On the ATR unfortunately the guys probably had no warning at all.
The first indication that someting might be wrong was probably the first engine quitting. Usually the right one which is used as APU and to start so the left one was probably left with a little more fuel.
Now try to figure out how far you go with - let's say 100 kg of fuel at a fuel flow of roughly 450 kg/h on one engine...
But your fuel indicators show you 1'800 kg of fuel or something like that.
These guys had a bad day.
Who is to blame? Wait for the factual final report of the ENSV. When we have all the details and the CVR transscript we will come back to this discussion
