If it is dark and you do the routine drain of the tanks, can you you really tell how much water you have removed?
I’ve only ever had at most an inch or so (3 cm) of water in the sample I’ve drained, but I have heard of it being much more. In the dark it could be hard to tell the difference between the water and the av fuel, so maybe there was residual water that made the engine splutter on take off.
Plus, I was told to rock the wings before drawing the fuel, as that would shake free any water condensed inside the tanks of a partially fueled plane, and let me get rid of it, rather than have it shake loose and get into the fuel mixture during run up and takeoff.
I would have thought all that would do is mix the water that had already settled with the fuel !?
