B767-300 Door Layout

Can anyone explain to me the logic behind the door layout on 763’s?

I’m really confused, there seems to be no standard. Obviously they’ve all got full size doors at front and rear (we’ll call these Doors 1 and 4 for this excercise!). Some have one overwing hatch (the chuck out kind), some have two overwing hatches, some have one overwing hatch and then a proper Doors 3, some have proper Doors 2 and 3 and no hatches at all! Whats it all about???

I presume its something to do with airline customer preference, seating capacity etc. Surely this make them harder to remarket if their next owner wants to increase the seating capacity but they can’t because of how many doors it has?

Hope someone has the technical explanation here as this really bugs me! lol!

Cheers!

talking of First Choice G-OOAN and AL have the 3 door config all being large doors. They are keeping OOAN as they refurbish, however the new ones they are getting from Vietnam, have 2 front, 1 overwing small door and 1 large back door, so this means they are going to have to produce 2 types of safety card, which is a bit of a hassle.

We always had amendments in our manuals back in the AMM days topjet. AMM had a very mixed fleet of 757’s then. Some with toilets 2 forward and two mid, some with 1 forward and 3 mid, and thats just the loo’s! The safety equipment was in a different place on every aircraft, and this all had to be documented in the crew SOP manuals. Some had life rafts for ETOP’s, some not.

All I can say is… the training courses were an absolute nightmare! I think a few different safety cards is the least of their worries. Think of the poor crew with all their different sections in their manuals for each aircraft 😮

Bmused55,

You’ve explained the 3 door options on the 767-300 well but I think you’re quote in option 3) “This allows for maximum pax density. This config is popular with, though not limited to, charter carriers.” is incorrect imo. Surely for a maximum seating density you need the greatest number off large exit doors as detailed in option 1?? If you look at Britannia, First Choice and Mytravel, they operate the most dense configuration anywhere and all their a/c have option 1.(4 large doors)

Less doors mean less wasted open space around the doors.

My comments were not meant to be 100% factual, just as a guide,

The missing door at the rear allows for as much as 2 or 3 full sized rows extra as opposed to the 4 door version

Cheers Sandy.

It just amazes me how you can possibly evacuate a high density 763 with all those people trying to jump out tiny overwing hatches.

I think I prefer the 757, at least your never more than 10 rows from a proper exit if your on the 4 doors option.

I’ve never been able to figure it out either.
But the 2 door variant of the 763 is popular and appears to have no adverse effects.

The way I see it, 9 times out of 10 if you need to get out in such a hurry, its already too late :rolleyes:

Yes, I used to work on the 757, but obviously, most British airlines don’t have the overwings hatches on there models. In fact, I don’t think I know of any with overwings?

Well that clarify’s the 767 question anyway, I wondered for ages if it was something to do with the age etc!

Thanks for your reply.

The 757 does have an over wing configuration. I believe these generally have a higher MTOW.

Contintental, Icelandair, Finnair are but a few who use them.

For the 757-300, both door configurations are mixed together. There is no option for the 300. 1L, 2L, Hatch, Hatch, 3L, 4L

There are 3 configurations for the 763, depending on customer spec.
Here are the configurations available, with pics to illustrate:

1) Configuration 1 has 2 doors forward of the wing and 2 doors Aft of the wing. The one immediately behind the wing is a smaller, emergency exit. This configuration typically affords maximum privacy for Biz or First class pax during boarding. Popular with mainstream airlines.

2) Similar to config 1, but the door immediately behind the wing is taken away, in stead you have a single overwing escape hatch. This typically allows for more economy class seats while still maintaining max privacy for First and Biz Class.
http://www.airliners.net/open.file/636790/L/

3) The most space saving configuration, It has just 1 main door forward of the wing, 2 overwing escape hatches and one main door aft of the wing. This allows for maximum pax density. But First and Biz Pax have less privacy on boarding as everyone must trail through the forward cabin. This config is popular with, though not limited to, charter carriers.

You’re absolutely right ABBaby it’s about customer preference. Airlines will chose what they have depending on the number of seats and layout they intend to have onboard.

The 757 was also available with similar options of 2/3 doors or hatches.

1L.
