and is required to carry a CVR, shall record on a flight recorder the data link communications
messages.
(c) A helicopter for which the first certificate of airworthiness, for that individual helicopter, was
issued on or after 1 January 2016, which utilizes any of the data link communications
applications listed in 5.1.2 of Appendix 5 to ICAO Annex 6 Part III and is required to carry a CVR,
shall record on a flight recorder the data link communications messages.
(d) A helicopter which is modified on or after 1 January 2016, to install and utilize any of the data link
communications applications listed in 5.1.2 of Appendix 5 to ICAO Annex 6 Part III and is required
to carry a CVR, shall record on a flight recorder the data link communications messages.
Note 1: Data link communications are currently conducted by either ATN-based or FANS 1/A-
equipped aircraft.
Note 2: A Class B AIR could be a means for recording data link communications applications
messages to and from the aeroplanes where it is not practical or is prohibitively expensive to
record those data link communications applications messages on FDR or CVR.

(e) The minimum recording duration shall be equal to the duration of the CVR.
(f) Data link recording shall be able to be correlated to the recorded cockpit audio.
OTAR.125.770 Ground proximity warning system
(a) A turbine-engined aeroplane of MTOM 5,700 kg or less and with a maximum approved
passenger seating configuration of more than 5 but not more than 9 seats shall be equipped with
a ground proximity warning system which has a forward looking terrain avoidance function.
(b) A turbine-engined aeroplane with MTOM exceeding 5,700 kg or with a maximum approved
passenger seating configuration of more than 9 seats shall be equipped with a ground proximity
warning system which has a forward looking terrain avoidance function.
(c) A piston-engined aeroplane with MTOM exceeding 5,700 kg or with a maximum approved
passenger seating configuration of more than 9 seats shall be equipped with a ground proximity
warning system which has a forward looking terrain avoidance function.
(d) A ground proximity warning system required to be carried in accordance with paragraph (a), (b)
or (c) shall provide an automatic and distinctive warning to the flight crew when the aeroplane is
in potentially hazardous proximity to the earth’s surface.
(e) A ground proximity warning system required to be carried in accordance with paragraph (a), (b)
or (c) shall provide, as a minimum, warnings of at least the following circumstances:
(1) excessive descent rate;
(2) excessive altitude loss after take-off or go-around; and
(3) unsafe terrain clearance.
Note: Terrain Awareness and Warning System (TAWS) Class B will provide the parameters
required in (e) above.
(f) A turbine-engined aeroplane with MTOM exceeding 5 700 kg, or with a maximum approved
passenger seating configuration of more than 9 seats for which the first certificate of
airworthiness, for that individual aeroplane, was issued after 1 January 2011 shall be equipped
with a ground proximity warning system which has a forward looking terrain avoidance function.
(g) A ground proximity warning system required to be carried in accordance with paragraph (f) shall
provide an automatic and distinctive warning to the flight crew when the aeroplane is in
potentially hazardous proximity to the earth’s surface.
(h) A ground proximity warning system required to be carried in accordance with paragraph (f) shall
provide, as a minimum, warnings of at least the following circumstances:
(1) excessive descent rate;
(2) excessive terrain closure rate;
(3) excessive altitude loss after take-off or go-around;
(4) unsafe terrain clearance while not in the landing configuration;
1) gear not locked down;
2) flaps not in a landing position; and
(5) excessive descent below the instrument glide path.
Note: Terrain Awareness and Warning System (TAWS) Class A will provide the parameters
required in (h) above.
OTAR.125.775 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 aeroplane is being operated in
areas where such conditions may be expected to exist along the route in instrument meteorological
conditions or at night.
OTAR.125.785 Airborne collision avoidance system (ACAS II)
(a) An airborne collision avoidance, if required or fitted, system shall operate in accordance with the
relevant provisions of ICAO Annex 10, Volume IV.
