"Ibhokisi elimnyama" elisha lizosiza ukuxazulula izimfihlakalo zokuphahlazeka komoya

Lapho indiza yesimanje iwa ngokuzumayo isuka esibhakabhakeni, ukusesha kwebhokisi elimnyama kuvuliwe. Kunjalo ekulahlekelweni okudabukisayo kwendiza i-Air France 447 phezu kwe-South Atlantic ngoJuni 1, 2009. Lelo bhokisi elimnyama alizange litholakale futhi lisesendaweni ethile ezansi ne-Atlantic Ocean.

Izinkomba ezimbalwa ezikhangayo ezadluliselwa zisuka endizeni zazinganele ukwenza noma yini ngaphezu kokuphakamisa amathuba amaningi, kodwa akukho okucacile ngokuthi kungani indiza ebibonakala isebenza ngokujwayelekile, yehle kungazelelwe ngaphandle kokuxhumana okuvela endizeni. Ijubane okwenzeke ngalo le nhlekelele laliyobonisa ukuthi kungakhathaliseki ukuthi kwenzekani, indawo yendiza yayinesexwayiso esincane noma angenaso salokho okusobala ukuthi ukwehluleka okuyinhlekelele okuzumayo, kwesistimu yonke.

Ukuphishekela izimpendulo kwakuhlanganisa ukuthunyelwa kwezimpahla eziningi, ezihamba emoyeni nezihamba emanzini, ukuze kuzanywe ukuthola i-Flight Data Recorder kanye ne-Cockpit Voice Recorder ngaphansi kwamamayela wamanzi kwenye yezindawo ezijulile olwandle. Kwachithwa izigidi, nokho womabili amabhokisi asala phansi olwandle, kanye nezimpendulo zalokho okwenzeka ngempela.

Eminyakeni eyisithupha edlule, i-Western Avionics yaseCalgary, eCanada, yaqala ukuthuthukiswa kwenkundla yeseva engenantambo etholakala emoyeni eyayihloselwe ukuhlinzeka ngolwazi lokulandelela olutholwe ebhasini le-Flight Data Recorder (FDR) ngenjongo yokunakekela kanye nezinjongo Zokuqinisekisa Ikhwalithi. Ngesikhathi sokuthuthuka kwayo, amakhono e-CommuniCube (C3) afinyelele ezingeni lapho isisebenza khona njenge-FDR ezimele, ekwazi “ukulalela” ngobuhlakani futhi ibike noma yikuphi ukwephulwa kokubekezelelana, kusukela ekuqaleni okushisayo kuya ekufikeni okunzima, futhi ithumele leyo datha emuva isisekelo sokunakekela ngesathelayithi uplink ngaphandle kwabasebenzi abathatha isinyathelo ukubika ukwephulwa komthetho. Uhlelo ludizayinelwe ukuthi lusebenze ngokuzenzakalelayo noma nini lapho ipharamitha echazwe umsebenzisi yeqiwa, noma ingaqalwa mathupha abasebenzi basedekhini yendiza nganoma yisiphi isikhathi.

I-C3 ifakwe ngempumelelo kukho konke kusuka kumawele alula kuya kumajethi esifunda futhi isebenza emazweni amaningi emhlabeni jikelele.
Ukuthuthukiswa kokucindezelwa kwedatha nokuxhumana ngesathelayithi sekufike ezingeni lapho i-C3 ikwazi ukuxhumana - bukhoma - ulwazi oluvela ebhasini le-FDR - kanye nanoma yiluphi ulwazi olwengeziwe umsebenzisi alubona lubalulekile ekusebenzeni kwabo. Isibonelo, ezicelweni ze-EMS, ulwazi lwezokwelapha lwesiguli lusakazwa ngaphambi kwendiza ukuya esibhedlela. Izinhlelo zokusebenza zomlilo zinedatha eshintshwayo, umoya uye emoyeni, phansi ngezinjongo zokuxhumanisa ukulwa nomlilo, futhi izindiza zezohwebo zisebenzisa i-C3 yokulandelela i-FOQA (Flight Operations Quality Assurance).

“Nakuba i-C3 ingeyona indawo enesitifiketi ethatha isikhundla se-FDR, okuzohlala kuyizwi lokugcina mayelana nedatha yendiza egibele, i-C3 inganikeza isithombe sesibuko salokho i-FDR eyayikuthola cishe bukhoma kumsebenzisi ochazwe. i-terminal noma kuphi emhlabeni. Lapho i-C3 izwa noma yikuphi ukuziphatha okungavamile, iqala ngokushesha ukuthumela idatha, iqala ngendawo ye-GPS yamanje yendiza, ngaphandle kokufaka umshayeli,” kusho u-Greg Taylor we-Western Avionics, ukuthuthukiswa komkhiqizo.

Kodwa okubaluleke kakhulu, i-C3 izodlulisa konke ekuzwa ebhasini le-FDR, bukhoma, kuze kube yilapho isimo sesixazululiwe, noma kuze kube yilapho ingasakwazi ukwenza kanjalo. Endabeni yendiza i-Air France 447, kungenzeka ukuthi lolu lwazi luhambe ibanga elide ekuxazululeni enye yezinhlekelele zezindiza ezididayo eminyakeni edlule.
