14 CFR Ch. I (1-1-19 Edition)

(i) Floor level exits. Each floor level door or
exit in the side of the fuselage (other than
those leading into a cargo or baggage compartment that is not accessible from the passenger cabin) that is 44 or more inches high
and 20 or more inches wide, but not wider
than 46 inches, each passenger ventral exit
(except the ventral exits on M-404 and CV-
240 airplanes) and each tail cone exit must
meet the requirements of this section for
floor level emergency exits. However, the
Administrator may grant a deviation from
this paragraph if the Administrator finds
that circumstances make full compliance
impractical and that an acceptable level of
safety has been achieved.
(j) Additional emergency exits. Approved
emergency exits in the passenger compartments that are in excess of the minimum
number of required emergency exits must
meet all of the applicable provisions of this
section except paragraph (f), (1), (2), and (3)
and must be readily accessible.
(k) On each large passenger-carrying turbojet-powered airplane, each ventral 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 installed 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.

APPENDIX B TO PART 125 - CRITERIA FOR
DEMONSTRATION
OF
EMERGENCY
EVACUATION PROCEDURES UNDER
Section 125.189
(a) Aborted takeoff demonstration. (1) The
demonstration must be conducted either during the dark of the night or during daylight
with the dark of the night simulated. If the
demonstration is conducted indoors during
daylight hours, it must be conducted with
each window covered and each door closed to
minimize the daylight effect. Illumination
on the floor or ground may be used, but it
must be kept low and shielded against shining into the airplane-s windows or doors.
(2) The airplane must be in a normal
ground attitude with landing gear extended.
(3) Stands or ramps may be used for descent from the wing to the ground. Safety
equipment such as mats or inverted life rafts
may be placed on the ground to protect participants. No other equipment that is not
part of the airplane-s emergency evacuation
equipment may be used to aid the participants in reaching the ground.
(4) The airplane-s normal electric power
sources must be deenergized.
(5) All emergency equipment for the type
of passenger-carrying operation involved
must be installed in accordance with the certificate holder-s manual.

(6) Each external door and exit and each
internal door or curtain must be in position
to simulate a normal takeoff.
(7) A representative passenger load of persons in normal health must be used. At least
30 percent must be females. At least 5 percent must be over 60 years of age with a proportionate number of females. At least 5 percent, but not more than 10 percent, must be
children under 12 years of age, prorated
through that age group. Three life-size dolls,
not included as part of the total passenger
load, must be carried by passengers to simulate live infants 2 years old or younger.
Crewmembers, mechanics, and training personnel who maintain or operate the airplane
in the normal course of their duties may not
be used as passengers.
(8) No passenger may be assigned a specific
seat except as the Administrator may require. Except as required by item (12) of this
paragraph, no employee of the certificate
holder may be seated next to an emergency
exit.
(9) Seat belts and shoulder harnesses (as
required) must be fastened.
(10) Before the start of the demonstration,
approximately one-half of the total average
amount of carry-on baggage, blankets, pillows, and other similar articles must be distributed at several locations in the aisles
and emergency exit access ways to create
minor obstructions.
(11) The seating density and arrangement
of the airplane must be representative of the
highest capacity passenger version of that
airplane the certificate holder operates or
proposes to operate.
(12) Each crewmember must be a member
of a regularly scheduled line crew, must be
seated in that crewmember-s normally assigned seat for takeoff, and must remain in
that seat until the signal for commencement
of the demonstration is received.
(13) No crewmember or passenger may be
given prior knowledge of the emergency
exits available for the demonstration.
(14) The certificate holder may not practice, rehearse, or describe the demonstration
for the participants nor may any participant
have taken part in this type of demonstration within the preceding 6 months.
(15) The pretakeoff passenger briefing required by Section 125.327 may be given in accordance with the certificate holder-s manual.
The passengers may also be warned to follow
directions of crewmembers, but may not be
instructed on the procedures to be followed
in the demonstration.
(16) If safety equipment as allowed by item
(3) of this section is provided, either all passenger and cockpit windows must be blacked
out or all of the emergency exits must have
safety equipment to prevent disclosure of the
available emergency exits.
(17) Not more than 50 percent of the emergency exits in the sides of the fuselage of an
