Hey all,

I have a quick question here. while at SFO i spotted NW 757-300 with 12 exits. (4 over wing, and 8 door exits) that is the first time i encountered such a 757. here is a link to a picture form the data base:

Does this plane have 12 exits b/c its long? even the largest 777's don't have 12 total exits...
thanks for the feedback,
Youngflyer

I was wondering the same thing too. I think all 757-300s are like this. Are all these exits really nessesary? I suppose since the 757 isn't even in production any more, it doesn't matter, but why didn't Boeing scrap the 4 exits over the wing and settle on 8 exits for the 753?

Well if the exits weren't necessary, you can bet Boeing wouldn't have installed them... To answer the question as to why, I believe it has to do with the plane being so long yet only having a single aisle. People would funnel toward the exits and would end up in a standstill due to so many people trying to move in such a small space.

I swear that I (or someone else) started a topic on this years ago, but I can't for the life of me find it.

Anyway, the explanation I was given was simply that the 757 is a single aisle aircraft, and therefore needs more exits.

Whoops, just found it:

http://www.airliners.net/discussions...general_aviation/read.main/1155489

That's my first thread starter on a.net (and my only thread starter in CivAv - guess I learned pretty quick  Wink)

Anyway, Rick767 sums it up succinctly.

Something similar happened when Airbus built the A346. They had to make a new number three door over the wing probably because they couldn't go for the capacity they wanted on the A346 in a standard 8 door configuration. So in a way it's correct, the longer the aircraft becomes, the more doors might have to be installed for safety reasons.

Also, the doors on narrow body aircraft are narrower, allowing only one person to exit at a time, than wide body aircraft, which have doors that can allow two people to exit at the same time.

Also, from what I remember, the 757-200 has 10 exits. I remember seeing that once on a safety video on a DL flight.

Some 752s have 10 (6 doors, 4 overwing exits) and some have 8 (8 doors, no overwing).

They all have the same door configuration if I'm not wrong. It's the 752 which has two configurations.

Assuming this A/C has the same number of exits on the other side, it's got 12 exits. Is this because ATA had their 757s in high density config and had to modify them, just like easyjet had to do with their A319?
thanks
Dominic

Edit: sorry i thought the thread starter said 8 exits

No, because the 753 has the same door configuration on all aircraft. Compare the TZ 753 you linked with a CO 753 (and this being a true CO bird, not one of the ex TZ aircraft they took up):

The same if you compare 753s from FI, DE and NW:

Those are pretty much all operators of the 757-300.

The stretch 8 (61/63 had 12 exits as well...the world's longest airliner until the 747 entered service.

It was also the longest and largest narrowbody ever until the 753 was built.
