Boeing Doors

Thu Nov 15, 2001 4:08 pm

I was wondering,

Why does boeing have different door designs on its aircrafts?
707, 727, 737 and the 747 had the same door design, but starting from the 757, the designs started to differ, for instance the 767 has electrical doors that opens into the fuselage upward, while the 777's has airbus style doors that are pushed up wards.

On the other hand Airbus doors regardless the type of the aircraft or the size of the door and whether it was an Emergency exit or a regular door, the doors are almost the same except for the over wing hatches.

Any body can think of reasons?

Are you sure about the 777? I thought they actually tilt inwards before sliding out sideways just like Concorde's doors. The reasons are unbeknowest to me.

However do ya notice that from their first jet, 707, to their first widebody, 747, the dimensions of the entry doors changed, that I don't get. I think now it's like 1 x 2 meters exactly.

The 777 is unique in large a/c design in that all the doors are exactly the same. This was a major requirement of the design brief as doors are extremely expensive pieces of equipment to design and manufacture. The fuselage had to be designed to be able to accommodate one type of door, regardless of it's position in the fuselage.

I might be wrong, but I always thought that (at least for the 767) it is the airline's choice if they want the door to be opened "into the fuselage upward" or "airbus style". I remember, before I had to do my first ramp job for Delta Air Lines, I had to watch a 10 minutes video illustrating how to open the door of a 767. And I think they mentioned something about a difference between DL's main fleet doors and the Ex-Gulf Air doors. But I have to confess that I really can't remember what was the exact difference (but I'm sure it's not only the number of full size doors/emergency doors that vary). Anyway, I never became ramp agent for DL, they decided to send me to the Qualiflyer check-in instead.

I am sure about the 777 doors, because the airbus doors open the same way. I am sure because I am a flight attendant and I work on Airbus and the boeing 777's  Smile

Door dimensions changed on the 747, because unlike the previous models, the 747 was the first aircraft required to install double-lane evacuation slides. Technically, the door is supposed to handle 2 people leaving it at the same time and jump into the slide channels. 707 up to 737 doors can only take 1 pax leaving at a time.
Rule of thumb-wide body aircraft have double lane slides-single aisle jets smaller doors, hence smaller slides.

Thanx y'all.

Maybe the A380 needs doors as wide as a garage door since it has got 4 aisles?  Smile/happy/getting dizzy

the ex-GULF AIR 767-300s that DL now operates actually have an extra mid-cabin door (not overwing exit) so that would explain the video difference

the regular DL 767-300's are of a configuration that has 2 overwing exits

In comparison of 747 and airbus, I like the airbus door more. The door on airbus is easier and takes less time to open. 747 doors are also heavier than airbus's. This makes it harder for slim female ramp agents to open the door.
