§ 25.809
(h)
Other exits. The following exits
also must meet the applicable emer-
gency exit requirements of §§ 25.809
through 25.812, and must be readily ac-
cessible:
(1) Each emergency exit in the pas-
senger compartment in excess of the
minimum number of required emer-
gency exits.
(2) Any other floor-level door or exit
that is accessible from the passenger
compartment and is as large or larger
than a Type II exit, but less than 46
inches wide.
(3) Any other ventral or tail cone
passenger exit.
(i)
Ditching emergency exits for pas-
sengers. Whether or not ditching cer-
tification is requested, ditching emer-
gency exits must be provided in accord-
ance with the following requirements,
unless the emergency exits required by
paragraph (g) of this section already
meet them:
(1) For airplanes that have a pas-
senger seating configuration of nine or
fewer seats, excluding pilot seats, one
exit above the waterline in each side of
the airplane, meeting at least the di-
mensions of a Type IV exit.
(2) For airplanes that have a pas-
senger seating configuration of 10 of
more seats, excluding pilot seats, one
exit above the waterline in a side of the
airplane, meeting at least the dimen-
sions of a Type III exit for each unit (or
part of a unit) of 35 passenger seats,
but no less than two such exits in the
passenger cabin, with one on each side
of the airplane. The passenger seat/
exit ratio may be increased through
the use of larger exits, or other means,
provided it is shown that the evacu-
ation capability during ditching has
been improved accordingly.
(3) If it is impractical to locate side
exits above the waterline, the side
exits must be replaced by an equal
number of readily accessible overhead
hatches of not less than the dimensions
of a Type III exit, except that for air-
planes with a passenger configuration
of 35 or fewer seats, excluding pilot
seats, the two required Type III side
exits need be replaced by only one
overhead hatch.
(j)
Flightcrew emergency exits. For air-
planes in which the proximity of pas-
senger emergency exits to the
flightcrew area does not offer a conven-
ient and readily accessible means of
evacuation of the flightcrew, and for
all airplanes having a passenger seat-
ing capacity greater than 20, flightcrew
exits shall be located in the flightcrew
area. Such exits shall be of sufficient
size and so located as to permit rapid
evacuation by the crew. One exit shall
be provided on each side of the air-
plane; or, alternatively, a top hatch
shall be provided. Each exit must en-
compass an unobstructed rectangular
opening of at least 19 by 20 inches un-
less satisfactory exit utility can be
demonstrated by a typical crew-
member.

§ 25.809
Emergency exit arrangement.
(a) Each emergency exit, including
each flightcrew emergency exit, must
be a moveable door or hatch in the ex-
ternal walls of the fuselage, allowing
an unobstructed opening to the out-
side. In addition, each emergency exit
must have means to permit viewing of
the conditions outside the exit when
the exit is closed. The viewing means
may be on or adjacent to the exit pro-
vided no obstructions exist between the
exit and the viewing means. Means
must also be provided to permit view-
ing of the likely areas of evacuee
ground contact. The likely areas of
evacuee ground contact must be
viewable during all lighting conditions
with the landing gear extended as well
as in all conditions of landing gear col-
lapse.
(b) Each emergency exit must be
openable from the inside and the out-
side except that sliding window emer-
gency exits in the flight crew area need
not be openable from the outside if
other approved exits are convenient
and readily accessible to the flight
crew area. Each emergency exit must
be capable of being opened, when there
is no fuselage deformation—
(1) With the airplane in the normal
ground attitude and in each of the atti-
tudes corresponding to collapse of one
or more legs of the landing gear; and

(2) Within 10 seconds measured from
the time when the opening means is ac-
tuated to the time when the exit is
fully opened.
(3) Even though persons may be
crowded against the door on the inside
of the airplane.
(c) The means of opening emergency
exits must be simple and obvious; may
not require exceptional effort; and
must be arranged and marked so that
it can be readily located and operated,
even in darkness. Internal exit-opening
means involving sequence operations
(such as operation of two handles or
latches, or the release of safety
catches) may be used for flightcrew
emergency exits if it can be reasonably
established that these means are sim-
ple and obvious to crewmembers
trained in their use.
(d) If a single power-boost or single
power-operated system is the primary
system for operating more than one
exit in an emergency, each exit must
be capable of meeting the requirements
of paragraph (b) of this section in the
event of failure of the primary system.
Manual operation of the exit (after
failure of the primary system) is ac-
ceptable.
(e) Each emergency exit must be
shown by tests, or by a combination of
analysis and tests, to meet the require-
ments of paragraphs (b) and (c) of this
section.
(f) Each door must be located where
persons using them will not be endan-
gered by the propellers when appro-
priate operating procedures are used.
(g) There must be provisions to mini-
mize the probability of jamming of the
emergency exits resulting from fuse-
lage deformation in a minor crash
landing.
(h) When required by the operating
rules for any large passenger-carrying
turbojet-powered airplane, each ven-
tral exit and tailcone exit must be—
(1) Designed and constructed so that
it cannot be opened during flight; and
(2) Marked with a placard readable
from a distance of 30 inches and in-
stalled at a conspicuous location near
the means of opening the exit, stating
that the exit has been designed and
constructed so that it cannot be opened
during flight.
(i) Each emergency exit must have a
means to retain the exit in the open
position, once the exit is opened in an
emergency. The means must not re-
quire separate action to engage when
the exit is opened, and must require
positive action to disengage.

§ 25.810
Emergency egress assist
means and escape routes.
(a) Each non over-wing Type A, Type
B or Type C exit, and any other non
over-wing landplane emergency exit
more than 6 feet from the ground with
the airplane on the ground and the
landing gear extended, must have an
approved means to assist the occupants
in descending to the ground.
(1) The assisting means for each pas-
senger emergency exit must be a self-
supporting slide or equivalent; and, in
the case of Type A or Type B exits, it
must be capable of carrying simulta-
neously two parallel lines of evacuees.
In addition, the assisting means must
be designed to meet the following re-
quirements—
(i) It must be automatically deployed
and deployment must begin during the
interval between the time the exit
opening means is actuated from inside
the airplane and the time the exit is
fully opened. However, each passenger
emergency exit which is also a pas-
senger entrance door or a service door
must be provided with means to pre-
vent deployment of the assisting means
when it is opened from either the in-
side or the outside under non-
emergency conditions for normal use.
(ii) Except for assisting means in-
stalled at Type C exits, it must be
automatically erected within 6 seconds
after deployment is begun. Assisting
means installed at Type C exits must
be automatically erected within 10 sec-
onds from the time the opening means
of the exit is actuated.
(iii) It must be of such length after
full deployment that the lower end is
