民航消息：6月10日，澳大利亞航空（QANTAS）從洛杉磯飛往墨爾本的QF94航班在太平洋上空遭遇渦流，機上數百名乘客經(jīng)歷了長(cháng)達十秒鐘“俯沖”的驚魂時(shí)刻。
據悉，這一戲劇性的危險場(chǎng)面主要是由另一架澳航飛機造成的“尾流湍流”引起的。
乘客Janelle Wilson透露，這架“載客四分之三”的飛機從洛杉磯起飛不到兩小時(shí)，突然遭遇強烈的湍流，隨后失控翻轉，猛然向海洋俯沖長(cháng)達10秒鐘。
Wilson形容當時(shí)的感覺(jué)就像坐過(guò)山車(chē)一樣，乘客瞬間被從座位上抬起來(lái)又直直摔下去?！帮w機下墜時(shí)我感覺(jué)胃里翻江倒海，我尖叫著(zhù)握住鄰座女士的手，只能這樣等著(zhù)，一度以為飛機就要墜毀了。那真的太可怕了”
幸運的是，這架核載484人的飛機最終并無(wú)人受傷。航班于周二早上8點(diǎn)安全降落墨爾本，比原定時(shí)間晚點(diǎn)半小時(shí)。
根據SKYbrary飛行安全專(zhuān)家的說(shuō)法，另一架飛機飛行中產(chǎn)生的尾渦引起了嚴重湍流，而這這兩架澳航航班之間沒(méi)有留出足夠的飛行間隔。
然而，澳航發(fā)言人堅稱(chēng)，他們并沒(méi)有違反飛行間隔標準，這兩架A380飛機在1000英尺的飛行高度上相隔有20海里。
Passengers have described the terrifying moment a vortex sent their Qantas flight into a 10-second “nosedive.”
Hundreds of horrified travelers held hands -believing they were about to die as the aircraft suddenly dropped over the Pacific Ocean on Sunday.
The dramatic ordeal afflicting passengers on the QF94 from Los Angeles to Melbourne is understood to have been caused by the vortex, or “wake turbulence” caused by another aircraft which took off just two minutes earlier.
QF94 passenger Janelle Wilson told The Australian the “three-quarters-full” plane suddenly entered a “free fall nosedive … a direct decline towards the ocean” for about 10 seconds.
“It was between 1? and two hours after we left LA and all of a sudden the plane went through a violent turbulence and then completely up-ended and we were nose-diving,” Wilson told the newspaper yesterday.
“We were all lifted from our seats immediately and we were in a free fall. It was that feeling like when you are at the top of a rollercoaster and you’ve just gone over the edge of the peak and you start heading down.
“It was an absolute sense of losing your stomach and that we were nosediving. The lady sitting next to me and I screamed and held hands and just waited but thought with absolute certainty that we were going to crash. It was terrifying.”
Thankfully nobody onboard the aircraft, with a seating capacity of 484, was injured.
The QF12 flight took off from Los Angeles at 11:27 p.m. Sunday night, 57 minutes behind schedule. While the QF94 service, which departed at 11:29 p.m., 49 minutes late, landed safely but 30 minutes late in Melbourne at 8 a.m. on Tuesday.
According to flight safety experts at SKYbrary, wake vortexes cause severe turbulence, which is generated by the passage of another aircraft in flight. Basically, there is not sufficient separation between the flights.
However, a Qantas spokeswoman told The Australian there had been no breach of separation standards because the two A380 aircrafts were understood to be apart by 20 nautical miles and 1,000 feet in -altitude.
