14 CFR Ch. I (1–1–19 Edition) 

§ 25.811 

(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) Means must be provided to assist 

the occupants in locating the exits in 
conditions of dense smoke. 

(d) The location of each passenger 

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

(1) A passenger emergency exit loca-

tor sign above the aisle (or aisles) near 
each passenger emergency exit, or at 
another overhead location if it is more 
practical because of low headroom, ex-
cept that one sign may serve more 
than one exit if each exit can be seen 
readily from the sign; 

(2) A passenger emergency exit mark-

ing sign next to each passenger emer-
gency exit, except that one sign may 
serve two such exits if they both can be 
seen readily from the sign; and 

(3) A sign on each bulkhead or divider 

that prevents fore and aft vision along 
the passenger cabin to indicate emer-
gency exits beyond and obscured by the 
bulkhead or divider, except that if this 
is not possible the sign may be placed 
at another appropriate location. 

(e) The location of the operating han-

dle and instructions for opening exits 
from the inside of the airplane must be 
shown in the following manner: 

(1) Each passenger emergency exit 

must have, on or near the exit, a mark-
ing that is readable from a distance of 
30 inches. 

(2) Each Type A, Type B, Type C or 

Type I passenger emergency exit oper-
ating handle must— 

(i) Be self-illuminated with an initial 

brightness of at least 160 micro-
lamberts; or 

(ii) Be conspicuously located and well 

illuminated by the emergency lighting 
even in conditions of occupant crowd-
ing at the exit. 

(3) [Reserved] 
(4) Each Type A, Type B, Type C, 

Type I, or Type II passenger emergency 
exit with a locking mechanism re-
leased by rotary motion of the handle 
must be marked— 

(i) With a red arrow, with a shaft at 

least three-fourths of an inch wide and 
a head twice the width of the shaft, ex-

tending along at least 70 degrees of arc 
at a radius approximately equal to 
three-fourths of the handle length. 

(ii) So that the centerline of the exit 

handle is within 

±

1 inch of the pro-

jected point of the arrow when the han-
dle has reached full travel and has re-
leased the locking mechanism, and 

(iii) With the word ‘‘open’’ in red let-

ters 1 inch high, placed horizontally 
near the head of the arrow. 

(f) Each emergency exit that is re-

quired to be openable from the outside, 
and its means of opening, must be 
marked on the outside of the airplane. 
In addition, the following apply: 

(1) The outside marking for each pas-

senger emergency exit in the side of 
the fuselage must include a 2-inch col-
ored band outlining the exit. 

(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. 

(3) In the case of exists other than 

those in the side of the fuselage, such 
as ventral or tailcone exists, the exter-
nal means of opening, including in-
structions if applicable, must be con-
spicuously marked in red, or bright 
chrome yellow if the background color 
is such that red is inconspicuous. When 
the opening means is located on only 
one side of the fuselage, a conspicuous 
marking to that effect must be pro-
vided on the other side. 

(g) Each sign required by paragraph 

(d) of this section may use the word 
‘‘exit’’ in its legend in place of the 
term ‘‘emergency exit’’.
