Appendix B to Part 125 - Criteria for Demonstration of Emergency
Evacuation Procedures Under § 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 § 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 airplane that meet all of the
requirements applicable to the required emergency exits for that
airplane may be used for the demonstration. Exits that are not to
be used in the demonstration must have the exit handle deactivated
or must be indicated by red lights, red tape or other acceptable
means, placed outside the exits to indicate fire or other reason
that they are unusable. The exits to be used must be representative
of all of the emergency exits on the airplane and must be
designated by the certificate holder, subject to approval by the
Administrator. At least one floor level exit must be used.
(18) All evacuees, except those using an over-the-wing exit,
must leave the airplane by a means provided as part of the
airplane's equipment.
(19) The certificate holder's approved procedures and all of the
emergency equipment that is normally available, including slides,
ropes, lights, and megaphones, must be fully utilized during the
demonstration.
(20) The evacuation time period is completed when the last
occupant has evacuated the airplane and is on the ground. Evacuees
using stands or ramps allowed by item (3) above are considered to
be on the ground when they are on the stand or ramp:
Provided, That the acceptance rate of the stand or ramp is
no greater than the acceptance rate of the means available on the
airplane for descent from the wing during an actual crash
situation.
(b) Ditching demonstration. The demonstration must assume
that daylight hours exist outside the airplane and that all
required crewmembers are available for the demonstration.
(1) If the certificate holder's manual requires the use of
passengers to assist in the launching of liferafts, the needed
passengers must be aboard the airplane and participate in the
demonstration according to the manual.
(2) A stand must be placed at each emergency exit and wing with
the top of the platform at a height simulating the water level of
the airplane following a ditching.
(3) After the ditching signal has been received, each evacuee
must don a life vest according to the certificate holder's
manual.
(4) Each liferaft must be launched and inflated according to the
certificate holder's manual and all other required emergency
equipment must be placed in rafts.
(5) Each evacuee must enter a liferaft and the crewmembers
assigned to each liferaft must indicate the location of emergency
equipment aboard the raft and describe its use.
(6) Either the airplane, a mockup of the airplane, or a floating
device simulating a passenger compartment must be used.
(i) If a mockup of the airplane is used, it must be a life-size
mockup of the interior and representative of the airplane currently
used by or proposed to be used by the certificate holder and must
contain adequate seats for use of the evacuees. Operation of the
emergency exits and the doors must closely simulate that on the
airplane. Sufficient wing area must be installed outside the
over-the-wing exits to demonstrate the evacuation.
(ii) If a floating device simulating a passenger compartment is
used, it must be representative, to the extent possible, of the
passenger compartment of the airplane used in operations. Operation
of the emergency exits and the doors must closely simulate
operation on that airplane. Sufficient wing area must be installed
outside the over-the-wing exits to demonstrate the evacuation. The
device must be equipped with the same survival equipment as is
installed on the airplane, to accommodate all persons participating
in the demonstration.
