Qaysi sharoitda vertolyot aholi punktlari bo'ylab past balandlikda uchishi mumkin?

Kecha, Energetika boshqarmasi Boston va uning atrofidagi past balandliklardagi harbiy vertoletni uchirdi, uning atrofida esa http://nnsa.energy.gov/mediaroom/pressreleases/nnsa-karaktsionerlik-sharalish-shirma-shunoslik-survey -over-boston-maydon-0 "rel =" nofollow noreferrer "> radiatsiya o'lchash uchun bir turdagi eksperimentning qismi sifatida .

Men bu suv samolyotlaridan birini "Watertown" orqali o'tayotganimda ko'rib qoldim va aslida u menga o'tdi. Bu juda xavfli balandlikda ishlagan. Har qanday vosita buzilishi ko'plab o'lim holatlariga sabab bo'lar edi. Odatda, samolyotlar 500 metrdan pastroq tezlikda uchishmaydi va vertolyotlar 500 metrdan pastga tushganda, ular odatda ehtiyotkorlik bilan va xavfsizligini biladigan hududlarda harakat qilishadi. 100 futlik AGLda zich shaharda yuqori tezlikda uchadigan katta vertolyotga ega bo'lishi juda xavfli va FAA qoidalariga zid.

Vertolyot turini yangiliklardagi uyg'unlik turi emas edi, bu Chinook edi. NASA bir oz teginish vertolyot bilan suratga olish uchun va keyin katta Chinook atrofida uchib ketish uchun, men o'zlarini juda aldamchi deb o'yladim.

Men bu borada uchuvchisiz shikoyat qilmaganman, chunki men bu kabi xavfli faoliyatni amalga oshirish uchun maxsus "ruxsatnoma" yoki maxsus vaziyat yaratilgan deb hisoblayman. Bu erda va shartlar bilan bog'liq huquqiy vakolatlarini kimdir biladimi?

BTW, men NOTAMlarni tekshirmadim va pochta qutisimdagi har qanday NOTAMni olmadim, shuning uchun kimdir foydali bo'lishi uchun NOTAMni bog'lashi mumkin.


Update: this may have been a medevac flight, with emphasis on the word "may". Apparently, in some cases military helicopters are used for medevac flights to Burlington. However, if it was, the pilot was hot dogging and off the normal routes, both of which are serious regulation violations, but nevertheless I am told some military pilots disregard the rules.

NASA bu haqda CH 47ga ega emas: airbornecience.nasa.gov/aircraft And a CH-47 - uzunligi 98 fut bo'lgan (rotorli), shuning uchun erning ustidagi samolyot uzunligi haqidagi da'vo ham mumkin emas (lekin imkonsiz bo'lsa ham)

Chinook 147 raqamli qo'ng'irog'i emas, balki Bell-100 edi. Agar Chinook dvigatelining buzilishi bo'lsa, unda siz 100 futdan AGLga uchib ketishingiz mumkin bo'lsa, u halokatli vaziyatni keltirib chiqaradi.

@RonBeyer Ushbu qoidada Watertown kvadratidan 100 metr balandlikda uchadigan hech narsa yo'q. Bu kabi "belgilangan marshrut" yo'q. "Ruxsatnoma" ga qadar men buni bilaman va men buni mening savolimda aytgan. Men "ruxsatnoma" nima ekanligini bilmoqchiman, bu kabi juda xavfli operatsiyani amalga oshirish imkonini beradi.

Har qanday vosita buzilishi bir nechta halokat holatini yaratgan bo'lardi. Menimcha, bu butun savolni bekor qiladigan nuqsonli asosdir. Chinook uchun yuqori tezlikda oldinga uchadigan parvozda vosita buzilishi to'liq nazorat qilinadi - agar bunday bo'lmasa, bunday turdagi sertifikat olinmaydi. Menga kechirasiz, lekin butun xabarni jiddiy tergovdan ko'ra ko'proq fahm kabi o'qiydi.

Men chinookda, taxminan 50 futdan va taxminan 70ktsdan, simulyatsiya qilingan vosita buzilishida edim. Sizmi? U balandligi tezda yo'qolmaydi. Bu holatda (o'rmonda yong'in o'chirilishi orqali) qutqarish yana normal darajada ko'tarilish edi, shuning uchun ikkinchi dvigateldan chiqib ketish mumkin bo'lgan avtoto'ldirish mumkin edi.

Men bu haqda uchuvchi shikoyat qilmaganman, chunki men bunday maxsus "ruxsatnoma" mavjud deb o'ylayman yoki istalgan istisnosiz bu xavfli faoliyatni amalga oshirish uchun yaratilgan. bu haqda kapotingizda bir ari aniq aniqlangan. Nimaga xabar bermayapsiz? faa.gov/contact

Qanday qilib bilasizmi, bu 100 fut? Chinooks katta, siz osongina uning balandligi noto'g'ri qarorga kelishingiz mumkin.

Umuman olganda, dastlab mantiqsiz bo'lib tuyulsa-da, ko'plab vertolyotlar 100 dyuym va 100 dyuymli AGL da motorni ishdan ketkazish uchun yaxshi imkoniyatga ega. Shunday qilib, hovering o'rniga yuqori tezlikda sayohat qilish, ehtimol, siz ko'rgan vertolyot qidiruvi buzilishidan qutulish imkoniyatini oshirdi. Izoh uchun en.wikipedia.org/wiki/&hellip ga qarang. .

