Section 29.811

14 CFR Ch. I (1-1-19 Edition)

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 inside or the outside under nonemergency 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 selfsupporting 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 25knot winds directed from the most
critical angle, to deploy and, with the
assistance of only one person, to remain usable after full deployment to
evacuate occupants safely to the
ground.
(5) Each slide installation must be
qualified by five consecutive deployment 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 representative 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 Section 29.561(b). If any part of the
system fails or does not function properly 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 failure.
(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 specified in paragraph (f) of this section,
provided an evacuation demonstration
is accomplished as prescribed in
Section 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 reduce the pilot-s view in flight.

Section 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 recognizable 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 exists 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 location.
(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 passenger 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
