        then the pilot in command of an aircraft must nominate a destination alternate aerodrome if the ETA is during the period that:
(c) begins at the forecast commencement of relevant weather conditions at the planned destination aerodrome; and
(d) ends at the forecast ending of the relevant weather conditions.
       (3) If the forecast for the planned destination aerodrome required by subparagraph 7.02 (1) (a) (ii) is not available then the pilot in command of an aircraft must nominate a destination alternate aerodrome.
       (4) Subsections (1) and (2) do not apply if the pilot in command is operating an aircraft under the VFR by day within 50 NM of the departure aerodrome.
       (5) Subsections (1) and (2) do not apply if:
(a) relevant weather conditions exist; and
(b) the pilot in command ensures that sufficient fuel is carried to permit the aircraft to hold at the planned destination aerodrome until the end of the period mentioned in subsection (1) or (2), as the case requires.
       (6) Subsections (1) and (2) do not apply if:
(a) relevant weather conditions are forecast to occur on an intermittent or temporary basis; and
(b) the pilot in command ensures that sufficient fuel is carried to permit the aircraft to hold for:
 (i) 30 minutes — when the forecast is based on a change indicator of INTER; or
 (ii) 60 minutes — when the forecast is based on a change indicator of TEMPO.
       (7) For subsection (6), if a forecast contains multiple change indicators of INTER or TEMPO, the fuel for holding that is required under paragraph (6) (b) must be that for the most limiting requirement.
       (8) For subsections (1) and (2), if a forecast includes the change indicator BECMG:
(a) where the weather conditions within the BECMG element of the forecast represent a deterioration in any of the weather elements within the preceding element of the forecast — the change indication is to be applied from the start of the forecast BECMG period; and
(b) where the weather conditions within the BECMG element of the forecast represent an improvement in all of the weather elements within the preceding elements of the forecast — the change indication is to be applied from the end of the forecast BECMG period.

8.05 Destination alternate aerodromes — navigation
       (1) The pilot in command of an aircraft must nominate a destination alternate aerodrome if a flight is an IFR flight by night to a planned destination aerodrome that is:
(a) not served by an IAP; or
(b) is served by 1 or more IAPs none of which the pilot in command is able to conduct.
       (2) For a VFR flight by night, the pilot in command
