Cabin Altitude

I'm getting a Cabin Altitude warning on the 767 in flight from KATL to SKBO.  The landing altitude of the airport is 8358', which I set on the overhead.  Pressurization panel shows 8400'

No windows/doors open.  Any ideas what's causing this?

Thanks,

Daniel

Could it be because the altitude air pressure at the arrival airport is lower than the cabin pressure at Cruise Altitude? Maybe by setting the landing altitude to 8400 feet, the cabin pressure is considered too low for passenger comfort.
Not sure how this works in real life, I guess a real world pilot, who has flown to Bogota, could answer your question better. Undecided

Okay, thanks. So I guess that's assuming the logic in the CS plane is working correctly?

Are you setting your Cruise Altitude on the overhead pressurization panel as well?

There's no way to do this in a 757 or 767, it receives cruise altitude from the CDU/FMS only. You do however have to reset the landing altitude window for every flight / descent.
