Vir\u0161 Atlantos oro uosto \u012fvyko pavojingas incidentas, kai du \u201eDelta\u201c l\u0117ktuvai priart\u0117jo pavojingai arti vienas kito per sud\u0117ting\u0105 skryd\u017ei\u0173 sek\u0105 t\u016bpimo ir kilimo metu. Situacija susiklost\u0117 tuo metu, kai \u012f Atlant\u0105 v\u0117lai vakare art\u0117jo reisas \u201eDelta 1568\u201c, anks\u010diau d\u0117l prast\u0173 or\u0173 kelioms valandoms nukreiptas \u012f \u010catanug\u0105.<\/p>\n
Art\u0117jant t\u016bpti \u012fgula pasteb\u0117jo, kad kitas orlaivis dar yra tako zonoje. Nors i\u0161 bok\u0161to buvo prane\u0161ta, kad takas atlaisvinamas, pilotai nusprend\u0117 nerizikuoti ir atliko go-around proced\u016br\u0105, tai yra nutrauk\u0117 t\u016bpim\u0105 ir v\u0117l pakilo \u012f auk\u0161t\u012f, kad pabandyt\u0173 t\u016bpti i\u0161 naujo.<\/p>\n
Tuo pat metu i\u0161 lygiagretaus tako pakilo kitas \u201eDelta\u201c l\u0117ktuvas, reisas \u201eDelta 2472\u201c. Skryd\u017ei\u0173 vadovas abiem \u012fguloms nurod\u0117 sukti \u012f de\u0161in\u0119 ir kilti iki 4 000 p\u0117d\u0173, tai yra ma\u017edaug 1 220 metr\u0173, ta\u010diau d\u0117l manevr\u0173 j\u0173 trajektorijos \u0117m\u0117 kirstis.<\/p>\n
Abiej\u0173 orlaivi\u0173 kabinose beveik i\u0161kart suveik\u0117 TCAS, bortin\u0117 susid\u016brim\u0173 prevencijos sistema, kuri pagal transponderi\u0173 duomenis \u012fvertina art\u0117jimo rizik\u0105 ir pateikia pilotams ai\u0161kius nurodymus d\u0117l i\u0161vengiam\u0173j\u0173 veiksm\u0173. Aviacijos taisykl\u0117s numato, kad TCAS nurodymai turi pirmenyb\u0119 prie\u0161 skryd\u017ei\u0173 vadovo komandas, tod\u0117l pilotai privalo juos vykdyti.<\/p>\n
Pagal \u201eFlightradar24\u201c duomenis artimiausiu momentu l\u0117ktuvus skyr\u0117 apie 1 800 p\u0117d\u0173, arba ma\u017edaug 550 metr\u0173, horizontaliai ir 600 p\u0117d\u0173, arba apie 180 metr\u0173, vertikaliai. Tai rei\u0161kia, kad tiesia linija atstumas tarp orlaivi\u0173 siek\u0117 ma\u017edaug 580 metr\u0173.<\/p>\n
Nors tiesioginio susid\u016brimo gr\u0117sm\u0117, sprend\u017eiant i\u0161 vie\u0161ai aptariam\u0173 duomen\u0173, nebuvo fiksuota, tokie atstumai laikomi ma\u017eesniais nei \u012fprastai siekiama minimali separacija, ypa\u010d kai skryd\u017eiai vykdomi pagal IFR taisykles. Oro uosto prieigose paprastai taikoma didesn\u0117 radarine separacija paremta tvarka, o vertikali separacija standartin\u0117mis s\u0105lygomis siejama su nustatytais auk\u0161\u010di\u0173 intervalais.<\/p>\n
Incident\u0105 ketina vertinti Federalin\u0117 aviacijos administracija, kuri ai\u0161kinsis, ar buvo laikytasi proced\u016br\u0173 ir ar ne\u012fvyko separacijos pa\u017eeidimas. Pastaraisiais metais JAV institucijos vie\u0161ai akcentuoja, kad augant skryd\u017ei\u0173 intensyvumui did\u0117ja ir skryd\u017ei\u0173 saugos \u201eartimo priart\u0117jimo\u201c atvej\u0173 analiz\u0117s svarba, o TCAS i\u0161lieka viena kritini\u0173 paskutin\u0117s grandies priemoni\u0173, padedan\u010di\u0173 i\u0161vengti katastrof\u0173.<\/p>\n","protected":false},"excerpt":{"rendered":"
