Best 752/763 Door Configuration?

Mon Sep 10, 2012 5:38 pm

There are a couple of different possible door configurations for the 752 and 763, and I'd like to know what the pros and cons of the different types are, and what would lead carriers to prefer one or the other. If I'm not mistaken, these are the different configurations:
752a: big door ahead of wings, two overwing emergency exits
752b: big door ahead of wings, big door aft of wings (A321 style)

763a: big door ahead of wings, two overwing exits
763b: just two overwing exits
763c: big door forward and behind wing (A330 style)

With the 752, I'd imagine you lose a row in the 752b configuration, but you also have greater spacing for the overwings in 752a. Is this a wash seat count wise, or is there a weight/cost reason to go with one or the other?

On the 763, the twin overwing exits would appear to be the best weight-wise, would the only compelling reason to go with the big doors be if you're planning on putting in more seats (e.g. big Y section, 8 across)?

Lastly, why do the A321 and A330 only have the spaced door configurations? I know the A330 has the option of a 3/4 size door 3, but the positioning is always the same. Could the 321 get away with the 752a style doors (same 321 front door, 320 style overwing), or are the production differences not worth the hassle?

Quoting LH707330 (Thread starter):
763a: big door ahead of wings, two overwing exits
763b: just two overwing exits

By two overwing exits, do you mean two sets, or two total? The "763a" configuration with the doors ahead of the wings has only one set of overwing exits (two total), while the "763b" configuration has two sets of overwing exits (four total).

Also, the 764ER also only has the spaced exits (like the A330). In addition, there are actually two configurations for the 762, either with one or two sets of overwing exits, the latter mostly used by high-density charter airlines due to evacuation requirements.

The 767-300 has 3 different door configurations.

1. 3 double wide doors (2 before the wing, 1 aft) and 1 floor level plug door after the wing
2. 3 double wide doors (2 before the wing, 1 aft) and 1 overwing exit
3. 2 double wide doors (1 before the wing, 1 aft) and 2 overwing exits

The 1st configuration can hold the most pax, but that is because you can go 8 abreast in an all-economy configuration. You can fit more in the 3rd configuration with a 7 abreast economy because you don't lose the space that is needed by the extra doors. HA has all 3 configurations and the 1st configuration seats 252, and the 3rd seats 264. IIRC, the 2nd configuration is 256.
