26.23 Operation of surveillance equipment — general requirements
       (1) Surveillance equipment required to be fitted to, or carried on, a Part 131 aircraft by section 26.21 must be continuously operated during the circumstances mentioned in section 26.21.
Note   Continuous operation for a transponder implies that the equipment must be operated in a mode that enables an SSR response to be transmitted and, where an altitude reporting capability is available, that this capability is also activated.
       (2) Surveillance equipment (other than approved transponders) fitted to, or carried on, a Part 131 aircraft for section 26.22 must be continuously operated during the circumstances mentioned in that section for the specific kind of equipment.
       (3) Subsections (1) and (2) do not apply if ATC has issued an instruction that the surveillance equipment is not to be operated.
       (4) Unless otherwise required by ATC, a Part 131 aircraft that is flying in formation with, or flying in-company with, 1 or more other Part 131 aircraft, is not required to operate surveillance equipment if serviceable surveillance equipment is operated by the other, or 1 of the other, Part 131 aircraft at all times while the aircraft are flying in the formation or flying in-company.
       (5) If a Part 131 aircraft for a flight is fitted with, or carries, more than 1 approved transponder, only 1 of the transponders is to be operated at any time.
       (6) If a Part 131 aircraft is fitted with, or carries, an approved transponder for a flight, the Mode A code must be set:
(a) to the transponder code assigned by ATS for the flight; or
(b) if no transponder code is so assigned — to the relevant standard code mentioned in Table 26.23 (7).
       (7) For paragraph (6) (b), for a situation mentioned in column 1 of an item in Table 26.23 (7), the Mode A code is the number mentioned in column 2 for the same item.
       (8) Subject to subsection (9), if an emergency situation described in an item of column 1 of Table 26.23 (8) occurs during a flight, a pilot of the aircraft for the flight must set the Mode
