Airbus A320 Looses Pressurization In Flight.

Thu Oct 14, 1999 7:52 am

Hi I'm Ben
I read in "Le Soir", a Belgian daily newspaper, an article about an Air Belgium A320 loosing cabin pressure at Flight Level 310 or 350 (yes, it said in the article 10000m which is just equal to 33000ft, but flying westbound it must have been either 31000ft or 35000ft). Flight 512 took off from Heraklion (Greece) and was on its way back to Brussels when the aircraft lost cabin pressure due to a pressurization system malfunction. The pilots went into a quick dive right away and two minutes later they brought the A320 down to less than 10000ft where one can breathe normally, it is the correct emergency procedure to follow when there is a loss of pressure in the cabin. The A320 made safely an emergency landing somewhere in Italy.
Did anyone hear about this?

This is the correct procedure for pressurisation faliure, rapid descent to about 10,000ft. As for the 'two minutes later' bit, well that is an exggeration, we do it in about 7 minutes. It is bascially done because the oxygen supply for the passengers doesn't last very long (about 30 minutes if I'm not mistaken).

Phil330,

I had always heard that O2 generators last about 15 minutes, not 30. Can you clarify for me?

To add an addendum to Phil330's post--

The pilots are required to don the oxygen masks immediately and they usualy have more oxygen than the passengers. In addition, the oxygen that is fed to the cockpit is different. The masks are built to different specs.

I believe that the passenger masks are only required to 10,000' specs, if I'm not mistaken.

It's always been "pilots first, pax second." Sorry folks...

Neil is correct, the flightdeck oxygen supply is fed from an entirely alternative system to that supplied to the passengers. We get about 3 hours from ours, the passengers get more like 30 minutes. I cannot clarify the actual figure, I imagine it varys from plane to plane anyway.
