during takeoff with the ATTCS system functioning.
I25.4 Thrust Setting.
The initial takeoff thrust or power setting
on each engine at the beginning of the takeoff roll may not be less than any of the following:
(a) Ninety (90) percent of the thrust or
power set by the ATTCS (the maximum
takeoff thrust or power approved for the airplane under existing ambient conditions);
(b) That required to permit normal operation of all safety-related systems and equipment dependent upon engine thrust or power
lever position; or
(c) That shown to be free of hazardous engine response characteristics when thrust or
power is advanced from the initial takeoff
thrust or power to the maximum approved
takeoff thrust or power.
I25.5 Powerplant Controls.
(a) In addition to the requirements of
Section 25.1141, no single failure or malfunction, or
probable combination thereof, of the ATTCS,
including associated systems, may cause the
failure of any powerplant function necessary
for safety.
(b) The ATTCS must be designed to:
(1) Apply thrust or power on the operating
engine(s), following any one engine failure
during takeoff, to achieve the maximum approved takeoff thrust or power without exceeding engine operating limits;
(2) Permit manual decrease or increase in
thrust or power up to the maximum takeoff
thrust or power approved for the airplane
under existing conditions through the use of
the power lever. For airplanes equipped with
limiters that automatically prevent engine
operating limits from being exceeded under
existing ambient conditions, other means
may be used to increase the thrust or power
in the event of an ATTCS failure provided
the means is located on or forward of the
power levers; is easily identified and operated under all operating conditions by a single action of either pilot with the hand that
is normally used to actuate the power levers;
and meets the requirements of Section 25.777 (a),
(b), and (c);
(3) Provide a means to verify to the
flightcrew before takeoff that the ATTCS is
in a condition to operate; and
(4) Provide a means for the flightcrew to
deactivate the automatic function. This
means must be designed to prevent inadvertent deactivation.
I25.6 Powerplant Instruments.
In addition to the requirements of Section 25.1305:
(a) A means must be provided to indicate
when the ATTCS is in the armed or ready
condition; and
(b) If the inherent flight characteristics of
the airplane do not provide adequate warning that an engine has failed, a warning sys-

tem that is independent of the ATTCS must
be provided to give the pilot a clear warning
of any engine failure during takeoff.

APPENDIX J TO PART 25 - EMERGENCY
EVACUATION
The following test criteria and procedures
must be used for showing compliance with
Section 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 Section 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.
