Why do the 777 doors open outwards and slide to the side like airbus's instead of like other boeings?

I heard the doors on the B777s are totally different from other Boeings as they open like Airbuses and they can be opened and closed by just one hand.

What's the reason? Is it because it's easier to slide a door open to the side than like on airbus's, instead of opening it like a flap outwards?

Believe me that B777 door can be opened with one finger, its that light to the touch. You have to give that B747 door a good push to open it. Its been a vast improvement to doors on aircraft and maybe Boeing copied it from Airbus?

I was thinking of that too. But the feature you mentioned, wonder if it can be done by one finger on Airbuses' doors? The B777 is not only about technology and a fuel saving gem, it's all about hydraulics! Talk about it's overhead cabins, toilet seats... etc.

One finger or not, it still has a door assist bottle for an emergency. The 777 door is a lot lighter than other Boeing and Airbus double-width doors. The design of the 777 and Airbus doors makes it a lot easier to have commonality throughout the different doors and is a lot lighter than the former.

When Boeing designed the 777 almost everything was re-done...including the doors. The 777 has some of the easiest doors to open and close in the industry. Its sad that the design wasnt applied to the 737NG.

hmmm, i have been working on the 777's and the A330's, not much difference between them except the handle thing. i would say that the a330 doors are lighter than the 777.

If memory serves, a primary reason for the 'translating' door design on the 777 was to make the door interchangeable to any position on each side of the aircraft. In other words, you have single left side or right side doors as opposed to L1, R2 or R4 specific door designs found on most other aircraft.

And commonality? That's good, i always liked the 777, for me it's the perfect commercial aircraft. Everything about it is so great.

Erm...perhaps you didn't understand. You can save weight, production time/cost and oodles of mx issues if the doors on the aircraft are as similar as possible. Take the 747 -- L/R1 is very different from L/R2, despite the same basic design. The 757 -- all of the doors are VERY different. On the 777, the doors are as similar as possible, saving lots of money.

That's what i meant, the economics of the 777 make it a great aircraft.

I don't know why they just didn't adapt the 767 style door to the 777. It has the advantage of not protuding outside the aircraft, so less chance of it being damaged by a catering truck or other ground equipment.

Because it's a lot heavier and needs more mx.

It's alot heavier if you lift it by hand, yes. If you use the switch on the pursers station it's as light as a feather. I can hardly recall seeing a 767 door removed in the 10 years I worked on them, however, I have removed several A320 doors (the one the 777 was modelled on/copied off) for worn hinge parts.

The Boeing 777 door was designed and tested to be opened with a coating of 1/4 inch of ice with minimal hand strength. They wanted to make sure that any FA would be able to open the door even if it had landed in freezing conditions and lots of moisture (like a Chicago ice storm).

"open 777 door with just one hand or one finger?" I don't think so.
777 psgr doors require to be opened with both hands. You put your hands in then the vent door will open first, then you pull the door out and slide it to your left.
However, A330/340 can actually be opened with one hand.

Also, cargo doors can really be opened with just one finger. (pressing a button  Big thumbs up)

I can assure you that the B777 door does not need two hands to open it. While a slight exaggeration on my part that you can open it with one finger it certainly does not need a good shove like the B747. It will take maybe 2 fingers!!!!!! LOL Believe me compared to the B747 the B777 door is much smoother and easier to open. Now if they could just get a bigger window in it so when we sit in our jumpseats we had a bigger view?

Oh yah, I know it takes million tones of horse power to open a 747 door! You have to turn the thing 180 degrees sth. like that.
Myself have never opened a 777 door before. But from the Standard Operation of Psgr Door Guideline, it tells us to open with two hands. Well, maybe really two fingers can do from experienced staff.  Big grin

I can say from personal experience that it takes two hands to extend and rotate the 777 door handle. But, once unlatched, the door can be moved with very little effort. By that same experience I can also say that the 757 door must be moved with a great deal of effort ... much more so then I recall needed for the 747.

No, I mean total weight. The airlines don't care how heavy it is to open. But if it adds 200lbs (1600lbs for all doors) to the aircraft weight, then it's gonna cost the airlines a LOT of money.

The 777 door is MEANT to be opened using one hand in total. One hand is supposed to be used to open the handle, and then in an emergency you fire off the door assist device and let it do its thang.

I was refering to the exterior handle requiring two hands to operate the door. From the inside, yes, it's easily done with one hand.
