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) For an NVIS operation only, an HLS-NVIS standard 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).

3.05 HLS-NVIS basic
       (1) A rotorcraft for an NVIS flight must not land on or take off from an HLS-NVIS basic unless it is conducting an NVIS operation.
       (2) For subsection (1), the NVIS crew must consist 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 and 1 NVIS trainee pilot; or
(d) 1 NVIS pilot, but only if the flight is conducted by an operator who holds a CASA approval under regulation 91.045 that is based on the applicant's detailed risk assessment.

3.06 No formation flights for NVIS flight
        The pilot in command of an aircraft for an NVIS flight must not engage in formation flight with another aircraft.

3.07 Alternate lighting requirements
       (1) Subject to subsection (2), if an NVIS flight is conducted to a planned destination aerodrome that does not have runway or HLS lighting, then the pilot must nominate a destination alternate aerodrome with lighting for the runway or HLS.
       (2) Subsection (1) does not apply if the NVIS flight is:
(a) an NVIS operation; and
(b) conducted by:
           (i) at least 2 NVIS pilots; or
           (ii) 1 NVIS pilot and 1 NVIS trainee pilot; or
           (iii) 1 NVIS pilot and at least 1 NVIS air crew member.

Division 3 Additional requirements for NVIS operations

3.08 Aircraft lighting
        Despite any other provision of this MOS, if, in an NVIS operation, the optimum performance of the NVIS is affected, or is likely to be affected, by the aircraft's exterior lighting, the pilot in command must:
(a) if satisfied that there is no risk of collision with another aircraft — turn off
