14 CFR Ch. I (1–1–14 Edition)
§ 25.812
(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’’.

§ 25.812
Emergency lighting.
(a) An emergency lighting system,
independent of the main lighting sys-
tem, must be installed. However, the
sources of general cabin illumination
may be common to both the emergency
and the main lighting systems if the
power supply to the emergency light-
ing system is independent of the power
supply to the main lighting system.
The emergency lighting system must
include:
(1) Illuminated emergency exit mark-
ing and locating signs, sources of gen-
eral cabin illumination, interior light-
ing in emergency exit areas, and floor
proximity escape path marking.
(2) Exterior emergency lighting.
(b) Emergency exit signs—
(1) For airplanes that have a pas-
senger seating configuration, excluding
pilot seats, of 10 seats or more must
meet the following requirements:
(i) Each passenger emergency exit lo-
cator sign required by § 25.811(d)(1) and
