§ 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

14 CFR Ch. I (1–1–24 Edition) 

§ 25.810 

(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
