U\u00e7akta kabin bas\u0131nc\u0131 kayb\u0131 iki nedenle ortaya \u00e7\u0131kabilir; ya bas\u0131n\u00e7lama sistemi ar\u0131zas\u0131, ya da kabinde bas\u0131n\u00e7 kayb\u0131 yapacak bir ka\u00e7a\u011f\u0131n olmas\u0131 (kabin patlamas\u0131). Bilindi\u011fi gibi yolcu u\u00e7aklar\u0131 25-35 bin feet (8-10 km.) irtifada u\u00e7arlar ve kabin i\u00e7i de 5-7 bin feet irtifada tutulur. Bu irtifada d\u0131\u015f \u0131s\u0131 – 25-55 0C civar\u0131ndad\u0131r. Bas\u0131n\u00e7lama sistemi ar\u0131zas\u0131 olmasa bile, kabinde kap\u0131, pencere kopmas\u0131 veya kabin duvarlar\u0131n\u0131n herhangi bir yerindeki \u00e7atlak-k\u0131r\u0131lma olmas\u0131 durumlarda, bas\u0131nc\u0131 g\u00f6rece y\u00fcksek olan kabin i\u00e7i hava, bas\u0131nc\u0131n \u00e7ok d\u00fc\u015f\u00fck oldu\u011fu d\u0131\u015far\u0131ya do\u011fru kuvvetli bir r\u00fczgar bi\u00e7iminde hareket eder; hatta deli\u011fin b\u00fcy\u00fck oldu\u011fu hallerde bu ak\u0131m yolcular\u0131 bile d\u0131\u015far\u0131 s\u00fcr\u00fckler. Bas\u0131nc\u0131n b\u00f6ylesine aniden azalmas\u0131, bir patlama sesiyle birlikte havadaki nemi su buhar\u0131 (sis) haline getirir; ortal\u0131k toz-duman olur, \u0131s\u0131 birden d\u00fc\u015fer. Delik k\u00fc\u00e7\u00fckse, hava ve bas\u0131n\u00e7 kayb\u0131 s\u0131zma bi\u00e7iminde ve yava\u015f olaca\u011f\u0131ndan b\u00f6yle g\u00fcr\u00fclt\u00fcl\u00fc tablolar olu\u015fmaz, ama tehlike sinsice geli\u015fir. Bu durumda tehlike yaratan iki unsur, dondurucu so\u011fuk<\/strong> ve hipoksi<\/strong>dir (oksijensizlik). Hipoksi, solunan havadaki oksijen yetersizli\u011fine ba\u011fl\u0131 olarak geli\u015fen, bilin\u00e7 kayb\u0131 ve \u00f6l\u00fcme kadar g\u00f6t\u00fcren bir tablodur. Ba\u015f d\u00f6nmesi, g\u00f6rme bozukluklar\u0131, uyu\u015fma gibi belirtileri var ise de, alkol kullan\u0131m\u0131ndakine benzer bir keyif ve umursamazl\u0131k (\u00f6fori) yaratt\u0131\u011f\u0131 i\u00e7in pilotlar taraf\u0131ndan \u00e7o\u011funlukla fark edilmez. U\u00e7akta kabin bas\u0131nc\u0131n\u0131n ani veya tedrici kayb\u0131n\u0131 ikaz eden g\u00f6stergeler, bireysel oksijen soluma maskeleri vard\u0131r; ancak olay\u0131n pani\u011fi, \u00f6fori veya bilin\u00e7 kayb\u0131 nedeniyle oksijen solunmamas\u0131 da, ar\u0131za nedeniyle maskelere oksijen ak\u0131\u015f\u0131n\u0131n kesilmesi de olas\u0131d\u0131r. Helios u\u00e7a\u011f\u0131 37.000 feet irtifada iken bas\u0131n\u00e7lama ar\u0131zas\u0131 veya kabin patlamas\u0131 olduysa, m\u00fcrettebat ve yolcular – 55 0C \u0131s\u0131ya ve hipoksiye maruz kalacaklar, yolcular ya donarak \u00f6lecekler veya oksijen solumazlarsa 1-2 dakika i\u00e7inde hipoksiden bilin\u00e7 kayb\u0131na u\u011frayacaklard\u0131r. Bu kazan\u0131n olu\u015funu haz\u0131rlayan bir ba\u015fka olas\u0131l\u0131k, egzos ve di\u011fer kaynaklardan kabin i\u00e7i havas\u0131na kar\u0131\u015fan CO zehirlenmesidir; ancak bu olas\u0131l\u0131\u011f\u0131 destekleyen bir ipucu yoktur.<\/p>\n

Kazan\u0131n olu\u015fmas\u0131nda bunun pay\u0131n\u0131n olup olmad\u0131\u011f\u0131 bilinmemekle birlikte, bazen \u00e7ok k\u00fc\u00e7\u00fck bir u\u00e7u\u015f disiplinsizli\u011fi, bir k\u00fc\u00e7\u00fck uyar\u0131 \u0131\u015f\u0131\u011f\u0131n\u0131n dikkate al\u0131nmamas\u0131, b\u00f6ylesine dramatik sonu\u00e7lar\u0131n yarat\u0131c\u0131s\u0131 olabilmektedir.<\/p>\n
