CS 27.805 Flight crew emergency exits ED Decision 2018/007/R (a) For rotorcraft with passenger emergency exits that are not convenient to the flight crew, there must be flight crew emergency exits, on both sides of the rotorcraft or as a top hatch, in the flight crew area. (b) Each flight crew emergency exit must be of sufficient size and must be located so as to allow rapid evacuation of the flight crew and must be marked so as to be readily located and operated even in darkness. This must be shown by test. (c) Underwater emergency exits for flight crew. If certification with ditching provisions is requested by the applicant, none of the flight crew emergency exits required by (a) and (b) may be obstructed by water or flotation devices after an emergency landing on water and each exit must shown by test, demonstration, or analysis to provide for rapid escape with the rotorcraft in the upright floating position or capsized. Each operational device (pull tab(s), operating handle, ‘push here’ decal, etc.) must be marked with black and yellow stripes and must be shown to be accessible for the range of flight crew heights as required by [CS 27.777(b)](#_DxCrossRefBm8893933) and for both the case of an un-deformed seat and a seat with any deformation resulting from the test conditions required by [CS 27.562](#_DxCrossRefBm8893829). Flight crew emergency exits must be reasonably protected from becoming jammed as a result of fuselage deformation. The markings required by (b) must remain visible if the rotorcraft is capsized and the cabin is submerged.
