Iyo Nautical Mile, seyunoyera yekuyera, yakatanga kutsanangurwa seyo mutemo wepasi pose muMonaco muna 1929 paIndaneti Yenyika Yose Inoshamisa Extra Hydrographic Conference. Zvisati zvadaro, kwakanga kusina mutemo wepasi rose wekuyera marefu kana paaifamba mumvura kana, kana zvakakosha, pamusoro pemvura.
IUnited States haina kutora Nautical Mile sezvayakanga yakatarwa muna 1929 asi yakasvetuka mubhodhi muna 1954 uye inoziva izvi zvese-zvakashandiswa zvakashandiswa.
(Nzira yeautical, inonzwisisika kubva kune imwe nzvimbo yepasi, inokwana neminiti imwe yekuyera uye inenge yakareba kwenguva yakareba kupfuura chirevo chemirairo iyo inoyera nyika.)
Nautical Miles Versus Statute Miles
Munyika yenharaunda, nzira yakananga yekuyera kure kuresa maire neutical. Kunyange zvakadaro, shoko rinowanzozarura musuo wekutsauka kubva pane zvisizvo. Imwe nzira iyo inoshandisa mutemo mile (SM) kusiyana neyeutical mile (NM) maererano neVFR kuzivikanwa zvinodiwa, izvo varairi vese vanoziva vanotaura nezvezvinokosha VFR mumamiriro ekunze (14 CFR 91.155) iyo yakananga kune marudzi akasiyana nzvimbo yepamhepo uye yakakwirira.
Uye, kunze kwekuti iwe uchangotanga, iwe unoziva izwi rokuti VFR rinomiririra Visual Flight Rules. VFR yemamiriro emamiriro ekunze anonyangadza kusvika kune chinangwa chekuda kuonekwa kwakanyanya (uye kupfuura kure nemakore) paanenge achibhururuka kupfuura 10,000MSL (kana, "kureva gungwa remazinga," iyo inoderedza kukwira kwegungwa) nekuti vatyairi venguva dzinoda nguva yakawanda yekuona (uye kudzivisa) ndege inogona kupindira uye inobva mumakore.
Cloud Clearance Ndicho Chimwe Chinhu
Chimwe chinhu kunze kwekutonga kuti makiromita emvura ndeye-iron-akavharidza pasi rose uye inoyera pamusoro pokusununguka kwegore, iyo inoshandisawo mairaira emitemo (SM) pane kunyanisa makiromita (NM). Ichokwadi kuti gore rinofanira kuregererwa zvakadii zvakakosha nokuti zvakaoma kuziva kana icho chiitiko chinobva kunze kwemukova we hanger chichitarisana nechokwadi chechokwadi meteorological, kana, kana chiitiko chiri kunze kwehwindo remufambisi wengoroiri chichikwidziridza, nokuda kwechinhu ichocho.
Kunyange zvakadaro, heino tsanangudzo dzemasvingo maviri emakiromita uye mitemo, pamwe chete nekushandura kwakaoma zvishoma.
Kurera Mitezo
Statute Mile:
- 1 SM = 1 609 mamita
- 1 SM = 5,280 mamita
- 1SM = .869 NM
Nautical Mile:
Rimwe nautical mile (NM) sezvinotsanangurwa neA NOAA se: "Chikwata chemafaro chinoshandiswa mumagungwa ezvokufamba uye maruva ekufananidzira. Iyo yakaenzana ne 1.15 mamiriyoni kana 1,852 mamita. Ichowo ihwo hurefu hwemaminiti 1 emakero. "
- 1 NM = 1,852 mamita
- 1NM = 6,076 tsoka
- 1NM = 1.151 mutemo maira
Munyika yenharaunda, nzvimbo inowanzowanikwa muwautical miles, kunze kwekuonekwa, iyo inowanzotaurwa kana kuti inotarisirwa mumitemo yemiraira.
Speed Measurements
Paunenge uchitsvaga neutical miles zvakakodzera kuona musiyano nemashoko anowanzo-anoshandiswa akadaro MPH uye mazano.
- MPH: Mumutemo mairaira, zviyero zvinokurumidza zvakapiwa mumakiromita neawa, zvakafanana nemotokari.
- Knot : Izvo zvakananga kukurumidza kuenzanisa munharaunda ndeye ruzivo. Imwe tsvina yakaenzana nemira imwe yeautical neawa. Zviratidzo zvemhepo pazvikwata zvinowanikwa mumarota.
