Appendix J to Part 25 - Emergency Evacuation
The following test criteria and procedures must be used for
showing compliance with § 25.803:
(a) The emergency evacuation must be conducted with exterior
ambient light levels of no greater than 0.3 foot-candles prior to
the activation of the airplane emergency lighting system. The
source(s) of the initial exterior ambient light level may remain
active or illuminated during the actual demonstration. There must,
however, be no increase in the exterior ambient light level except
for that due to activation of the airplane emergency lighting
system.
(b) The airplane must be in a normal attitude with landing gear
extended.
(c) Unless the airplane is equipped with an off-wing descent
means, 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 floor or ground to protect participants. No other
equipment that is not part of the emergency evacuation equipment of
the airplane may be used to aid the participants in reaching the
ground.
(d) Except as provided in paragraph (a) of this appendix, only
the airplane's emergency lighting system may provide
illumination.
(e) All emergency equipment required for the planned operation
of the airplane must be installed.
(f) Each internal door or curtain must be in the takeoff
configuration.
(g) Each crewmember must be seated in the normally assigned seat
for takeoff and must remain in the seat until receiving the signal
for commencement of the demonstration. Each crewmember must be a
person having knowledge of the operation of exits and emergency
equipment and, if compliance with § 121.291 is also being
demonstrated, each flight attendant must be a member of a regularly
scheduled line crew.
(h) A representative passenger load of persons in normal health
must be used as follows:
(1) At least 40 percent of the passenger load must be
female.
(2) At least 35 percent of the passenger load must be over 50
years of age.
(3) At least 15 percent of the passenger load must be female and
over 50 years of age.
(4) 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.
(5) Crewmembers, mechanics, and training personnel, who maintain
or operate the airplane in the normal course of their duties, may
not be used as passengers.
(i) No passenger may be assigned a specific seat except as the
Administrator may require. Except as required by subparagraph (g)
of this paragraph, no employee of the applicant may be seated next
to an emergency exit.
(j) Seat belts and shoulder harnesses (as required) must be
fastened.
(k) 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 aisles and emergency exit access ways to create minor
obstructions.
(l) No prior indication may be given to any crewmember or
passenger of the particular exits to be used in the
demonstration.
(m) The applicant 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.
(n) Prior to entering the demonstration aircraft, the passengers
may also be advised to follow directions of crewmembers but may not
be instructed on the procedures to be followed in the
demonstration, except with respect to safety procedures in place
for the demonstration or which have to do with the demonstration
site. Prior to the start of the demonstration, the pre-takeoff
passenger briefing required by § 121.571 may be given. Flight
attendants may assign demonstration subjects to assist persons from
the bottom of a slide, consistent with their approved training
program.
(o) The airplane must be configured to prevent disclosure of the
active emergency exits to demonstration participants in the
airplane until the start of the demonstration.
(p) Exits used in the demonstration must consist of one exit
from each exit pair. The demonstration may be conducted with the
escape slides, if provided, inflated and the exits open at the
beginning of the demonstration. In this case, all exits must be
configured such that the active exits are not disclosed to the
occupants. If this method is used, the exit preparation time for
each exit utilized must be accounted for, and exits that are not to
be used in the demonstration must not be indicated before the
demonstration has started. The exits to be used must be
representative of all of the emergency exits on the airplane and
must be designated by the applicant, subject to approval by the
Administrator. At least one floor level exit must be used.
(q) Except as provided in paragraph (c) of this section, all
evacuees must leave the airplane by a means provided as part of the
airplane's equipment.
(r) The applicant's approved procedures must be fully utilized,
except the flightcrew must take no active role in assisting others
inside the cabin during the demonstration.
(s) The evacuation time period is completed when the last
occupant has evacuated the airplane and is on the ground. 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, evacuees
using stands or ramps allowed by paragraph (c) of this appendix are
considered to be on the ground when they are on the stand or
ramp.
