VMC ndi IMC ndizomwe amagwiritsa ntchito pofotokoza momwe nyengo ikuyendera. VMC imaimira zochitika za meteorological ndipo IMC imayimira chida cha meteorological . Ngakhale kuti mawu awiriwa amagwiritsidwa ntchito mosiyana (ngakhale, zomvetsa chisoni, pakati pa akatswiri a zamalonda) ndi mawu a VFR ndi IFR, motero, VMC si yofanana ndi VFR, ndipo IMC si yofanana ndi IFR.
Malamulo a VFR ndi IFR
Monga momwe oyendetsa ndege ambiri amadziwira, pali malamulo awiri a kuwuluka ndege iliyonse: VFR ndi IFR.
VFR ikuyimira malamulo oyendetsa ndege, omwe amapanga malamulo omwe woyendetsa ndege amayendetsa ndege pakagwa nyengo nthawi zambiri momveka bwino kuti alole ndegeyo kuwona ndege ikupita. Mwapadera, nyengo imayenera kukhala yabwino kusiyana ndi nyengo yoyenera ya VFR yomwe imaloledwa ku VMC, zochitika zam'madzi zooneka bwino, monga momwe tafotokozera m'malamulo olembedwa ndi olamulira apamwamba othawa. Mawu akuti IFR amaimira malamulo oyendetsa ndege. Nthawi zambiri, nyengo imakhala ngati woyendetsa ndege amasankha VFR kapena IFR
Mmene FAA imafotokozera VMC
Tisanamvetse tanthauzo ndi kufunika kwa VMC, tiyenera kuzindikira kuti pali mitundu iwiri ya VMC. Zolinga zanu, tiyang'ana mkhalidwe wa nyengo komanso osati mlengalenga yomwe imagwirizanitsidwa ndi injini yolephera panthawi ya ndege yothamanga. Izi zikufotokozedwa ndi "V" yayikulu ndi yaing'ono 'mc': Mavms.
Tsatanetsatane wa VMC, malinga ndi Federal Aviation Administration (FAA) ndizochitika za mvula zomwe zimafotokozedwa poonekera, kutalika kwa mtambo, ndi denga lofanana kapena labwino kusiyana ndi minima. Chifukwa FAA ndi ulamuliro wa dziko pankhani yokonza zinthu zonse zokhudzana ndi kayendedwe ka ndege ku US, malamulo ndi malamulo awo adzapitirizabe.
Mawu akuti VMC ndi VFR amagwiritsidwa ntchito mosasinthasintha, ngakhale kuti VMC imatchula nyengo momwemo ndipo VFR imatanthawuza malamulo oyendetsa ndege oyandikana nawo.
Mwachitsanzo, malo owonetseratu a meteorological ayenera kukhala osachepera ofanana ndi zomwe zimafunika kuti malamulo a ndege apite (VFR). Komabe, chifukwa chakuti ndege ikuyendetsedwa mwalamulo pansi pa VFR zinthu zomwe sizikutanthauza kuti woyendetsa ndegeyo adzakhala mu VMC ulendo wonse, monga momwe nkhaniyi ikufotokozera. Kutaya maonekedwe owonetsera (ndi kulowa mu IMC mosadziwika) kungatheke ngakhale pamene mukusunga VFR kuthawa. Komanso, woyendetsa ndege akhoza kuthawa mu VFR zinthu akuuluka pa pulani ya ndege ya IFR, koma zosiyana si zoona: Woyendetsa ndege sangathe kuwuluka mu IFR mikhalidwe pa mapulani a ndege a VFR (osati mwachangu.)
Momwe FAA imafotokozera IMC
Tsatanetsatane wa IMC, malinga ndi FAA, ndizochitika mkhalidwe wa mlengalenga zomwe zimafotokozedwa poonekera, kutalika kwa mitambo, ndi dothi losachepera minima yomwe imatchulidwa kuti ziwoneke bwino (VMC) .
Momwemonso, IMC ndi chikhalidwe cha meteorological chomwe sichingafanane ndi meteorological conditions, kapena nyengo yoipa kuposa VMC.
Zomwe IMC ndi IFR zimagwiritsidwa ntchito mofanana, ngakhale IMC imatchula nyengo yomwe imakhalapo ndipo IFR imatchula malamulo oyendetsa ndege .
Maulendo onse ku IMC ayenera kuyendetsedwa ndi woyendetsa woyendetsa zipangizo komanso pansi pa dongosolo la ndege.
