I find it distressing and incomprehensible that given months, not moments, to consider the facts, the Sheriff Principal has come to this conclusion. He chose not to concentrate on the fact that the EC135 model of helicopter has a history of faults with the caution advisory display, specifically a history of erroneous or spurious fuel indications, amongst other technical problems such as contamination of the fuel tanks, issues still never fully resolved by the manufacturer.
I have never flown the type involved, but bearing in mind the above - and assuming that any pilot of the type is aware of these facts - would it not be prudent to fly with the maxim "if in doubt chicken out"?
