Attention is drawn to the necessity of using a positivemethod, such as
suitablewater-detecting paste or paper, in testing for thepresenceof free
water since sensory perceptions of colour and smell, if used alone, can
be quitemisleading. In the case of turbine fuels, attention is also drawn to
the necessity ofwatching for signs of cloudiness or other indication of the
presence of suspendedwater dropletswhichwill not necessarily be detected
by a positivemethod.
All fuel shall be strained or filtered for the removal of freeor suspendedwater
andother contaminatingmatter before entering the aircraft tanks. Attention
is drawn to the special standards of filtrationwhichmay be specified by the
manufacturers of certain types of engines e.g. turbine engines anddirect-
injectionpistonengines.
