Thank you!

Thank you!

Pressurization is based on delta pressure. Increasing cabin altitude in a manner so that delta pressure is increased. Cabin altitude is increased because actual aircraft altitude is also increasing, but in all to maintain delta pressure value.

You're welcome

Thank you! Smoke removal procedure doesn't ask pilots to set LDG elev to 10000 feet. It asks pilots to descend down to 10000 feet. Two separate things.

Planes Over Head yes it does. Set LDG elev to 10000 and descend to 10000, so the outflow valve will open when reaching 10000 ==> smoke go out.

+Aseel Algethmi Firstly thank you. Can you please elaborate your question. Didn't really get it.

Thank you!

Thank you!

The repressurization is done at a very gentle rate, because during go around you're generally at lower altitudes which doesn't really require that level of high pressurization, it's just to avoid the rotation surge. Yes airports can be below sea level too. Lot of airports in California and Netherlands for example. 14000 feet is to cater for high altitude operations where after specific approval of the manufacturer and regulator the aircraft can operate under monitored conditions. Not many airports above 14000 feet in the world.

Will have to check this

Thank you so much. There is no diagram or any graph for what you are asking, but an approximate and a generic list of values are given in CAB PR SYS 1+2 FAULT. It cannot be fixed for a simple reason because we are never flying in ISA conditions and it purely is dependent on actual outside conditions at that particular area that you're flying through.

Yes that's correct. And thank you!

@@poh Fcom has so much things to absorb so im using your notes because i feel it's similar to the fcom and ill read on fctm for flight purposes

Maximum differential pressure is 8.06 and 8.6 is safety valve operating limit.

@@poh Okay Thanks for clarifying! I told my friends about your page because i told them its similar to the fcom since some are lazy to finish 1000 pages so i think they'll find this really helpful since you based it off fcom

Thank you

In your question I didn't understand the context of "back to normal again". If you could elaborate.

@@poh hello there. What I meant was if in the event the cabin pressure was compromise either by the pilot or some unfortunate event. How can one adjust back the setting for cabin pressure on high altitude flight? Is there like a setting that would auto adjust it based on the altitude the aircraft is flying?

For whatever reason if there is a sudden pressure drop (beyond the threshold which is triggered by ECAM), there is no procedure to reset it back and all even if aircraft seems to indicate its okay now. You first simply have to descend and decide later. And if the computers are available they will auto adjust. If computers not available then you've to manually adjust it yourself. But if there is a massive damage to the hull, nothing will work irrespective of the situation.

@@poh thank you for the information👍

Cargo bays are mandatorily pressurized. No option to that. You'll get a diagram in DSC-20-20.

@@poh Great, I found the diagram, I knew it was in there somewhere. Thanks a lot

You're welcome

Sorry I don't deal with AME papers.

EASA part 66 blogspot Search on google

Depends on where you are, if you're maintaining level then you need to shut the outflow valve and cabin altitude will drop. Nothing will happen to safety valves.

@@poh oooo ok thank you verymuch
