Have You Ever Been On A Flight That Lost Pressure?

Tue Sep 02, 2003 12:53 am

Have you ever been on a flight that lost cabin pressure? I have never but I thought there were probably people who were. Happen to you?

No, but my good friend did.

EK68, B777 DXB-SIN over PEN. Terrifying and not something I'd like to repeat.

Pressurization in commercial airliners maintains the cabin pressure, operating at their maximum altitude, to an equivalent pressure that you would have at 8,000 feet (2,500 meters) elevation above sea level...

Loss of pressurization is an emergency, and a dire emergency if the airplane sustains an "explosive decompression" by a structural failure. The only possible recovery is (standard airline procedure) to make an "emergency descent" to an altitude at (or below) 14,000 feet (3,000 meters) as soon as possible...
xxx
When you are flying at some 36,000 feet (11,000 meters), should you have a sudden loss off pressurization, the human brain has only 15 to 20 seconds of "useful conciousness" left, because of lack of oxygen from the lungs. This requires the immediate use of oxygen masks, by the airplane's occupants.
xxx
The pilots have masks that may sustain life up to some 30,000 to 35,000 feet, but actually may not be that good... Sadly, the passenger oxygen masks can do very little to sustain life at high altitude, so do not count to much on these flimsy little masks... They are just effective enough to sustain life during an emergency descent... An emergency descent may take some 3 to 4 minutes to reach as safe altitude. It is a maneuver that is likely to increase the level of "panic" among passengers, since in many airplanes, speed brakes, landing gear down and extreme nose-down attitude, are extremely unconfortable for passengers...
xxx
Technically, transport airplanes are equipped with a warning system which tells the pilots of faulty pressurization, when the cabin exceeds 10,000 feet, and if the pressure is not recovered, all the masks in the passenger's cabin will drop automatically, when the pressure is further reduced to an altitude of 14,000 feet...
xxx
As a pilot, I have never experienced an explosive decompression, but I had a couple of partial loss of pressurization situations, which required the aircraft to be operated at lower altitudes. Pilots practice an emergency descent in simulators every 6 months, for training...

Hope that this provides you with some information about the subject...

ETA_Unknown, from the flight numbers was this at least 2 years ago?
Did you continue to SIN? or had an emergency landing?

Yes- at least 2 years ago. We dived to 10,00 feet and continued to SIN after circling PEN a dozen times while wearing oxygen masks during the dive.
