Regulation OTAR Part 91 - General Operating Instructions

(i) certificated for ditching or, for coastal transit operations only, be fitted with a
permanent or rapidly deployable means of flotation so as to ensure a safe
ditching of the helicopter; and
(ii) liferaft(s) sufficient to carry all persons on board, suitably equipped to sustain
life in the expected conditions; and
(iii) equipment for making the distress signals described in the Rules of the Air;
and
(iv) any additional equipment decided by reference to the assessment in
91.710(c).
Performance Class 3 operations –
(4) A helicopter operating in performance Class 3 when flying beyond auto-rotational or
safe forced landing distance from land, shall be equipped as follows:
(i) be fitted with a permanent or rapidly deployable means of flotation so as to
ensure a safe ditching of the helicopter; and
(ii) when not precluded by consideration related to the type of helicopter used,
life raft(s) sufficient to carry all persons on board, suitably equipped to
sustain life in the expected conditions; and
(iii) equipment for making the distress signals described in the Rules of the Air.
(iv) any additional equipment decided by reference to the assessment in
91.710(c).

OTAR.91.720 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
OTAR.91.730 Oxygen indicators
An aircraft operated at altitudes above flight level 130, or for more than 30 minutes between flight level 100
up to and including flight level 130, shall be equipped with a means of indicating:
(a) to the flight crew:
(1) the amount of breathing 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 breathing oxygen dispensing unit, the amount of oxygen available
and whether the oxygen is being delivered to the dispensing unit
OTAR.91.735 Oxygen equipment and supplies for non-pressurised aircraft
An aircraft with a non-pressurised cabin that is operated at altitudes above flight level 100 shall be equipped
with oxygen storage and dispensing equipment to supply the following:
(1) at altitudes up to and including flight level 130 for any period in excess of 30 minutes:
stored breathing oxygen for continuous use by all crew members and 10 % of the passengers;
and
(2) at altitudes above flight level 130:
stored breathing oxygen for continuous use by all crew members and passengers.
OTAR.91.740 Oxygen equipment and supplies for pressurised aircraft
(a) An aircraft with a pressurised cabin that is to be operated at altitudes above flight level 100 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) the following equipment that is readily accessible to each crew member, other than
flight crew, at their normally-seated position:
(i) a crew member on demand oxygen mask; or
(ii) a passenger oxygen mask; and
(iii) portable breathing equipment for immediate use containing the greater of 120
litres of oxygen or the quantity of oxygen required for continuous use for that
time the cabin pressure altitude would exceed 10,000 feet.
(b) For the purposes of paragraph (a), the calculation of the oxygen requirements in the event of
pressurisation failure is to take into account:
(1) the time necessary for an emergency descent and the recovery phase to level flight at
a safe altitude; and
