weather conditions are forecast to be below the landing minima determined by the operator under regulation 121.185 of CASR for the flight; or
 (b) an authorised weather forecast for the planned destination aerodrome is either not available for the estimated time of use, or does not completely encompass the estimated time of use.

Exception
 (3) It is an exception to the requirement in subsection (1) if:
 (a) one destination alternate aerodrome is planned for the flight; and
 (b) that aerodrome meets the requirements in subsection 4.08(3), applied as if the reference to an aerodrome in that subsection were a reference to the destination alternate aerodrome planned for the flight.

Ceiling and visibility minima—general
 (1) Subject to subsection (2), an aerodrome may be planned for use as:
 (a) an en‑route alternate aerodrome; or
 (b) a destination alternate aerodrome; or
 (c) an isolated destination aerodrome;
in relation to an approach facility configuration mentioned in column 1 of an item of the table 4.11, only if an authorised weather forecast for the aerodrome indicates that, during the estimated time of use at the aerodrome, relevant weather conditions are not forecast to exist below the cloud ceiling and visibility values mentioned in columns 2 and 3 of the item.
