Chizindikiro chowongolera ndi chimodzi mwa zida zisanu ndi chimodzi zoyendetsa ndege mu ndege. VSI iwuza woyendetsa ndegeyo ngati ndege ikukwera, ikutsika kapena paulendo wothamanga. Chizindikiro chothamanga chimaperekanso chidziwitso pamapazi pa mphindi (fpm) za kukwera kapena kuchoka. Mwachitsanzo, chokwera kapena chokwera chikhoza kukwaniritsidwa mamita 500 pa mphindi, ndipo chizindikiro cha VSI chimapangitsa ntchitoyi kukhala yosavuta.
Ganizirani zawunikiradi yoyenda mofulumira ngati chida cholondola chachindunji ndi bata, makamaka kwa oyendetsa galimoto . Pogwirizana ndi zida zina zisanu (airspeed, indicator attitude, altimeter, kutembenuzira woyang'anira komanso kutsogolera chizindikiro) VSI imapereka woyendetsa ndegeyo chizindikiro chabwino cha ndege.
Momwe VSI Amagwirira Ntchito
Chizindikiro chowongolera chowonekera chimapangidwa ndi chingwe cha mkati mwa chida chowombera. Mzerewu umagwirizana ndi kugwirizana ndi magalasi ku singano pa nkhope ya chida. Mitsempha yotsitsimutsa imagwirizanitsa ndi mkatikati mwa chingwe ndi chombo chogwiritsira ntchito. Mphepete mwazeng'onoting'ono yomwe ili pafupi ndi mliriwu imakhala ndi kuphulika kwa madzi, komwe kumathandizira kuchuluka kwa kukwera kwa mbeu.
Kusintha kwapanikizidwe kumayesedwa pang'onopang'ono mkati mwa chingwecho pamene chikulongosola ndi mgwirizano kuchokera ku chipsinjo. Kuthamanga kwazitsulo pamakina oyandikana ndi zipangizo zozungulira kumatanthauzanso kusintha kwachitsulo, koma kuphulika kumapanga chifuwa chofuna, kuti chidacho chiyese kupanikizika kwapang'onopang'ono kusiyana ndi mkati mwa chingwe.
Izi zimachokera ku zowonongeka zomwe zimapangitsa kuti phokoso likhale lopitirira komanso limakhala lofanana ndi kukwera kwake kapena kumera monga momwe zimayesedwera pa singano yamagetsi pamapazi pamphindi. Pambuyo pa masekondi pang'ono paulendo woyendetsa ndege, zovuta ziwirizo zimakhala zofanana ndipo chizindikiro chowonekera chikuwonekera '0' mapazi pamphindi (fpm).
Zotsatira za kukwera kapena kutsika zimasonyezedwa pazowunikira zowonongeka choyamba monga chidziwitso cha chidziwitso (kutanthauza, kukwera mwadzidzidzi kapena kutsika) ndikuwonetsedwanso ngati chidziwitso cha mlingo (mwachitsanzo, 400 fpm).
Zolakwa ndi Zoperewera
Kuvutitsa : Chizindikiro chowongolera sizolondola panthawi ya chisokonezo komanso pamene mukuyendetsa mwadzidzidzi. Chigoba chophatikizidwa ndi zikopazo ndizokhala masekondi asanu ndi asanu ndi atatu kapena asanu ndi atatu, zomwe zimapangitsa kuti zizindikiro zowonongeka zikhale zopanda phindu pakakhala vuto. Ngati nkhanza zikukumana, woyendetsa ndege ayenera kuyesa kukhala ndi maganizo oyenera pogwiritsa ntchito zizindikiro kapena malingaliro akunja, osati "kuthamangitsa singano" kapena kuyesa kukhalabe wosasunthika.
Static Port Blockage : Ngati sitima ya static imatsekedwa, yofanana ndi altimeter , chizindikiro chowonekera chidzasonyeze '0' ndipo palibe kusintha komwe kudzawonedwe ndi kukwera kapena kubadwa. Komabe, ndege zina zili ndi gwero lina limene limapereka chitsime china cha mlengalenga kwa zida zogwiritsira ntchito poyendetsa polojekiti.
