10 pages of disagreements about how the fuel system works - uphill syphoning , swirl, pump types, CoG attitude changes, ltrs / kgs water in capacitive fuel senders, confusion about wether one engine should stop first or both might stop at about the same time - leads me to beleive that the understanding amongst the population of 135 pilots is clearly appropriate (not) - carry on.
Anyone with a clear understanding of the system care to explain what scenario leads to a double engine stoppage ? Just incase there is any 135 pilot out there who doesn't know..
What are the combinations of possible failure with 12 hoses 6 fuel pumps and 4(?) non-return valves - does the pilot need to understand that? No - not if it's all working properly i guess.
Remember the A109 in Wales because of the misunderstanding of a transfer pump failure?
