25.811(e)(4) Emergency exit marking
ED Decision 2017/015/R
The indicating markings for all Type II and larger passenger emergency exit unlocking handle motions should conform to the general shapes and dimensions indicated by Figures 1 and 2.
The indicating markings (arrow and word OPEN) should be consistent with the emergency exit signs chosen, i.e. red if letter emergency exit signs are installed, and green if symbolic emergency exit signs are installed.
NOTE: As far as is practicable the markings should be located to avoid obscuring viewing windows located on or alongside the exits, or coincidence with any other required marking or safety feature.

D = Indicative of the full extent of handle travel (each installation to be individually assessed)
