MD-80 2-3 Vs 3-2 Seating

Sun Apr 25, 2004 12:22 pm

Hi all, I was recently looking at an MD-80 cabin picture and noticed the seating arrangement in coach was 3-2, compared to 2-3 from what I am familar with.

I am wondering if there is a certain (or practical) reason for doing this.

Thanks.

I know DLs MD-88s are 3-2 and their MD-90s are 2-3.

AA has a 2-3 config. I really can't say that a 2-3/3-2 would really make a diff. other than the letter for each seat....

I believe it has to do with the positioning of the galleys on the aircraft. If the galley is on the rear left side of the a/c, the 2 abreast seating is on that side. If the galley is on the right rear, then the 2 side is on the right. I could be wrong though...

Having sat in the back of an AA MD-80, I think I know.

If the seating is 2-3, then the rear galley is actually 2 narrow galleys, one aft of the other. If you look, you will see one galley that has the service door. Then, there is a wall the separates the second galley. It has one window.

If the seating is 3-2, then one galley, that is about the same width as those used on Boeing narrowbodies, is installed. This leaves room for two rows of seats on the port side between the galley and the port lav.

Since 2-3 has been the traditional arrangement for Douglas and Fokker aircraft, this is probably the standard seating arrangement, while 3-2 is optional.

Theoretically, the service door can't be on the starboard side, because the aft cargo hatch is on the starboard side.

Are there any weight/balance issues on these planes? I mean it seems like it could pose a problem. Do the pilots just trim for it?

Emorypilot, some enterprising guy in Tech Ops figured out that the 2-3 config moves the center of gravity off the centerline by less than an inch. Not much to worry about in other words.

If you think about it, it's so close to centerline that the moment arm becomes insignificant.

Continental MD-80s have a standard galley layout on the 2 seat port side of the aircraft, with two galley units on either side of the service door. This galley is not as wide as its counterpart at the 1R service door, but is large enough for cart storage, refrigerators, ovens, and all the usual appointments.

Yeah, it has to do with which galleys the airline ordered. The optional, larger galleys would throw everything off, so the seats are switched.
