(c) The pilot-in-command of an aeroplane operated at a distance away from land where an
emergency landing is possible greater than that corresponding to 30 minutes at normal
cruising speed or 50 NM, whichever is the lesser, shall determine the risks to survival of
the occupants of the aeroplane in the event of a ditching, based on which he/she shall
determine the carriage of:
(1) equipment for making the distress signals;
(2) life-rafts in sufficient numbers to carry all persons on board, stowed so as to
facilitate their ready use in emergency; and
(3) life-saving equipment, to provide the means of sustaining life, as appropriate to the
flight to be undertaken.

ACCESSIBILITY OF LIFE-JACKETS
The life-jacket, if not worn, should be accessible from the seat or berth of the person for whose use it
is provided, with a safety belt or a restraint system fastened.
MEANS OF ILLUMINATION FOR LIFE-JACKETS
Each life-jacket or equivalent individual flotation device should be equipped with a means of electric
illumination for the purpose of facilitating the location of persons.
RISK ASSESSMENT
(a) When conducting the risk assessment, the pilot-in-command should base his/her
decision, as far as is practicable, on the Implementing Rules and AMCs applicable to the
operation of the aeroplane.
(b) The pilot-in-command should, for determining the risk, take the following operating
environment and conditions into account:
(1) sea state;
(2) sea and air temperatures;
(3) the distance from land suitable for making an emergency landing; and
(4) the availability of search and rescue facilities.

SEAT CUSHIONS
Seat cushions are not considered to be flotation devices.
NCO.IDE.A.180 Survival equipment
Aeroplanes operated over areas in which search and rescue would be especially difficult shall be
equipped with such signalling devices and life-saving equipment, including means of sustaining life,
as may be appropriate to the area overflown.
NCO.IDE.A.180 AMC1 Survival equipment
GENERAL
(a) Aeroplanes operated across land areas in which search and rescue would be especially
difficult should be equipped with the following:
(1) signalling equipment to make the distress signals;
(2) at least one ELT(S) or a PLB, carried by the pilot-in-command or a passenger; and
(3) additional survival equipment for the route to be flown, taking account of the
number of persons on board.
(b) The additional survival equipment specified in (a)(3) does not need to be carried when the
aeroplane remains within a distance from an area where search and rescue is not
especially difficult, that corresponds to:
(1) 120 minutes at one-engine-inoperative (OEI) cruising speed for aeroplanes
capable of continuing the flight to an aerodrome with the critical engine(s)
becoming inoperative at any point along the route or planned diversion routes; or
(2) 30 minutes at cruising speed for all other aeroplanes.
NCO.IDE.A.180 AMC2 Survival equipment
ADDITIONAL SURVIVAL EQUIPMENT

(1) 500 ml of water for each four, or fraction of four, persons on board;
(2) one knife;
(3) first-aid equipment; and
