May 26, 20233 yr Airbus A321-200, Korea. Everyone is aware of this incident today by now. The questions are: How can this be prevented and still allow ordinary passengers a quick way escape after a crash? Why wasn't he restrained? The answer here is that it was on landing, 700 feet high and the crew was busy. Why did he do this? Nobody knows, but these decades, many of us probably suspect drugs. https://www.fox5ny.com/news/passenger-opens-plane-door-flight-south-korea 5800X3D, RTX4070, 600 Watt, one or two 1440p 32" screens, 64 GB RAM, 4 TB PCle 3 NVMe, Warthog throttle, VKB NXT EVO stick, Honeycomb Alpha yoke, CH quad, 3 Logitech panels, 2 StreamDecks, Desktop Aviator Trim Panel.

May 27, 20233 yr Interesting, when I flew the DC10, once the throttles are advanced for takeoff, the pressurization did a pre charge and drove the cabin below current pressure. It did the same on landing. After touch down, the cabin would raise to current outside pressure. This precharge was enough to keep the doors from opening in flight as the door didn't have enough opening force to overcome the differential against the door. The doors were plug type and actually came in some inches before it raised to the open position. It could also work against you on the ground in an emergency. There was a max diff for landing that ensured you could get the door open if the pressure didn't automatically bleed off. When the thrust recovery valve opened at touch down.

May 27, 20233 yr 1 hour ago, G550flyer said: After touch down, the cabin would raise to current outside pressure. Very interesting indeed. As you mentioned after touchdown relief valves will open and will equalize cabin pressure with the outside. I am confused about the video because it seems like the door is fully open at a 90-degree angle, but also I don't understand why the outside view is not moving. The other two issues I have is one that the A321 doors don't open outward, actually, they pop out a few inches and then they slide alongside the fuselage. Another important point is that the aircraft doors cannot be opened when the cabin is pressurized, particularly for this Airbus the approach speed range is between 130 to 155 KTS Vref. It is virtually impossible for anyone to open the door in these conditions. However, additional information is required as the current statement is not entirely accurate. 747 Captain for the last 39 years, and still learning.
May 27, 20233 yr Author Oh wow. Now the opposite, also today. In San Diego, a passenger exited the plane after landing and locked the door! https://www.fox5ny.com/news/photos-capture-southwest-pilot-climbing-through-cockpit-window-to-unlock-plane-door 5800X3D, RTX4070, 600 Watt, one or two 1440p 32" screens, 64 GB RAM, 4 TB PCle 3 NVMe, Warthog throttle, VKB NXT EVO stick, Honeycomb Alpha yoke, CH quad, 3 Logitech panels, 2 StreamDecks, Desktop Aviator Trim Panel.
