Regulation OTAR Part 121 - CAT - Large Aeroplanes

Note: Terrain Awareness and Warning System (TAWS) Class A will provide the parameters
required in (e) above.

OTAR.121.775 Significant weather detection
A pressurised aeroplane:
when carrying passengers shall be equipped with operative weather radar or other significant-weather
detecting equipment capable of detecting thunderstorms whenever the aircraft is being operated in areas
where such conditions may be expected to exist along the route in instrument meteorological conditions or
at night.
OTAR.121.780 Turbo-jet aeroplanes - forward-looking wind shear warning system
(a) A turbo-jet aeroplane with MTOM exceeding of 5,700 kg or with a maximum approved passenger
seating configuration of more than 9 seats shall be equipped with a forward-looking wind shear
warning system.
(b) A forward-looking wind shear warning system shall be capable of providing the pilot with a timely
aural and visual warning of wind shear ahead of the aircraft, and the information required to
permit the pilot to safely commence and continue a missed approach or go-around or to execute
an escape manoeuvre if necessary. The system should also provide an indication to the pilot
when the limits specified for the certification of automatic landing equipment are being
approached, when such equipment is in use.
OTAR.121.785 Airborne collision avoidance system (ACAS II)
(a) An airborne collision avoidance system, if required or fitted, shall operate in accordance with the
relevant provisions of ICAO Annex 10, Volume IV.
Note 1: TCAS II Version 7.1 is required for compliance with ICAO ACAS II technical standards.
(b) A turbine-engined aeroplane with MTOM exceeding 5,700 kg, or with a maximum approved
passenger seating configuration of more than 19 seats, shall be equipped with an airborne
collision avoidance system (ACAS II).
OTAR.121.790 Cosmic radiation detection equipment
(a) An aeroplane flying above 49,000 feet shall carry equipment to measure and indicate
continuously the dose rate of total cosmic radiation being received (i.e. the total of ionizing and
neutron radiation of galactic and solar origin) and the cumulative dose on each flight.
(b) The display unit of the equipment shall be readily visible to a flight crew member.
OTAR.121.800 Electronic Flight Bags (EFBs)
(a) The operator may, with the approval of the Governor, operationally use EFBs.
(b) The operator shall ensure that:
(1) EFBs do not affect the performance of the aeroplane systems, equipment or the ability
to operate the aearoplane.
(2) Assess the risk(s) associated with each EFB function.
(3) Establish and document the procedures for the use of, and training requirements for,
the device and each EFB function.
(4) ensure that in the event of an EFB failure, sufficient information is readily available to
the flight crew for the flight to be conducted safely.
Note: Guidance is ICAO Doc. 10020 Manual of Electronic Flight Bags (EFBs).
Note: When complying with 121.800(b), the operator should utilise his safety
management system, and ensure that the standard operating procedures requirements
in 121.170 are satisfied.
OTAR.121.905 Composition of crew
The operator shall ensure that:
(a) the number and composition of the flight crew shall not be less than that specified in the
operations manual. The flight crew shall include flight crew members in addition to the minimum
numbers specified in the flight manual or other documents associated with the certificate of
airworthiness, when necessitated by considerations related to the type of aeroplane used, the
type of operation involved and the duration of flight between points where flight crews are
changed.

OTAR.121.910 Flight crew qualification
The operator shall ensure that:
each flight crew member assigned to duty:
(1) meets all requirements for the assigned flight-crew duty; and
(2) meets all route and aerodrome qualification requirements for the operation intended.
(3) is currently qualified in accordance with the requirements of Subpart I.

OTAR.121.915 Flight crew recency
(a) The operator shall not assign a pilot-in-command or a co-pilot to operate at the flight controls of a
type or variant of a type of aeroplane during take-off and landing unless that pilot has operated the
flight controls during at least three take-offs and landings within the preceding 90 days on the
same type of aeroplane or in a flight simulator approved for the purpose; and
