Federal Aviation Administration, DOT 

§ 29.811 

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 
readable from a distance of 30 inches; 
and 

(2) For each Type I or Type II emer-

gency exit with a locking mechanism 
released by rotary motion of the han-
dle, by— 

(i) A red arrow, with a shaft at least 

three-fourths inch wide and a head 
twice the width of the shaft, extending 
along at least 70 degrees of arc at a ra-
dius approximately equal to three- 
fourths of the handle length; and 

(ii) The word ‘‘open’’ in red letters 1 

inch high, placed horizontally near the 
head of the arrow. 

(f) Each emergency exit, and its 

means of opening, must be marked on 
the outside of the rotorcraft. In addi-
tion, the following apply:

14 CFR Ch. I (1–1–24 Edition) 

§ 29.812 

(1) There must be a 2-inch colored 

band outlining each passenger emer-
gency exit, except small rotorcraft 
with a maximum weight of 12,500 
pounds or less may have a 2-inch col-
ored band outlining each exit release 
lever or device of passenger emergency 
exits which are normally used doors. 

(2) Each outside marking, including 

the band, must have color contrast to 
be readily distinguishable from the sur-
rounding fuselage surface. The contrast 
must be such that, if the reflectance of 
the darker color is 15 percent or less, 
the reflectance of the lighter color 
must be at least 45 percent. ‘‘Reflec-
tance’’ is the ratio of the luminous flux 
reflected by a body to the luminous 
flux it receives. When the reflectance 
of the darker color is greater than 15 
percent, at least a 30 percent difference 
between its reflectance and the reflec-
tance of the lighter color must be pro-
vided. 

(g) Exits marked as such, though in 

excess of the required number of exits, 
must meet the requirements for emer-
gency exits of the particular type. 
Emergency exits need only be marked 
with the word ‘‘Exit.’’

amended by Amdt. 29–24, 49 FR 44438, Nov. 6,

§ 29.812

Emergency lighting. 

For transport Category A rotorcraft, 

the following apply: 

(a) A source of light with its power 

supply independent of the main light-
ing system must be installed to— 

(1) Illuminate each passenger emer-

gency exit marking and locating sign; 
and 

(2) Provide enough general lighting 

in the passenger cabin so that the aver-
age illumination, when measured at 40- 
inch intervals at seat armrest height 
on the center line of the main pas-
senger aisle, is at least 0.05 foot-candle. 

(b) Exterior emergency lighting must 

be provided at each emergency exit. 
The illumination may not be less than 
0.05 foot-candle (measured normal to 
the direction of incident light) for min-
imum width on the ground surface, 
with landing gear extended, equal to 
the width of the emergency exit where 
an evacuee is likely to make first con-

tact with the ground outside the cabin. 
The exterior emergency lighting may 
be provided by either interior or exte-
rior sources with light intensity meas-
urements made with the emergency 
exits open. 

(c) Each light required by paragraph 

(a) or (b) of this section must be oper-
able manually from the cockpit station 
and from a point in the passenger com-
partment that is readily accessible. 
The cockpit control device must have 
an ‘‘on,’’ ‘‘off,’’ and ‘‘armed’’ position 
so that when turned on at the cockpit 
or passenger compartment station or 
when armed at the cockpit station, the 
emergency lights will either illuminate 
or remain illuminated upon interrup-
tion of the rotorcraft’s normal electric 
power. 

(d) Any means required to assist the 

occupants in descending to the ground 
must be illuminated so that the erect-
ed assist means is visible from the 
rotorcraft. 

(1) The assist means must be pro-

vided with an illumination of not less 
than 0.03 foot-candle (measured normal 
to the direction of the incident light) 
at the ground end of the erected assist 
means where an evacuee using the es-
tablished escape route would normally 
make first contact with the ground, 
with the rotorcraft in each of the atti-
tudes corresponding to the collapse of 
one or more legs of the landing gear. 

(2) If the emergency lighting sub-

system illuminating the assist means 
is independent of the rotorcraft’s main 
emergency lighting system, it— 

(i) Must automatically be activated 

when the assist means is erected; 

(ii) Must provide the illumination re-

quired by paragraph (d)(1); and 

(iii) May not be adversely affected by 

stowage. 

(e) The energy supply to each emer-

gency lighting unit must provide the 
required level of illumination for at 
least 10 minutes at the critical ambient 
conditions after an emergency landing. 

(f) If storage batteries are used as the 

energy supply for the emergency light-
ing system, they may be recharged 
from the rotorcraft’s main electrical 
power system provided the charging
