3                                                             A non-precision approach procedure (other than an RNP APCH‑LNAV/VNAV or RNP APCH‑LPV) that involves the conduct of a circling manoeuvre          A height of 400 ft above:                                         Visibility of 1 500 m above the published visibility
                                                                                                                                                                                                               (a) the published circling altitude or circling height; or
                                                                                                                                                                                                               (b) the value determined for those elements under subsection (5)

 (7) In an item of table 4.19:
published means published in the authorised aeronautical information for the purposes of the instrument approach procedure mentioned in column 1 that is planned to be used.

Alternative planning minima—low-visibility EDTO
 (8) Despite subsection (4), the alternative requirement in subsection (9) applies if:
 (a) the runway anticipated to be used at the aerodrome has a serviceable precision approach procedure for the runway that is an authorised instrument approach procedure; and
 (b) that procedure has either a Category II or Category III minima published in the authorised aeronautical information; and
 (c) the operator holds an approval, under regulation 91.045 of CASR for the purposes of regulation 91.315 of CASR, to conduct a low-visibility operation that is Category II or Category III; and
 (d) the aeroplane is capable of conducting an instrument approach procedure to Category II or Category III minima with one engine inoperative; and
 (e) the operator holds an EDTO approval for the aeroplane that permits the operator to use cloud ceiling and visibility values lower than those specified in table 4.19.
 (9) An aerodrome forecast, or ICAO landing forecast, must indicate that relevant weather conditions, during any part of the estimated time of use at the aerodrome, are not forecast to exist below the cloud ceiling and visibility values determined in accordance with the values permitted under the EDTO approval.
Note: A GAF or a GAMET area forecast is not sufficient to meet the requirement for an aerodrome forecast (defined in section 4.02) or an ICAO landing forecast.

4.20  Requirements in Division 2 may be varied
  A requirement imposed by a provision in this Division is subject to an approval mentioned in subsection 4.21(1).

Division 3—Operational variations of the flight preparation (Part 121 alternate aerodromes) requirements

4.21  Operational variation approvals—alternate aerodrome requirements
 (1) An operational variation to a requirement imposed by a provision of Division 2 of this Chapter applies if an operator, who meets the requirement in subsection (2), holds an approval under regulation 121.010 of CASR that specifies the operational variation.
 (2) The operator must have submitted to CASA a specific safety risk assessment:
 (a) that demonstrates how an operational variation will maintain or improve safety; and
 (b) that takes into account, and includes information about, at least the following matters:
 (i) the capabilities of the operator;
 (ii) the overall capability of the aeroplane and its
