water solubility in Jet A
the problem arises from the decreased solubility of water in Jet as the temp drops. Similar to loading too much sugar in a coffee or tea. It can only dissolve so much then precipitates out into visible water. As the fuel chills off in flight the water can be sufficiently cooled to cause precipitation. Can also happen in drums moved to a cold area after filling.
Water detecting paste ( green stuff that goes purple ) only works on water you can basically see and should only be used on avgas. Shell water detector or similar should always be used including on daily's
