I-FAA kunye ne-ICAO Regulations yokusetyenziswa kwe-Oxygen kwi-Aircraft Unpressurized

Abasemagunyeni beenqwelomoya njenge FAA (Federal Aviation Administration) kunye ICAO (I-International Civil Aviation Organisation) igunyazisa iimfuno ezingqongqo zeoksijini ukuqinisekisa ukhuseleko kwimisebenzi yomgangatho ophezulu:

• Ngaphezulu kwe-12,500 iinyawo ze-MSL – Abaqhubi beenqwelo-moya kufuneka basebenzise ioksijini eyongezelelweyo emva kwemizuzu engama-30 yokuba sesichengeni.
• Ngaphezulu kwe-14,000 iinyawo ze-MSL – Abaqhubi beenqwelomoya kufuneka basebenzise ioksijini ngalo lonke ixesha.
• Ngaphezulu kwe-15,000 iinyawo ze-MSL – Ioksijini kufuneka inikwe bonke abakhweli.
• Ngaphezulu kwe-25,000 iinyawo ze-MSL – Iimaski ze-oksijini ezingxamisekileyo kufuneka zibekhona ukuze zihanjiswe ngokukhawuleza kwimeko yoxinzelelo lwekhabhinethi.

Kwiinqwelo-moya ezixinzelelekileyo, umngcipheko uyancipha kakhulu, njengoko i-cabin pressurization igcina indawo yokuphefumula. Nangona kunjalo, kwimeko yokunciphisa ngokukhawuleza, abaqhubi beenqwelo-moya kufuneka behle kwindawo ekhuselekileyo ngokukhawuleza ngelixa besebenzisa iimaski ze-oxygen eziphuthumayo.

Iziphumo zeHypoxia kunye nendlela abaqhubi beenqwelomoya abaNciphisa ngayo imingcipheko yeOxygen

I<em>Hypoxia inokubangela ukuba umqhubi wenqwelo-moya angakwazi ukwenza izigqibo, abone izisongelo aze aqhube inqwelo-moya ngokukhuselekileyo. Iimpawu ziquka:

• I-hypoxia ephakathi: Ukudinwa, isiyezi, kunye nokuncipha kokubona ebusuku.
• I-hypoxia ephakathi: Ukubhideka, ukungakwazi ukwenza izigqibo, kunye nokulahleka kolungelelwaniso.
• I-hypoxia enkulu: Ukungabikho zingqondweni, okukhokelela ekungakwazini ukuba akulungiswanga ngokukhawuleza.

Ukunciphisa umngcipheko we-hypoxia, abaqhubi beenqwelomoya balandela iinkqubo ezingqongqo:

• Iitshekhi inkqubo yeoksijini yangaphambi kokubhabha ukuqinisekisa ukufumaneka kunye nomsebenzi ofanelekileyo.
• Ukubeka iliso kwi-cabin pressurization ukuthintela ukuncipha kweoksijini kwiindawo eziphakamileyo zokubhabha.
• Iinkqubo zokwehla ngokukhawuleza ukubuyisela amanqanaba omoya ophefumlayo kwimeko yokusilela koxinzelelo.
• Ukusebenzisa i-pulse oximeters ukulinganisa i-oxygen saturation ngexesha langempela.

Ngokuqonda iimfuno ze-oksijini kunye nokuqaphela ingozi yokuvezwa komgangatho ophezulu, abaqhubi beenqwelo-moya banokuthatha amanyathelo asebenzayo ukuqinisekisa ukhuseleko lwenqwelomoya kubasebenzi kunye nabakhweli.

isiphelo

Umphakamo udlala indima ebalulekileyo kuphapho, echaphazela yonke into ukusuka ekusebenzeni kwenqwelomoya ukuya kukhuseleko lomqhubi. Iindidi ezintlanu eziphambili zokuphakama kwenqwelomoya-ubude obubonakalisiweyo, ukuphakama koxinzelelo, ukuphakama kobuninzi, ukuphakama okwenyani, kunye nokuphakama okupheleleyo-nganye isebenzela injongo ekhethekileyo kwimisebenzi yenqwelomoya. Ukuqonda ukuba ezi mphakamo zidibana njani kunceda abaqhubi beenqwelo-moya bahambe ngendlela ekhuselekileyo, basebenzise amafutha afanelekileyo, kwaye bathobele imithetho yendawo yomoya.

Umlinganiselo ochanekileyo wokuphakama kwenqwelomoya ubalulekile ekugcineni ukwahlukaniswa okukhuselekileyo kumhlaba kunye nezinye iinqwelomoya. Izicwangciso ezifanelekileyo ze-altimeter, nokuba zisebenzisa i-QNH, i-QFE, okanye i-QNE, abaqhubi beenqwelo-moya banceda abaqhubi baphephe ukutolika okungafanelekanga okunokubangela ukuphulwa kwe-airspace okanye iimpazamo zokuhamba.

Ukongeza, ukuphakama kuchaphazela iimfuno zeoksijini, kunye nokuphakama okuphezulu kufuna ioksijini eyongezelelweyo kubaqhubi kunye nabakhweli. Imimiselo esekwe yi-FAA kunye ne-ICAO iqinisekisa ukuba abaqhubi beenqwelo-moya baxhotyiswe ukujongana nemingcipheko yokunciphisa i-oksijini, ngokukodwa kwiinqwelo-moya ezingaxinwanga okanye ukungaphumeleli koxinzelelo.

Ukuqonda iikhonsepthi zokuphakama kwenqwelomoya kubalulekile kuye wonke umqhubi wenqwelomoya. Ingaba uceba ukunduluka, ukuhamba ngenqanawa kwiindawo eziphakamileyo, okanye ukulungelelanisa imiphumo yokuphakama koxinzelelo, ukuqonda okuqinileyo kokuphakama kuqinisekisa ukusebenza okukhuselekileyo nokusebenzayo kwenqwelomoya.
