Pt. 125, App. D

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 overthe-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-thewing 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.

APPENDIX C TO PART 125 - ICE
PROTECTION
If certification with ice protection provisions is desired, compliance with the following must be shown:
(a) The recommended procedures for the
use of the ice protection equipment must be
set forth in the Airplane Flight Manual.
(b) An analysis must be performed to establish, on the basis of the airplane-s operational needs, the adequacy of the ice protection system for the various components of
the airplane. In addition, tests of the ice protection system must be conducted to demonstrate that the airplane is capable of operating safely in continuous maximum and
intermittent maximum icing conditions as
described in appendix C of part 25 of this
chapter.
(c) Compliance with all or portions of this
section may be accomplished by reference,
where applicable because of similarity of the
designs, to analyses and tests performed by
the applicant for a type certificated model.
