I was just coming to post and someone already had it up....
Assumption: Doors cannot be opened in flight 'at altitude' due to pressurization.
Question: Does the pressurization turn on/off automatically when descending to or reaching a designed altitude?
It seems this was below 1000 feet looking at the articles I saw.
Automatic pressure controllers will set to a value between 50 and 500 feet above field pressure altitude - so at some point in the approach the pressure on the outside will equal the pressure on the inside - this is maintained through landing.

Did you Chat GPT this?
I find it interesting people had "breathing problems". I wonder if it is mental or due to the shock of the guy opening the door. Probably both...
In one of my current airframes the Final Checks cannot be completed until pressurization drops below .7psi. I find this usually happens around 800 feet, give or take. That's still 80lbs of force pushing out on the door, and our door opens outward.Automatic pressure controllers will set to a value between 50 and 500 feet above field pressure altitude - so at some point in the approach the pressure on the outside will equal the pressure on the inside - this is maintained through landing.

I am reminded of this sad story of an American Airline flight attendant that may have been blown out a door because of some residual cabin pressure (A300) that made it difficult for the crew to open the entry doors while on the ground.

Doesn’t look like the masks dropped…. Also looks like the slide deployed and tore off.
I’ve never flown anything where the masks would drop unless the cabin altitude got to around 14,000 or so.Doesn’t look like the masks dropped…. Also looks like the slide deployed and tore off.
Parking brake set, split engine masters (to make the RPCU work), seat belt sign...The A300 and A310 series didn’t have the residual pressure warning light that you see installed on the entry door windows and emergency exits of later Airbus airplanes. It did become available later as a retrofit, as it was designed later than these jets. The A300/310s that were not converted, instead had a warning placard at the door locations. A350 and 380 have a warning horn in addition to the flashing warning lights at the door, if residual cabin pressure is sensed past a preset point in the event a pressurization outflow valve didn’t fully open.
These warning lights are placed in the sill of the door window, so they can be seen by both FAs in the cabin as well as either jetway ground personnel, or crash rescue personnel.
