At my club, We as a Club actually provide these, we keep them in the clubhouse, and stage them on the edge of the runway when we are flying turbines. The ones we use are like this, you put water in about 3/4 up the tank, then cap it off and fill it with an air compressor till the needle gets into the green. This extinguisher will keep you in compliance. At our Jet rally we do have a Utility vehicle loaded with water sprayer, as well as having the Fire Dept. present. But for the weekend pilots, this is the way we go.
