       Note   Obstacles required for air navigation include, for example, a wind direction indicator.
(b) whose purpose is to reduce the risk of damage to an aircraft accidentally diverging from the load-bearing area primarily intended for landing or take-off.
Note   The safety area does not need to be a solid surface. For example, a perforated metal deck may constitute part, or all, of a safety area.

Division 2 — Requirements for NVIS operations

12.04 General HLS-NVIS requirements
        An aircraft in an NVIS operation may only take off from and land on:
(a) an HLS-NVIS standard; or
(b) subject to section 12.06 — an HLS-NVIS basic.

12.05 HLS-NVIS standard
       (1) Subject to subsection (2), an HLS-NVIS standard is an HLS that meets all of the following requirements:
(a) the FATO must at least:
           (i) be capable of enclosing a circle with a diameter equal to one and a half times the D-Value (1.5 x D) of the rotorcraft; and
           (ii) be free of obstacles likely to interfere with the manoeuvring of the rotorcraft; and
           (iii) incorporate a safety area of 0.25 x D, or 3 m around the FATO, whichever is larger;
(b) a TLOF must be at least:
           (i) a cleared and, as far as practicable, stable area capable of bearing the dynamic loads which may be imposed by the rotorcraft; and
           (ii) an area of 0.83 x D.
       (2) An HLS-NVIS standard for a particular NVIS operation also includes an HLS that meets the FATO and TLOF criteria determined by the NVIS operator through a risk assessment, provided that the FATO and the TLOF so determined will deliver a level of safety that is at least equivalent to that which would otherwise arise from compliance with paragraphs (1) (a) and (b).

12.06 HLS-NVIS basic
        A rotorcraft for an NVIS operation may land on or take off from an HLS-NVIS basic but only if the NVIS crew consists of:
(a) at least 2 NVIS pilots; or
(b) 1 NVIS pilot and at least 1 NVIS air crew member; or
(c) 1 NVIS pilot, but only if the operation is conducted by an NVIS operator who holds a CASA approval under subregulation 138.025 (1) that is based on the operator's detailed risk assessment.

12.07 No formation flights
        The pilot in command of an aircraft for an NVIS operation must
