ndege yomwe imagwiritsa ntchito njira yowonjezera yowonjezereka (WAAS) ndi mphamvu zenizeni za GPS kuti zitha kufika pa ndege. LPV imapereka malo olondola kwambiri apamwamba okwera ndege. Njira ya LPV ikhoza kuyendetsa woyendetsa ndege kumtunda wokha wa masentimita 200 kapena 250. Phindu ndilo kuti izi zimapangitsa ndege kuti zifike pamtunda poonekera kwambiri.
Pokhapokha ngati muli ndi mphamvu (ie, osakhoza kuyenda LPV njira) zosaoneka bwino zosaoneka bwino pa bwalo la ndege zingakakamize woyendetsa ndege kuti apite ku ndege ina yosayenera.
Kawirikawiri, LPV ikuyandikira, ndi ndege zogwira WAAS, kutsegula zatsopano (zosapezekepo kale) zosankha za oyendetsa ndege. Ndi ndege zowonongeka bwino, othawa ndege amatha kusunga nthawi, ndi ndalama, pogwiritsira ntchito WAAS chifukwa ndi chithandizo chapadera kwambiri choyenda panyanja . Kuphatikiza apo, oyendetsa ndege okonza LPV amatha kukwanitsa kumtunda kumalo okwera ndege omwe sakanatha kupita, monga maulendo akuthamanga. Amathanso kupanga njira zomwe sizikuthandizidwa mosavuta ndi maulendo a pawailesi, nyengo yomwe ili yoipitsitsa kuposa momwe amazoloŵera. M'malo modalira paulendo woyenda paulesi, oyendetsa ndege angadalire dongosolo lachangu lomwe likuyenda bwino kwambiri. Ndilolondola kolingana ndi kayendetsedwe kameneka komwe kumapangitsa oyendetsa ndege kuti apite kumtunda (popanda maonekedwe owonetsera) kapena pamene akuuluka m'mitambo.
Momwe LPV imagwirira ntchito
Njira ya LPV ndi yofanana ndi njira ya LNAV / VNAV, koma ili yeniyeni ndipo ingalole kuti mbeu ifike pamtunda wa mamita 200 mpaka 250. UTHENGA wa WAAS umafunika kuti ukhale wowongoka ndi wowongoka, ndikuwukhazikitsa njira yoyenera. Komabe, njira ya LNAV / VNAV ndi yosadziwika bwino.
Ndipotu, njira ya LPV ndi yofanana ndi kayendedwe ka zipangizo (ILS) koma ndi yolondola chifukwa imagwiritsa ntchito zamakono zamakono. Ndiponso, palibe zipangizo zamtengo wapatali zomwe zimakhala zofunikira zomwe zikutanthauza kuti pali nthawi yochepetsera komanso zochepa. Izi zikutanthawuza kuti mtengo wake ndi wotsika chifukwa palibe zipangizo komanso osasamalira nthawi zonse.
Momwe WAAS Ntchito
WAAS imachotsa zolakwika kuchokera ku zizindikiro za GPS pofufuza ndondomeko ya GPS pa siteshoni yapamwamba ndikutumizira uthenga wolandirira GPS kuti alandireni. Ovomerezekawo, amatha kuchotsa zolakwika zilizonse za GPS. Kuchita izi kumapangitsa kuti GPS izidziwitse zolakwika zowonjezera ndipo zimapereka zotsatira zomveka bwino.
Chifukwa chiyani WAAS ndi bwino
Kulondola kwa GPS kuli bwino kuchokera pamtunda wa mamita 100 ndi utumiki wamba wa GPS kufika pafupi mamita asanu ndi awiri ndi WAAS. Izi sizikusoweka malo alionse olakwika ndipo zimapereka chithunzithunzi cholondola kwambiri chothandizira.
Mapindu a WAAS kupita kudziko lonse lapansi ndi aakulu. Mapinduwa akuphatikizapo kuchuluka kwa mphamvu, kukhala ndi mphamvu zogwiritsira ntchito njira zowonongeka, kuchepetsa zipangizo zamagetsi (ponseponse ndi pansi), ndipo, komaliza, ndikuwonjezereka kufika pamtundu uliwonse wa ndege.
