Why Do They Have Gaps With No Windows?

Tue May 30, 2006 3:50 am

Why is it that on aircraft such as the 757 or 767 they have seats with no windows? Why is it necessary for Boeing to miss a window out?
All feedback welcomed.

Generally this is where the air duct comes up from the packs (below the passenger floor) to the air vents (above the cabin).

I sat next to this on a 744 once. Besides having no view, it was noisy as hell from all the air rushing through the vent. I hate those seats.

As far as I know, all planes have this. Including 737,747,777 and Airbus. I flew BMIbaby a while ago and got the only seat in the house with no window! I was literally p*ssed off and demanded a new seat, so they gave me a overwing exit seat Big grin

The bigger Airbi have it, but in my experience, the A32X do not. Looking at my technical cutaway, the A319 has smaller ducts running up the cabin wall between the windows - I assume the 318, 320 and 321 would be the same way.

Why they have that instead of a bigger one, I'm not sure.

I've run intot this problem on UA's 763s. Seatguru will point out any windowless seat for those that insist on seeing what's out there...

B737-200 had six small ducts on each side of the fuselage, and no missing windows. But when the B737-300 was designed the ducts had to be bigger, so a single large duct was installed instead with a missing window.

US A321s have it. Just sat next to it in row 13 on a recent PHL-PHX flight.

Was this just aft of the Nbr 2 door? All BA A319/320/321 have small air riser ducts between each window to take the incoming air up to the overhead distribution duct. There are no large ducts , and no missing windows for air con purposes.

Correct me if I'm wrong, but Boeing tends to put this "blank" next to the engines on the narrowbody jets with some extra structural reinforcement to add another layer of protection against an uncontained fan blade failure.

I always avoid this seat on the Boeings.

Some times there are lavatories located there too not just in the middle of the aisle.

Often when an airplane is originally ordered, no windows or window cutouts were installed in areas where lavatories and galleys are to be located. Eventually with changes in configurations and/or operators, seats are installed at these locations. The result is a seat row with no window.

767 have conditioned air riser ducting and blank sidewalls forward of door 2 at approximately STA 700 and 740.

Not correct.
As stated in relpy 2, it's for conditioned air ducting.

Most often, there is no sidewall panel behind the lavs and galleys in the delivered configuration. No reason for it and it would just add weight.