I have no idea about the specific flight you saw, but the general answer to your question about operating legally below the minimum safe altitudes in 14 CFR 91.119 is that the FAA can grant a waiver allowing lower flight. The waiver process says that to get a waiver to 91.119(b) (flight over congested areas) there must be a public interest reason but aircraft can't be lower than 500ft unless lives are at stake:

Vaqt chiqarishda talab qilingan balandlik mutlaq bo'lishi kerak   minimal, ammo shaxs yoki mulkdan 500 futdan kam bo'lmasligi,   inson hayotini saqlab qolish uchun kerak bo'lmaganda,

Haqiqatan ham, nima yuz berayotganini aytish uchun ko'rgan vertolyot haqida etarli ma'lumot yo'q, lekin haqiqatan ham 100 "AGL da Chinook bo'lganini taxmin qilar ekan, FAA jarayoniga ko'ra, hatto undan voz kechish uchun juda kam. Biroq, eng aniq tushuntirish, uni olib tashlashdir; vertolyotlar nuqtai nazari va havo tezligi oralig'ida chiqariladi va ba'zi qochqinlarning ehtimol nisbatan past va tez bo'lishi mumkin. Ehtimol, medevac parvozi (ular tez-tez yoritilgan) yoki logistika yoki qurilish bilan bog'liq bo'lgan bo'lishi mumkin; Agar siz N raqamini topsangiz, uni qidirib topishingiz mumkin.

Bu mening umumiy taassurotim edi. 500 metrdan pastga tushadigan no-no, shuning uchun men buni qanday amalga oshirayotganini tushunishga harakat qilaman. Men ko'rgan chopchi hech medevac parvozi emas edi.

@TylerDurden Nima uchun siz 500 metrdan pastga cho'zilib ketgan deb o'ylaysiz? Qanday asosda? Biz vertolyot operatsiyalaridan bahramand bo'lamiz, shunday emasmi? Va harbiy vertolyot operatsiyalari, ko'proq narsa. Men past darajadagi parvoz nima uchun taqiqlanganligi haqida nima yo'qotayotganimni bilishni istayman.

Sizning ta'rifingiz bo'yicha, "harbiy" Chinook tipli vertolyoti taxminan 100 futlik AGL atrofida tez-tez uchib ketgan.

- ikki marta takrorlanadigan savollarga javob: - vertolyot qanday ahvolda aholi punktlari bo'yicha past balandlikda uchishi mumkin?

  1. Firstly, under FAA regulations (more on this in a moment), helicopters are not generally subject to any specific altitude restrictions. See 14 CFR 91.119 Minimum safe altitudes: General.

    Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes:

    (a) Anywhere. An altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface.

    (b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.

    (c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

    (d) Helicopters, powered parachutes, and weight-shift-control aircraft. If the operation is conducted without hazard to persons or property on the surface—

    (1) A helicopter may be operated at less than the minimums prescribed in paragraph (b) or (c) of this section, provided each person operating the helicopter complies with any routes or altitudes specifically prescribed for helicopters by the FAA

    The FAA comments on this regulation:

    Helicopter operations may be conducted below the minimum altitudes set for fixed-wing aircraft. The reason? The helicopter's unique operating characteristics, the most important of which is its ability to execute pinpoint emergency landings during power failure. Further, the helicopter's increased use by law enforcement and emergency medical service agencies requires added flexibility in the application of many FAA provisions.

    Therefore, a helicopter may be operated at an altitude which complies with §91.119 (a) and (d), despite perhaps appearing to be otherwise to the unknowing observer.

  2. Secondly, military aircraft operations are generally not subject to the same FAA regulations that civilian aircraft operations are. Therefore a military helicopter operation, such as that which you describe, might well be operated under military aviation rules in disregard to rules that would otherwise govern civilian helicopter operations. See this answer regarding the FAA's jurisdiction—or lack thereof—over military aircraft operations.

Birgalikda ko'rib turganingizdek, siz tasvirlagan harbiy vertolyot operatsiyalari 14 CFR 91.119 ga muvofiq operatsiya qilingan bo'lishi mumkin va " Simonning yuqoridagi sharh , ehtimol edi; Biroq, harbiylar o'z qoidalariga muvofiq harakat qilishini ham ko'rib turibmiz. Sizning matningizdagi Bu erda berilgan huquqiy vakolati va shartlari haqida kimdir biladimi? savoliga javobni eng yaxshi deb hisoblash mumkin: "AQSh Hukumati tomonidan har qanday sharoitda muvofiq".

Tez, qisqa javob - bu bog'liq.

Esda tuting, bu erda ikki xil qoidalar mavjud.

  1. FARs, ular samolyotlarning ko'pchiligiga qo'llaniladi (Ruxsat etilgan qanot va Rotary qanot).

  2. Ommaviy foydalanish uchun samolyotlar - harbiy, mahalliy boshqaruv samolyotlari va uchuvchi. Ushbu samolyotlar va uchuvchilar, albatta, FAA'nın nazorat qilish/yönetmeliği ostida faoliyat ko'rsatmaydi.
