 (9) For paragraph (5)(b):

 (a) the original manufacturer of the NVIS; or

11.64  Minimum equipment for NVIS flight
 (1) Subject to subsection (2), before an NVIS flight, the rotorcraft must be fitted with a serviceable radio altimeter that:
 (a) conforms to the following requirements:
 (i) it must have a presentation that requires minimal interpretation for both an instantaneous impression of absolute height and rate of change of height;
 (ii) it must be positioned to be instantly visible and discernible to each NVIS crew member from the person's station in the cockpit;
 (iii) it must have an integral audio and visual low height warning that operates at a height selectable by the pilot;
 (iv) it must provide unambiguous warning to each NVIS crew member of radio altimeter failure; and
 (b) has a visual warning system that provides clear visual warning at each cockpit crew station of height below the pilot-selectable height; and
 (c) has an audio warning system that:
 (i) is unambiguous and readily cancellable; and
 (ii) when cancelled — does not extinguish any visual low height warnings; and
 (iii) operates at the same pilot-selectable height as the visual warning.
 (2) CASA may approve an alternative visual and audio warning system that must be fitted to a rotorcraft before an operation, but only if the system produces warnings at least equivalent to those mentioned in paragraphs (1)(b) and (c).
 (3) Before an NVIS flight, the rotorcraft must be fitted with a serviceable pilot-steerable searchlight, adjustable in both pitch and azimuth from the flight controls.
 (4) Before an NVIS flight, the operator and the pilot in command must be satisfied that:
 (a) in an NVIS operation below 500 ft AGL; or
 (b) in an NVIS operation from an HLS-NVIS basic using a searchlight with an NVIS compatible IR filter;
the risk of an adverse event as a result of NVIS failure below 500 ft AGL is controlled by:
 (c) the rotorcraft's capacity to revert immediately to a non-filtered search or landing light; or
 (d) the presence of 2 pilots, each of whom:
 (i) is NVIS qualified and NVIS equipped; and
 (ii) has access to dual flight controls.
