(2)
A cross-aisle which leads to the immediate vicinity of each passageway bet-ween the nearest main aisle and aTypeI,TypeII, orTypeIII exit; except that when two Type III exits are located within three passenger rows of each other, a single cross-aisle may be used if it leads to the vicinity between the passageways from the nearest main aisle to each exit.
(b)
[Adequate space to allow crewmember(s) to assist in the evacuation of passengers must be provided as follows :
(1)
The assist space must not reduce the unobstructed width of the passageway below that required for the exit.
(2)

The width of the passagewaymust be measured with adjacent seats adjusted to their most adverse position. The centerline of the required passageway width must not be displaced more than 5 inches horizontally from that of the exit.
(ii)
In lieu of one 10-or 20-inch passageway, there may be two passageways, between seat rows only, that must be at least 6 inches in width and lead to an unobstructed space adjacent to each exit. (Adjacent exits must not share a common passageway.) The width of the passageways must be measured with adjacent seats adjusted totheir most adverseposition. The unobstructed space adjacent to the exit must extend vertically from the .oortotheceiling(orbottomof sidewall stowagebins),inboardfrom the exitfor adistance notlessthanthe width of the narrowestpassenger seat installed on the airplane, and from the forward edge of the forward passageway to the aft edge of the aft passageway. The exit opening must be totally within the fore and aft bounds of the unobstructed space.
