I-Nautical Mile, njengeyunithi yokulinganisa, yachazwa kuqala njengezinga elijwayelekile emhlabeni wonke eMonaco ngo-1929 kwiNgqungquthela Yomhlaba Yomhlaba Yomhlaba Oyingqayizivele Oyingqayizivele. Ngaphambi kwalokho, kwakungazange kube khona imigomo yomhlaba wonke yokulinganisa amabanga noma lapho ehamba emanzini noma, noma ebaluleke kakhulu, phezu kwamanzi.
I-United States ayizange ithathe i-Nautical Mile njengesilinganiso sayo ejwayelekile ngo-1929 kodwa yadlulela ebhodini ngo-1954 futhi yaqaphela lesi simiso esasetshenziswa emhlabeni wonke.
(I-mile ye-nautical, ngokuyisisekelo esekelwe emkhakheni wezwe, ilingana nomzuzu owodwa we-latitude futhi incane kakhulu kune-mile yesimiso esilinganiselwe umhlaba.)
Ama-Nautical Miles Versus Miles Statute
Emhlabeni wezindiza, indlela ejwayelekile yokulinganisa ibanga yi-mile ye-nautical. Kodwa-ke, igama elijwayelekile livula umnyango wokuphambuka kusuka kwendabuko. Okuhlukile kokusebenzisa i-mile yesimiso (SM) ngokumelene nezimayini ze-nautical (NM) ngokuqondene nezidingo zokubonakala kwe-VFR, okuzo zonke abahamba ngezindiza abazibheka ezingeni eliphansi lesimo sezulu se-VFR (14 CFR 91.155) esicacile ngezinhlobo ezahlukene indawo ye-air and altitudes.
Futhi, ngaphandle kokuthi uqale nje, uyazi igama elithi VFR elimelela iMigomo Yezindiza Zezindiza. I-VFR yesimo sezulu esincane sibhekene nomqondo wokudinga ukubonakala okukhulu (nokuhamba okuningi kusuka emafwini) lapho kuhamba ngenhla ngaphezu kwe-10,000MSL (noma, "izinga lokusolwandle olwandle," elichaza ukuphakama kwezindiza) ngoba abashayeli bezindiza badinga isikhathi esengeziwe sokubona (futhi bagweme) izindiza ezingangena ngaphakathi nasemafwini.
Ukususwa Kwamafu Ngenye Isici
Okunye okungafani nomthetho wokuthi i-mile ye-nautical yinkinga ye-iron-clad universal isilinganiso kanye nesilinganiso ngokuphathelene nesimo sefu, esibuye sisebenzise amakhilomitha omthetho (SM) kunokuba sibe ngamamitha ama-nautical (NM). Kudingeka isidingo sokucacisa ifu ngokucacile ngoba kunzima ukwazi ukuthi leso senzakalo esivela emnyango wesango sihambisana nezimo zemvelo, noma, uma isimo esivela kusikrini somphequluli sihamba, ngaleyo ndaba.
Noma kunjalo, nansi izincazelo zomama wama-nautical namasimende, kanye nokuguqulwa okulula okulula.
Ukulinganisa okulinganiselwe
Isitatimende Mile:
- 1 SM = amamitha angu-1,609
- 1 SM = 5,280 amamitha
- I-1SM = .869 i-NM
I-Nautical Mile:
I-mile eyodwa yama-nautical (NM) njengoba kuchaziwe yi-NOAA njenge: "Iyunithi ebanga elisetshenziselwa ukuhamba olwandle kanye nokubikezela olwandle. Ilingana namamitha angu-1.15 omthetho noma amamitha angu-1,852. Futhi ubude beminithi engu-1 ye-latitude. "
- 1 NM = 1,852 amamitha
- 1NM = 6,076 amamitha
- 1NM = 1.151 amamitha omthetho
Emhlabeni wezindiza , ibanga ngokuvamile lilinganiselwa emakhilomitha e-nautical, ngaphandle kokubonakala, okuvame ukushiwo noma okubikezelwe kumama omthetho.
Izinga lokusheshisa
Lapho uhlola amamayela e-nautical kufanelekile ukuphawula umehluko ngamazwi asetshenziswe kaningi njenge-MPH nama-knots.
- I-MPH: Ngamayela omthetho, izilinganiso zejubane zinikezwa ngamamayela ngehora, kufana nezinqola.
- I-Knot : Isilinganiso esisheshayo esivumelwaneni sezindiza yilona i-knot. Iphuzu elilodwa lilingana nemitha eyodwa ye-nautical ngehora. Izinkomba ezindiza ezindizeni zilinganiswa ngamafindo.
