<prompt> Fingqa isihloko: CNN Ngemva konyaka, kusazwakala kungenakwenzeka: Indiza eyinkimbinkimbi ebiza izigidi ezingu-270 zamaRandi eyayithwele abantu abangu-239 iyanyamalala, ishiya izinkomba ezimbalwa kakhulu zokuthi yayikuphi. Kodwa ingabe ngempela inhlekelele yezindiza iMalaysia Airlines Flight 370 kwakufanele ibe imfihlakalo kangaka? Mhlawumbe akunjalo. Imibuzo engaphenduliwe - kanye nokuhlukumezeka okuhlangenwe nakho kwabangane nomndeni wabagibeli kanye nabasebenzi be-Boeing 777-200ER - konke bekungagwenywa ukube ubuchwepheshe obusebufakazelwe bebukhona. Kungakhathaliseki ukuthi uyakholelwa noma cha, ezweni lethu lanamuhla, ubuchwepheshe bokulandelela izindiza abukangeni ekhulwini lama-21. Ngokwesibonelo, cabanga nge-GPS. Kungani abaqondisi bezindiza bengalisebenzisi ukuqapha njalo zonke izindiza ezihamba ngezindiza? Kuthiwani ngokuxhumana namasathelayithi? Kungani zonke izindiza zingathumeli lokho okubizwa ngokuthi idatha yebhokisi elimnyama kuma-satellite ngesikhathi sangempela? Lobu buchwepheshe buyatholakala. Yebo, kuyabiza, kodwa kanjalo nokusesha amakhulu ezinkulungwane zamakhilomitha-skwele olwandle olukhulu. Ake sihlaziye. I-Flight 370 yayinezindlela eziyisishiyagalombili zokuxhumana nomhlaba ngenkathi indiza: Imisakazo emihlanu ephezulu kakhulu nephakeme kakhulu engadlulisa futhi yamukele ukudluliswa kwezwi nedatha. Ama-transponders amabili angathumela imininingwane yokuhlonza nokuphakama ezikrinini ze-radar zokulawula ukuhamba kwezindiza. Umthumeli oyedwa wesathelayithi ongadlulisa futhi wamukele imiyalezo yombhalo nezingcingo. Naphezu kwalobu buchwepheshe, izwe lalahlekelwa umkhondo wendiza enegama eliyimfihlo lomkhakha wezindiza i-MH370. Ukuze uqonde ukuthi kungani, kumelwe uqale wazi okuncane ngobuchwepheshe nangezikhala ezikulesi simiso. Ezingxenyeni eziningi zomhlaba, abaqondisi bezindiza basalandela izindiza nge-radar - esebenzisa ubuchwepheshe obuqala ngawo-1940. I-Radar inokwethenjelwa, kodwa ilinganiselwe. Inezikhala ezinkulu ezindaweni ezimboziwe. Izindiza ezindiza ngaphezu kwamamayela angaba ngu - 200 ukusuka ezweni phezu kwezilwandle azilandelwa izikrini ze - radar zokulawula ukuhamba kwezindiza. Ochwepheshe bathi i-radar ihlanganisa amaphesenti amabili noma amathathu kuphela endawo yomhlaba. Konke okunye kuyizwe elingenamuntu. Uma ama-transponder endiza evaliwe,...  <response>: Ubuchwepheshe besimanje bokulandelela bungase busisize ekuxazululeni imfihlakalo yeMalaysia Airlines Flight 370. Ngemva konyaka i-MH370 inyamalale, ukulandelela izindiza kusalokhu kufana ncamashi. Iningi lezindiza lisebenzisa ama - radar asemhlabeni esikhundleni sama - satellite; ukulandelela phezu kwezilwandle akuvamile, okungenani.
