Has Your Cabin Ever Been Depressurised?

Thu Oct 19, 2006 8:22 am

In the safety instructions, one always hears of the possibility of depressurization of the aircraft with oxygen masks coming out.
Has such an event ever occured to you. If yes, we you told the reason for it and wahat was the general atmosphere on board ?

One time I was flying an AS MD-80 from SEA-ANC, this was about 1995-ish. We took off and flew for about 15 minutes when the pilot told us that the planes pressurization system failed. we were probably at about 10000-15000 ft. i noticed no difference and no one needed any medical assistance when we landed.

Yup . . . never on a commercial flight . . . but on Mil-Air - all the time.

I was airborne in a C-130 over Cook Inlet headed to ADQ some years ago and we 'lost' the seal on a rear jump door. No worries, quick descent and we were fine. VFR flight conditions that day.

And another C-130 out near OME a year or so later . . . we descended and then opened the rear ramp so some crazy people with parachutes strapped to themselves could get out.  no  faint 

So, one controlled and one not. Either way, a non-event really.

All the time! Otherwise there'd be some serious issues when the door's opened at the gate  Wink

never realised the oxygen masks fall down when they open the door bouncy

I think you will find that to allow the door to be opened at the gate, the cabin has to have been pressurized from what it was at cruise.

Have run the cabin height up to about 20,000ft on a test flight, using supplementary oxygen, and it seemed OK, but there again I was just sitting down. Found it to really interfered with the smoking though  Yeah sure

On climb out of Entebbe once had a short on the electrical bus bar which controlled the pressurization, so closing the discharge valves, and for a short time the cabin went down the mine. What made it worst was it was at night and the cockpit main lighting came off that bus bar too so we were in semi darkness

Am I right in thinking that Ryanair's old B732 aircraft were not allowed to fly any higher than 22,000ft because of pressurisation problems? I flew MAN-DUB on one and it felt like I could hear air rushing in through the gap in the cabin interior, not a good flight but I didn't notice any problem with the pressurisation even though we were at a restricted altitude.

this (recent) thread could be interesting for you, even the title doesn't sound like it would - just follow the discussion, it's getting quite specialiced about decompression:

Yup...

Quoting RootsAir (Thread starter):
the reason for it

I was onboard cleaning the aircraft for the next flight and the crew just got onboard and was preflight-ing the cockpit... I heard the PIC ask "What the hell is this switch set like this?" He must have bumped it or flipped it or something, then all the masks came down...

Quoting RootsAir (Thread starter):
wahat was the general atmosphere on board ?

The PIC was a little irked...his first sentence spoke aloud had more adjectives then verbs, nouns, and adverbs combined...
This isn't where I parked my car...
