773 (and other 77x) air conditioning
 

Hello,

I would be curious to know if, from the design point of view, there is any significant difference between the 773/77x cabin temperature control and that of other aircraft... which could explain a significant gradient across the Y cabin (namely, too warm close to the overwing exit). In general, I would be curious to learn about the subtleties of cabin environment design and control.

Thank you
