Our company policy is we can go as long as the destination visibility is above the landing minima. If this can’t be complied with we must nominate another destination airport that has a visibility above landing minima. As the flight progresses and if the visibility improves at the scheduled destination above the landing minima, then a reclearance operation is perfectly OK. Can’t see a problem with DJ departing with destination less than landing minima if they were doing it in accordance with their SOP’s. Maybe they had a flight plan and fuel for Adelaide. Maybe they were hoping they could refile for Melbourne once approaching TOD. Maybe we will just have to ask the crew.
