– An Air China aircraft departing from Hong Kong to Dalian, China, reportedly dropped 10,000 meters last night (July 10), due to a loss of pressure in the cabin, reported The Star. At the time, the pbadengers were asleep, suddenly in front of them fell oxygen masks.
Based on the FlightRadar24 tracking site, 30 minutes after takeoff from Hong Kong International Airport, the Boeing 737 was beginning to fall at 7:40 am between Shantou and Xiamen.
The airline confirmed similar results, indicating that the aircraft had an initial fall of 14,100 feet in four and a half minutes, from 35,000 feet to approximately 10,000 feet, before climbing to an altitude of cruise.
According to the South China Morning Post, a sudden drop in altitude triggered the release of an oxygen mask from the cabin ceiling. A message on Weibo said: "The announcement of the badpit says that the ability to increase oxygen in the cabin does not work, so the plane loses pressure."
Weibo even posted a photo of himself wearing an oxygen mask and putting his thumbs in the air, convincing the netizens not to worry, when he said that the problem was solved as the plane approached Xiamen. The plane then went to Dalian successfully without any report of injury.
A professional pilot with more than 25 years of experience explains that any pressure drop in the cabin will cause the pilot to descend to 10,000 feet. "This is what is considered a safe and breathable atmosphere for pbadengers, and then the captain must make a decision."
"I would say that in almost every case you want to land as fast as you can, but that depends on what happens in the plane and what the pilot's checklist says." [19659008] "In many cases, you announce an emergency situation and you land at the most appropriate airport."
