Nautical Mile, monga gawo loyesa, poyamba linkatchulidwa ngati mchitidwe wapadziko lonse ku Monaco mu 1929 ku Msonkhano Woyamba Wodabwitsa wa Zachilengedwe. Zisanayambe, panalibe chiyeso cha mayiko onse choyesa kutalika kapena poyenda m'madzi kapena, kapena chofunika kwambiri, pamadzi.
Dziko la United States silinagwire ntchito ya Nautical Mile mu 1929 koma idadumphira mu 1954 ndikuzindikira mchitidwe wogwiritsidwa ntchito padziko lonse.
(Miyendo yokhala ndi nthiti, yovomerezeka malinga ndi chiwerengero cha dziko lapansi, ndi yofanana ndi mphindi imodzi ya chigawo ndipo ndi yayitali kuposa lamulo loyendera dziko.)
Nautical Miles ndi Malamulo a Malamulo
M'dziko la ndege, njira yeniyeni yoyezera mtunda ndi mtunda wamadzi. Komabe, mawu ofanana amatsegula chitseko chothawa kuchoka ku chizoloŵezi. Chinthu chimodzi chokha chimagwiritsira ntchito malamulo osiyana siyana (SM) mosiyana ndi maulendo amodzi (NM) omwe amawunikira ku VFR, zomwe oyendetsa ndege amadziwa kuti zimakhala zochepa kwambiri pa nyengo ya VFR (14 CFR 91.155). mpweya ndi zamtunda.
Ndipo, pokhapokha mutangoyamba kumene, mumadziwa bwino mawu akuti VFR omwe akuyimira Malamulo Othawa Ndege. Vesi ya VFR imakhala yowonongeka kwambiri (komanso kutalika kwa mitambo) pamene ikuuluka pamwamba pa 10,000MSL (kapena, "kutanthauza nyanja," yomwe imayendera mapiri a ndege) chifukwa oyendetsa ndege amafunikira nthawi yochuluka kuti awone (ndi kupewa) Ndege zomwe zimatha kulowa mumtambo.
Kuchokera kwa Mtambo ndi Chinthu china Chokha
Chinthu chinanso chosiyana ndi lamulo lakuti miyendo yamadzi ndi yowonjezera chilengedwe ndipo ndiyeso yokhudzana ndi kutuluka kwa mtambo, yomwe imagwiritsanso ntchito malamulo amtunda (SM) m'malo mochita mafunde (NM). Chofunika chodziwitsidwa ndi mitambo ndi yovuta chifukwa ndi zovuta kudziwa ngati zochitika kunja kwa chitseko cha hanger zikugwirizana ndi zochitika zenizeni za nyengo, kapena ngati zochitika kuchokera pawindo la mpikisano likuyendetsa, pazomwezo.
Komabe, apa pali tanthawuzo la maulendo awiri amadzimadzi ndi maulamuliro, kuphatikizapo kusintha kochepa kophweka.
Zoyendera Pakati
Statute Mile:
- 1 SM = 1,609 mamita
- 1 SM = 5,280 mapazi
- 1SM = .869 NM
Nautical Mile:
Mtundu umodzi wa ma nautical (NM) monga momwe tafotokozera ndi NOAA monga: "Chigawo chapatali chomwe chimagwiritsidwa ntchito panyanja yamadzi ndi maulendo a m'nyanja. Ndilofanana ndi 1,15 miles kapena mamita 1,852. Ndilo kutalika kwa mphindi imodzi ya chigawo. "
- 1 NM = 1,852 mamita
- 1NM = 6,076 mapazi
- 1NM = 1.151 malamulo apadera
M'dziko la ndege , mtunda umakhala wowerengeka mumtunda wamadzimadzi, kupatula kuwonekera, komwe kawirikawiri kumanenedwa kapena kukonzedweratu m'malamulo amtunda.
Maseŵiro Ofulumira
Pofufuza makilomita amadzimadzi ndizofunikira kuzindikira kusiyana ndi mawu omwe amagwiritsidwa ntchito nthawi zambiri monga MPH ndi mfundo.
- MPH: Milime ya malamulo, miyeso ya liwiro imaperekedwa mu mailosi pa ora, mofanana ndi mu magalimoto.
- Zodziwika : Mwayendedwe kawirikawiri pa ndege ndi mfundo. Chinthu chimodzi ndi chofanana ndi kilomita imodzi yokha pa ora. Zizindikiro za ndege pa ndege zimagwiritsidwa ntchito muzitsulo.
