B757-200 Door opening

[AcepilotC172]

A lot of the flt atds here in the US are nothing but a bunch of a sky sluts and bad attitudes...FUCKING HATE THEM!!!!

[CBSnews2010]

where was this flight to email me at mroth00@gmail.com

[DeutschFlugbesatzung]

hes blaming the ground staff, even though he should be blaming himself or the flight crew. they shouldve checked that it was onboard

[n310ea]

Are power doors easier to open than manual doors?

[tigersfanatic98]

shes like BITCH im coming in!

[JetMechMA]

757 doors are old fashioned and awkward. A320 doors are VERY easy to use. You can swivel an A320 door with the tip of your finger.

continental airlines???

[northernstudio]

I've always wondered: What if some stupid or drunk passenger thrusted the lever in mid flight?? What would happen realistically?

[Exupery747]

@northernstudio @northernstudio the answer is: nothing at all - the pressure differential will keep the door tightly in place against its frame. Any movement of the handle will illuminate a warning on the flight deck, so the crew will be aware. However, the forces involved in a pressurized cabin ensure that even brute force will not be able to move the door from its closed position.

[yosniffy]

@Exupery747 Yup, I heard (don't quote me haha) that it's as if a person is pushing about 10,000 pounds of pressure against the door.

[JetMechMA]

@yosniffy Well, you can do the arithmetic. The cabin is pressurized to about 8 psi I think. So whatever the square inches of the door is. Say....144 square inches times 8 psi equals about 1,152 pounds exerted on the door. The cabin is actually slightly pressurized before the wheels leave the ground, to about 1.5 psi or so, and this is so wind pressure doesn't blow a door open during the takeoff run. After takeoff the pressure system goes to automatic. At throttle up actually.

@Exupery747 Wait, I thought there was some serious lock on that thing. There isn't?!

[racsito39]

Why door re-opening is a big issue? besides the delay of the flight.

[Exupery747]

@racsito39 no big issue - the purpose of the video is to demonstrate the complex engineering behind the door mechanism: the fact that it was RE-opened is incidental!

[Mindraker1]

@Exupery747 Ah, but this is youtube, where the trivial is extraordinary, and the significant is trivial.

[marklaw]

That FA looks like a bitch!

[Exupery747]

@marklaw well - the attitude was definitely: I'm the jailer and you are the prisoners. I bet she would have performed excellently well in an evacuation though ;)

[irvinmanohar]

@Exupery747 she was assisted by a second person.

[consrignornt]

@marklaw you look like a bitch

[skidrum11]

How does the top and bottom of the door seal?

[Exupery747]

@skidrum11 there are retractable panels about 3 inches in height at the top and bottom of the door exterior that fold inwards to about 45 degrees, which has the effect of shortening the door for opening and closing. When the door closes against its frame, the final movement of the door handle to the closed position operates these panels to close the gaps. you can see the top panel in my other video at 0:06secs 'B757-200 Door Closing'

[skidrum11]

@Exupery747 Thank you much for your clear answer!! I'll take a closer look next time i board...

[Exupery747]

LAX-EWR

[expressmylife]

once the door is opened even if its been closed and re opened we stop getting paid again. and if we never actually left the gate we dont get paid at all.

[mikestamlo]

i like the way the gate agent folder her arms when the flight crew came out lol.

[gazap20]

@mikestamlo keep her jacket closed.... plus it may have been cold

[Exupery747]

It was Continental Airlines.

[crichey1000]

Wow! I have NEVER been on Continental Airlines before!

[Locker10a]

what airline ?
