Note: A different runway is any runway at the aerodrome with a different runway number. Separate runways are runways at the same aerodrome that would be usable if they are configured in such a way that if one runway were closed, an operation to another runway is operationally available to the aeroplane. Separate runways cannot be at the opposite ends of the same runway.

Ceiling and visibility minima—certain GAF or GAMET area forecasts
 (2) If the authorised weather forecast for an aerodrome is a GAF or GAMET area forecast, then, the aerodrome may be planned for use as a destination alternate aerodrome or an en‑route alternate aerodrome (other than an EDTO en‑route alternate aerodrome) only if the relevant weather conditions are not, during the estimated time of use at the aerodrome, forecast to exist below the following cloud ceiling and visibility values:
 (a) for an aerodrome with at least one authorised instrument approach procedure:
 (i) for cloud ceiling—the circling minimum altitude specified on the instrument approach chart for the instrument approach procedure being conducted, plus 500 ft; and
 (ii) for visibility—the circling visibility specified on the instrument approach chart for the instrument approach procedure being conducted, plus 2 km;
 (b) for an aerodrome without an authorised instrument approach procedure:
 (i) for cloud ceiling—the lowest safe altitude for the last route segment to the aerodrome, plus 500 ft; and
 (ii) for visibility—8 km.

4.12  Isolated destination aerodromes
 (1) The requirements in this section apply in relation to the flight of an aeroplane to a planned destination aerodrome that is an isolated destination aerodrome.
 (2) A critical point must be calculated before the commencement of the flight.
Note: Section 5.01 requires that the calculated critical point must be included on the operational flight plan before the flight commences.
 (3) The flight must not be continued beyond the critical point unless:
 (a) an assessment of the authorised weather forecast relevant to the aerodrome; and
 (b) the aircraft traffic and other operational conditions relevant to conducting an approach and landing at the aerodrome;
indicate that a safe landing can be made at the estimated time of use.
 (4) For subsection (3), if the authorised weather forecast assessed for flight beyond the critical point is an aerodrome forecast or an ICAO landing forecast, the cloud ceiling and visibility requirements for continuing beyond the critical point are those specified in table 4.11.
 (5) For subsection (3), if the authorised weather forecast assessed for flight beyond the critical point is a GAF or GAMET area forecast:
 (a) the cloud ceiling
