Cabin Altitude Vs Real Altitude

---------------------------------------------
The difference between these two Altitudes is huge.
The Real Altitude of an Airplane is the difference expressed in feet between the Aircraft and the Mean Sea Level.
The Cabin Altitude is the Altitude, inside the Cabin that you feel when you fly.
In an unpressurized Aircraft, these two altitudes are the same however, when the Aircraft has the performance to climb high, let’s say above 10000 feet the Cabin should be pressurized.
Why? Because at high altitudes the air is less dense and we cannot survive for a long time at very high altitudes, such as 20, or 30 thousand feet.
An Airline Jet, such as the Airbus A320, can easily fly above 30000 feet, thus for its occupants, in order to survive, it is required a pressurized cabin where the air is dense enough.
So, the Cabin Altitude is the Altitude expressed in feet that the people on board are feeling, usually, it is between 5000 and 7000 feet at around 30000 feet or above.
The Pilots need to monitor the cabin altitude because if there is a problem with the pressurization system an Emergency descent is required immediately.
The target is to always maintain the Cabin Altitude below 10000 feet.

Hi thank you for your nice videos but I'm asking is there a way to determine the real aircraft altitude just from the cabin altitude or cabin differential pressure thank you

[@WilliamArnauts]

very good explanation, thanks a lot!

[@PILOTCLIMB]

You are very welcome!

[@ahmedgamer6311]

keep going captin you are amazing please give us more useful info.

[@PILOTCLIMB]

Thanks for your support.. more videos soon

[@therated661]

Thank you!

[@PILOTCLIMB]

You are very welcome!

Good information. I remember many years ago I took a hiking altimeter on a flight and watched the altitude change as we climbed out from takeoff. The altitude starter to increase until it reached 8000 feet, and then it stayed at 8000 feet all the way up to cruising altitude. It was very interesting to actually see it level off, even though we were still climbing.

[@PILOTCLIMB]

Great Point! Thanks for watching!

[@flightdeckq400pilot4]

Good one Captain Diff press = cabin press - atmospheric pressure?

[@PILOTCLIMB]

Thanks for watching! You can see it also like that!

[@user-bx6ts8en5p]

What if u explained about cabin alt. setting

[@PILOTCLIMB]

Hey, I take your suggestion into consideration for a future content

[@captsonko.9345]

thanks capt,my question is the cabin pressure part of the packs?

[@PILOTCLIMB]

You are very welcome! The packs are essential for air conditioning and pressurisation..

[@cptsbn]

From what i know, cabin pressure must be maximum 8000ft, correct?

[@PILOTCLIMB]

The cabin pressure must remain below 10000 feet and respect a limitation of differential pressure. However this limitation can change depending on the aircraft type

[@anand-menon]

I wonder how they maintain cabin altitudes of 4100 ft in jets like the Gulfstream G650ER which has a ceiling of 51000 ft. That's a LOT of pressure difference...

[@PILOTCLIMB]

Yes, but it depends on the Aircraft structure... The lower the cabin altitude the better the confort for its occupants...
