Well, water detection tablets with the diddy syringe thing for the Jet A1 bowser, but a swill in a jar and a "Bright and Clear" check for the AVGAS.
I believe it's something to do with the lower tolerance for dissolved water in Jet A1 that the burners don't like, whereas a 1930's carburetor
and Champion's finest can still make a bang with a higher ppm of dissolved water.
The Shell man tests both fuels for water with his kit but as users we do as above. Should we be using tablets on the AVGAS?
Very interesting photos by the way.
