In this case the crew used all the fuel before making the decision they had to land. In the Mildura situation the first jet to land 'may' have had over an hour of fuel left on board, but still busted the minima, and the company made sure the actual fuel logs and state were not released to the ATSB, the ATSB only had access to the dispatch calculation and a statement 'the captain routinely uplifts more fuel'. Prior to diversion the first crew to land there stated in the report that they had enough fuel to cover a TEMPO on arrival at Mildura, however they basically went straight into the approach 'due fuel' and landed. The ATSB even calculated that if they had held at altitude they could have still returned to Adelaide at 0955 almost 10 minutes after they had landed in Mildura, and that was based on minimum fuel uplift from Sydney. I don't have to tell you which airline that was, it was not SQ, and I would consider the lack of compliance with the ATSB on the issue as substantial or the ATSB has chosen not to release such data due to the implications with regard to CAR 257. Now does that constitute an airline having its arse covered or not...
