The Boeing doors are safer though, since they open inside out, they have the whole pressure of the cabin pushing it to a close position. From what I remember Airbus doors open outside out, putting a constant pressure on the door when the A/C is pressurised. But yes the Boeing doors on the 737 are a bit archaic in the way they operate, but since everything is manual it adds safety as well.
Most pressurised airliners have doors that are held closed by the internal pressure, and are impossible to open in flight. It's not so clear that's true with this door.
@@sammy2745 I say yes as I am agreeing that it is more complicated compared to the 320. I say it is safer as if the door was not closed completely and there was an opened seal, the chances of something going wrong is higher on the 320 than 737.
In an Airbus there is an ARMING indicator. Armed it will deploy the slide. There is also a pressure sensor, a locked/unlocked indicator and the door has to be pushed out then slid sideways so Air Pressure can't explode it outwards.
google ;I am having hell of time understanding the cargo doors of the E 190 . I don't understanding the handle system but flush is easy . I have opened many aircraft doors as an aircraft cargo loader but the E 190 cargo doors have been the hardest I have experienced .
Plug doors. A simple and elegant concept that adds redundancy by it's very nature. The door is too big to fit through the opening so it has to be pushed in and turned first.
Yay! it's awesome! What i quite don't understand is how Airbus doors keep airtight because the door *should* be the same size as its hole and that means the locking rigs/pins take all the force as of the Boeing 737 door some force is taken off the pins/rigs and into the door frame as the Boeing 737 door is bigger than its hole.
Samuel Karlsson yes but the airbus door expands upwards and downwards when the handle is pulled. Concealed sections of the door are inside the door when it’s opened, and when it’s shut they come down and up outwards from each edge of the door up and down and lock into place.
Bad opening and closing cabin door system, the best system was a heritage from the magnificient and unforgetable Lockheed L1011 Tristar....DC10-MD11 and B767....
А если мы хотим открыть дверь ВС снаружи и дверь в положении ARMED, то как быть? как понять снаружи, что дверь вооружена и можно ли ее открыть в вооруженном состоянии без выстрела надувного трапа? Зачем двери вентиляция?
При открытии двери снаружи дверь автоматически разоружается. Согласно OM part B 12.25: The escape slide is automatically disarmed when the door is opened from outside. The vent flap opens automatically when the lower part of the external handle is pulled.
pashok1230 ты чё? Чтобы определить вооруженность двери просто глянь на вент. Клапан Открыт-трап разружён Закрыт-трап заружён Если дверь открыть снаружи то надувной трап разружается
i think this is more safer than Airbus's doors.First it opens little to the cabin.This operation guarantee that door cannot be opened in the sky because of pressure differance between cabin and atmosphere.
I'm with ya, this door requires an inboard movement *against* all air pressure difference. An AirBus doordoesn't work like this. It moves upward keeping same air pressure difference force acing on the door. Other "good" doors are on the 707, 727, 747, 757 and 767, 777 has same design as airbus * facepalm * Those are the airplane models(except B777) that i know of which have inboard moving door openings.
