14 CFR Ch. I (1–1–19 Edition) 

§ 29.811 

during the interval between the time 
the exit opening means is actuated 
from inside the rotorcraft and the time 
the exit is fully opened. However, each 
passenger emergency exit which is also 
a passenger entrance door or a service 
door must be provided with means to 
prevent deployment of the slide when 
the exit is opened from either the in-
side or the outside under non-
emergency conditions for normal use. 

(2) It must be automatically erected 

within 10 seconds after deployment is 
begun. 

(3) It must be of such length after full 

deployment that the lower end is self- 
supporting on the ground and provides 
safe evacuation of occupants to the 
ground after collapse of one or more 
legs or part of the landing gear. 

(4) It must have the capability, in 25- 

knot winds directed from the most 
critical angle, to deploy and, with the 
assistance of only one person, to re-
main usable after full deployment to 
evacuate occupants safely to the 
ground. 

(5) Each slide installation must be 

qualified by five consecutive deploy-
ment and inflation tests conducted (per 
exit) without failure, and at least three 
tests of each such five-test series must 
be conducted using a single representa-
tive sample of the device. The sample 
devices must be deployed and inflated 
by the system’s primary means after 
being subjected to the inertia forces 
specified in § 29.561(b). If any part of the 
system fails or does not function prop-
erly during the required tests, the 
cause of the failure or malfunction 
must be corrected by positive means 
and after that, the full series of five 
consecutive deployment and inflation 
tests must be conducted without fail-
ure. 

(h) For rotorcraft having 30 or fewer 

passenger seats and having an exit 
threshold more than 6 feet above the 
ground, a rope or other assist means 
may be used in place of the slide speci-
fied in paragraph (f) of this section, 
provided an evacuation demonstration 
is accomplished as prescribed in 
§ 29.803(d) or (e). 

(i) If a rope, with its attachment, is 

used for compliance with paragraph (f), 
(g), or (h) of this section, it must— 

(1) Withstand a 400-pound static load; 

and 

(2) Attach to the fuselage structure 

at or above the top of the emergency 
exit opening, or at another approved 
location if the stowed rope would re-
duce the pilot’s view in flight.

§ 29.811

Emergency exit marking. 

(a) Each passenger emergency exit, 

its means of access, and its means of 
opening must be conspicuously marked 
for the guidance of occupants using the 
exits in daylight or in the dark. Such 
markings must be designed to remain 
visible for rotorcraft equipped for 
overwater flights if the rotorcraft is 
capsized and the cabin is submerged. 

(b) The identity and location of each 

passenger emergency exit must be rec-
ognizable from a distance equal to the 
width of the cabin. 

(c) The location of each passenger 

emergency exit must be indicated by a 
sign visible to occupants approaching 
along the main passenger aisle. There 
must be a locating sign— 

(1) Next to or above the aisle near 

each floor emergency exit, except that 
one sign may serve two exits if both ex-
ists can be seen readily from that sign; 
and 

(2) On each bulkhead or divider that 

prevents fore and aft vision along the 
passenger cabin, to indicate emergency 
exits beyond and obscured by it, except 
that if this is not possible the sign may 
be placed at another appropriate loca-
tion. 

(d) Each passenger emergency exit 

marking and each locating sign must 
have white letters 1 inch high on a red 
background 2 inches high, be self or 
electrically illuminated, and have a 
minimum luminescence (brightness) of 
at least 160 microlamberts. The colors 
may be reversed if this will increase 
the emergency illumination of the pas-
senger compartment. 

(e) The location of each passenger 

emergency exit operating handle and 
instructions for opening must be 
shown— 

(1) For each emergency exit, by a 

marking on or near the exit that is
