ADS-B in transponder mandatory controlled airspace.

(a) Except as provided in rules 91.253, 91.255D and 91.255E, a person must not operate an aircraft in transponder mandatory controlled airspace designated under Part 71 in the New Zealand FIR unless the aircraft is equipped with an ADS-B system which meets the minimum performance standards and requirements under rule 91.257. (b) Paragraph (a) does not apply to an aircraft operating in any portion of the airspace within the Auckland Oceanic FIR.

An ADS-B system must meet the following minimum requirements – (1) include a 1090 MHz Mode S Extended Squitter transponder, or any other suitable transponder determined by the Director as specified in a notice referred to in rule 91.258; (2) include a GNSS position source that is compatible with the 1090 MHz Mode S Extended Squitter transponder, or any other suitable transponder referred to in paragraph (1); (3) include a barometric altitude pressure system and any related equipment;

(a) Except as provided in paragraph (g), a pilot-in-command of an aircraft operating in transponder mandatory controlled airspace designated under Part 71 within the New Zealand FIR must, unless otherwise authorised or instructed by ATC— (1) operate the transponder to transmit ADS-B data; and (2) ensure that ADS-B data is transmitted at all times when the aircraft begins to move under its own power until it has come to a complete stop at the end of the flight.

(a) Despite rule 91.255(a), a person may operate an aircraft without transmitting ADS-B data in the prescribed airspace referred to in that rule if the aircraft cannot practicably or reasonably be equipped with an ADS-B system because of the characteristics of the aircraft type. (b) Before operating an aircraft referred to in paragraph (a), the person must obtain specific authorisation from the ATC unit having jurisdiction over the relevant airspace as part of the ATC clearance to enter that airspace.
