Federal investigators said that Boeing didn’t make pilots aware that when a plane rapidly depressurizes, the cockpit door will fly open.
Not concerning at all, pilots aren’t important to a plane.
I had thought that since the 2001 hijackings it has been basically impossible to open the cockpit doors during flight, except from the inside. On El Al planes I’d heard it was impossible period, so hijackers couldn’t threaten their way in, but US carriers didn’t want to do that because it means the cockpit needs its own lavatory, displacing a few passenger seats.
In the case of an explosive decompression, you can’t have that wall trying to resist the pressure difference. It’ll blow in a horrible way and probably destroy a ton of circuitry / wiring.
It needs to fail open like this, that design makes sense. The pilots should have been informed though.
An attacker could probably leverage that though to get into the cockpit.
If that design is necessary it has presumably always been like that on every pressurized plane ever built. So it shouldn’t have been a surprise. But, some vents should be able to equalize the pressure without opening the door.
ISTR hearing that El Al planes had separate entrances for the cockpit and passenger compartment so there was no way to enter or leave the cockpit except on the ground. No door, just a reinforced wall. But maybe that was a post-911 urban legend.
Aircraft maintenance has been doing the negative pressure unlock tests on cockpit doors for decades, its honestly surprising what isn’t common knowledge. Like others have said, rapid decompression of only a portion of the aircraft is very bad, and will result in massive structural failure as individual compartments aren’t pressure rated and will blow apart. The doors I’ve had experience with had large panels that would pop out when in a negative pressure event.
Guess that wasn’t good enough
In June, the FAA announced it will require a secondary barrier between the passenger cabin and cockpit of new commercial planes that are manufactured starting in the summer of 2025.
That was at the end of the article. Not sure why but that pisses me off. Probably cause it seems purely like an act based out of fear rathe than in response to any threat/weakness
The problem with locking cockpits is that is that it’s perfect for an evil or very sick pilot.
“I’m not trapped in here with you. You’re trapped in here with ME.”
not like the Boeing 737 Max has had issues before or anything worrisome …
