Part 91 of CASR:
            (A) of climbing to the minimum height required under regulation 91.265, 91.267, 91.277 or 91.305, as applicable for the flight; and
            (B) thereafter, of flying to a suitable aerodrome for landing;
(d) for a rotorcraft:
           (i) except when complying with sections 9.04, 9.12 and 9.13 — the rotorcraft's minimum airspeed must be not less than whichever of the following is the greatest:
            (A) Vmini;
            (B) Vy for the rotorcraft;
            (C) 60 kts; and
           (ii) except when operating at an ESO operating site — the rotorcraft must be a multi-engine rotorcraft operated with OEI accountability during the operation.

9.11 Radar and instruments
       (1) An aircraft must be fitted with the following equipment:
(a) a radar that has a ground-mapping function;
(b) a radio altimeter;
(c) a navigation system.
       (2) Operations must not be commenced, or if commenced must be discontinued immediately, if:
(a) any of the equipment required for the operation fails or has failed; or
       Note   For equipment requirements, see Subpart 138.K, and Part 91, of CASR.
(b) the equipment mentioned in subsection (1) fails or has failed; or
(c) there is a RAIM warning or any reason to doubt the integrity of the GNSS‑derived information; or
(d) there is a RAIM loss.

9.12 Visibility
       (1) Operations must not be conducted unless visibility:
(a) at 1 000 ft above sea level — for aeroplanes; or
(b) at 700 ft above sea level — for rotorcraft;
        meets the VMC criteria for:
(c) the category of aircraft used in the operation; and
(d) the class of airspace within which the aircraft is operating during the operation.
       (2) For an operation in cloud below minimum height the requirements are as follows:
(a) the minimum descent altitude to obtain visual reference below cloud must not be less than 1 000 ft above sea level for aeroplanes, or 700 ft above sea level for rotorcraft, derived from the aircraft radio altimeter;
(b) if:
 (i) visibility prescribed in subsection (1) is not obtained; or
 (ii) visibility below cloud is reduced to less than that required under subsection (1);
 then the pilot in command must immediately return the aircraft to at least minimum height.
       (3) After visual investigation of a target or search area, the aircraft must immediately initiate a climb to at least minimum height, unless section 9.13 applies.

9.13 Minimum altitude
       (1) Subject to subsection (2), the minimum altitude must be not lower than 500 ft, derived from the aircraft radio altimeter.
       (2) A rotorcraft may descend below 500 ft, by day only, to identify a person or object, or to rescue a person, if the following requirements are met:
(a) at least the minimum visibility to maintain VMC is available
