To "bug smasher"
You are evidently not qualified to decide what is satisfactory or not.
If either main fuel tank in the 777 goes below 2 tonnes the crew go into a low fuel checklist. I have done this on the 777 a few times. As long as you land with reserve fuel which is typically 3 tonnes there is no problem.
The 038 did not go into the low fuel procedure. The fuel on board was actually a little more than the average 777 lands with according to a ground engineer at LHR. The fuel quantity was therefore adequate.
I've ben reading posts on PPRUNE for years but this is the first time I have been sufficiently provoked into making a post. Many of the posts on the previous 038 thread were complete drivel and the suggestions of pilot error at such an early stage of the investigation were mudslinging and should be libellous. If you throw enough mud it can stick. As for those critical of the AAIB it is amazing arrogance for some of you to think you know better about how they should be handling it.
