to identify and locate each passenger emergency exit must be recognisable from a distance equal to the width of the cabin.
       26.3 Each passenger emergency exit and access to it must be marked in a way that enables the occupants to locate the exit even if there is dense smoke in the cabin.
       26.4 Each passenger emergency exit must be indicated by locating signs that are visible to occupants approaching along the main passenger aisle or aisles, so that there is a sign:
(a) either:
           (i) above the aisle or aisles near each passenger emergency exit; or
           (ii) if low headroom makes this impracticable — at another overhead location; and
       (b)      next to each passenger emergency exit; and
       (c)      if a bulkhead or divider prevents fore and aft vision along the passenger cabin, either:
           (i) on each such bulkhead or divider, indicating that emergency exits are beyond the bulkhead or divider; or
           (ii) if this is not possible — to the same effect at another appropriate location.
       26.5 For paragraphs 26.4 (a) and (b), 1 sign may serve more than 1 exit if the sign is such that each exit can be easily identified and readily seen because of the sign.
