question.
ignoring all the possibilities of any issues with fuel gauges (and I thought the known issue was with the main tank gauge or is it all three? and was it not about them over-reading when subjected to water contamination?), if they started with full tanks (which we are lead to believe?), then surely an experienced EC135 pilot would have a good idea what the typical range (in hours/minutes) are for this 'copter?
if we ignore the fact he crashed, and assume he had the Xfer pumps on, and landed safely, just how much fuel would have been left? main tank would be empty by then and I'm guessing the supply tanks would be significantly down from full?
if we are saying that nighttime min fuel is 90Kg's, then he was going to be well under that no matter what, anybody want to put a number to this?
