An apparatus and method is disclosed for increasing available space in an
aircraft cabin cross section to improve passenger comfort. Use of one side
wall supported armrest on each side of the aircraft's cross section,
rather then seat supported armrest as are provided conventionally
elsewhere, enables use of wider seats. Side wall supported armrests may be
secured by means of rails or other conventional mounting means, and the
armrests may be contoured an/or cushioned to provide a better ergonomic
arm support. Contoured armrests may also be recessed into the space
between aircraft cabin body frames.
