First off Flight Attendants are quite privy on the operator of every door in the specific fleet. Not all doors are plug style doors, so it amaez me that any of you would sit here and question a crew member. Only 737's and 757's have plug rotating doors, 777's just push out and forward and 767's going in the ceiling and are completely automatic doors. It takes placing your hand on a armed 767's emergency handle and that door will blow like a rocket.
I personally have been on a flight where a passenger attempted to open the door in flight. He was strong enough to begin to rotate the handle and after subdued, we could not get the handle to go back down and had to re-seat pax and remain away from the door. So here is my take on it, you want to look outside and you don't have a window seat? Learn over a your neighbor and look out, but be sure to stay away from my door, no matter how small a risk and impossible it is to open. Those windows are mostly useless unless you are looking for fire,smoke,water, or large debris. ^ Yes..you may know how to operate the doors...but you certainly don't understand anything about how they function. The 767 door does indeed stow up into the overhead but the door itself is still larger than the fuselage cut out and when operating the door it actually travels inward a few inches. It is this inward travel that is prevented by the pressurization. The 777 door does not open outward and then forward...think carefully....it initially travels inboard a few inches when you rotate the handle through about halfway and then starts to swing out. Again, it is this inward travel at the beginning that makes it impossible to open the door inflight. As to the emergency operation of the 767 door I can not speak since I don't have specific knowledge of it but take the 747-400. The main deck doors are all plug-type and operate like the 777. The upper deck doors are not plug type however they have a lock-out mechanisms that engages when the plane senses that it is airborne. This is straight from the Boeing manual: An automatic lock activates in flight to lock the upper deck door operating handles to prevent inadvertent operation. If the upperdeck door automatic lock fails to operate after take-off, the EICAS caution message DOOR U/D FLT LK is displayed and the blue Door Ground Mode Light above the affected door illuminates. In this condition it is possible to open an upper deck door when cabin differential pressure is below 3 PSI. |

Flying back from Europe yesterday. Took an unusually northern route, over Greenland. I come out of the lav, and look out of the window for maybe 15 seconds.
A flight attendant screams at me: "GET AWAY FROM THE DOOR!" Like I was going to do what to it? Smear the window? Carve my initials? Yeesh... |

OP here. I think I described the event fairly.
I was looking out of that window since Greenland was on that side, and my seat on the other. Was midship on a 764, so nowhere near a galley. I do plead guilty to cathering (gathering of one) in a lav area. Incidentally, was my first flight on CO metal as a OP Plat. Maybe it was her way of saying "welcome! We appreciate your business!" |
I remember when flying was fun. Not any more.

I'm flying Saturday, I'll give it a go and report back. Mind you, you might see it on the news first. :D

The upper deck doors are not plug type however they have a lock-out mechanisms that engages when the plane senses that it is airborne. This is straight from the Boeing manual: As for the pax rotating the handle...as was mentioned before..yes someone can rotate it but you still can not open the door. The amount was minimal..only up until the point where the door itself would actually start to move, remember, the first bit of travel by the handle is for the mechanism that disengages the GERT bar. The reason you would have to keep pax away from the door with the handle not stowed in the closed position is to avoid potential harm during descent as the cabin pressure descends as this WOULD allow for the door to open. -The 777 door travels straight up a couple of inches, then out and forward. It does not move into the cabin. Here is a video of the door closing, but you can see what I am referring too: http://www.youtube.com/watch?v=JUqn9bHWoyQ -If moving the handle (the one on the inside) disengaged the girt bar then the slide would not blow. The only thing inside the cabin that disengages the girt bar is the Arm/Disarm lever or on the 737 actually moving the girt bar to/from the brackets. Also the 757, 767, and 777 when opened from the outside will automatically disarm before the door opens. This is why the agents always open the doors upon arrival with these aircraft. |
Also, I just wanted to add that the 777 door has a "hole" in the door covered by a flap that is connected to the handle. The flap moves into the door when the door is opened, and when the plane is pressurized the flap will not move also preventing the handle from moving. You can see what I am referring to in these pictures:

In Soviet Russia door moves you.

I mean, is anyone really surprised that COEWRFA has no idea what he/she is talking about?

I am not going to claim to be an expert on the mechanisms on aircraft doors, but there are 2 mistakes in your post.

Meant to say the GIRT bar is indeed disengaged by the arming mechanism...the little bit of "slack" in the door handle is to slight open the door to check that it actually disengaged. And also correct on 777 door..I was mixing it up with the 747 door.

Physics aside (much of what this thread has addressed), I think the reaction could have been handled a bit better.
Behaviors, appropriate or not, usually have a driver behind them, and there's obviously just as much concern for your safety as their own. We've all seen a flurry of stories where there's the real perception that flight crews have occasionally overreacted to incidents onboard the aircraft, but few careers have seen such a rise in evolving threats. Unfortunately, in this day, we've lost a lot of our ability to enjoy innocent pleasures without raising an eyebrow at 30,000ft. |
No problem dkul... I would hope everyone on here understands jet lag!!
