 3.                     Underpinning knowledge of the following:
        1.        differences between a seaplane, floatplane, flying boat (floating hull) and amphibious aircraft;
        2.        aircraft performance with respect to:
               1.          design features for seaplanes, floatplanes and floating hulls; and
               2.         the differences between an aircraft that is fitted with the feature and the same type of aircraft that doesn't have the feature;
        3.         how to interpret Beaufort scale readings and ascertain wind velocity;
        4.        how movement of the centre of buoyancy affects amphibious aircraft manoeuvrability on the water;
