Regulation OTAR Part 121 - CAT - Large Aeroplanes

(5) liferafts shall be equipped in accordance with Appendix B.
(6) An aeroplane with MTOM exceeding 27,000 kg shall be equipped with a securely
attached underwater locating beacon (ULB). The ULB shall be automatically activating,
operate at a frequency of 8.8 kHz for a minimum of 30 days and shall not be installed in
wings or empennage.
(g) A multi-engine aeroplane capable of continuing flight without descending below the minimum
flight altitude after an engine failure, if operating over water more than 90 minutes at cruising
speed or 200 NM, whichever is less, from land suitable for making an emergency landing shall be
equipped as follows:
(1) a lifejacket, or equivalent individual flotation device, for every person on board; and
(2) liferafts in sufficient numbers to carry all persons on board, stowed so as to facilitate
their ready use in emergency, provided with such life-saving equipment, including
means of sustaining life, as is appropriate to the flight to be undertaken; and
(3) equipment for making the distress signals described in the Rules of the Air.
(4) buoyancy and rated capacity shall be sufficient to accommodate all occupants of the
aeroplane in the event of a loss of one raft of the largest rated capacity; and
(5) liferafts shall be equipped in accordance with Appendix B.
(6) An aeroplane with MTOM exceeding 27,000 kg shall be equipped with a securely
attached underwater locating beacon (ULB). The ULB shall be automatically activating,
operate at a frequency of 8.8 kHz for a minimum of 30 days and shall not be installed in
wings or empennage.
Note: Underwater Locator Beacon (ULB) performance requirements are as contained
in the SAE AS6254, Minimum Performance Standard for Underwater Locating Devices
(Acoustic) (Self- Powered), or equivalent documents.

OTAR.121.720 Transponder
(a) An aircraft shall be equipped with a pressure-altitude reporting secondary surveillance radar
(SSR) transponder and any other SSR transponder capability that is required for the route being
flown.
Note 1: The SSR transponders should operate in accordance with the relevant provisions of
ICAO Annex 10, Volume
(b) An aeroplane shall be equipped with a data source that provides pressure altitude information
with a resolution of 25 ft (7.62 m) or better.
(c) A Mode S transponder shall be provided with the airborne/on-the-ground status where the aircraft
is equipped with an automatic means of detecting such status.
OTAR.121.725 Passenger safety instructions
An aircraft shall be equipped with a means of conveying the following information and instructions to

(e) location of emergency equipment; and
(f) location and method of opening emergency exits.
OTAR.121.730 Oxygen indicators
An aircraft operated above flight level 100 shall be equipped with a means of indicating:
(a) to the flight crew:
(1) the amount of oxygen available in each source of supply and whether the oxygen is
being delivered to the dispensing units; and
(2) in a pressurised aircraft, by visual or aural warning, when the cabin pressure altitude
exceeds 10,000 feet; and
(b) to each user of an individual dispensing unit, the amount of oxygen available and whether the
oxygen is being delivered to the dispensing unit.
OTAR.121.735 Non-pressurised aircraft
The operator shall ensure that an aircraft with a non-pressurised cabin is not operated above flight level
100, except in accordance with an approval granted by the Governor.
OTAR.121.740 Oxygen equipment and supplies for pressurised aeroplanes
(a) An aircraft with a pressurised cabin that is to be operated at altitudes above flight level 100 up to
and including flight level 250 shall be equipped with:
(1) a crew member on-demand oxygen mask accessible to each flight crew member and
capable of providing a continuous supply of stored breathing oxygen for that time
following failure of the pressurisation system that the cabin pressure altitude would
exceed 10,000 feet; and
(2) oxygen masks capable of providing supplemental oxygen to all passengers; and
