– Ensure suitability of landing area, plan landing and land floating hull aircraft on water
            1.        assess landing area and weather conditions and formulate a plan to ensure a safe landing on water;
            2.        land aircraft at a controlled rate of descent, aligned with and above the landing direction, within a specified area, without drift, maintaining directional control and wings level and stopping within the available landing area;
            3.         minimise and control ballooning and bouncing;
            4.        perform after-landing checks correctly.
     7.               DFE7.7 – Manage abnormal or emergency situations in floating hull aircraft
            1.        identify and confirm abnormal or emergency situation;
            2.        control aircraft;
            3.         perform abnormal or emergency procedures correctly.

 2.                     Range of variables
        1.        activities are performed in accordance with published procedures;
        2.        day VFR;
        3.         cross-wind, headwind and tailwind to the limits of the aircraft;
        4.        approved floating hull aircraft;
        5.        salt and fresh waterways;
        6.          variable sea states;
        7.        confined waterways;
        8.        variable marine traffic;
        9.          maritime regulations and procedures;
       10.          limitations, such as those imposed by local noise abatement procedures or curfews;
       11.         simulated abnormal and emergency situations;
       12.          simulated hazardous weather.

 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 aircraft manoeuvrability on the water;
        5.        how the centre of resistance to lateral motion affects the operation of a seaplane;
        6.          why water rudders are not used for take-off;
        7.        how to extract information from maritime tide chart and determine the tide height and state at any specified place or time;
        8.        how the centre of buoyancy can be varied when an aircraft is on the water;
        9.          how movement of the centre of resistance affects aircraft manoeuvrability on the water;
       10.          function of a ventral fin on a seaplane;
       11.         function of float struts and bracing wires;
       12.          the requirements that apply to floats with regard to minimum number of water-tight compartments and capability of supporting the aircraft weight when compartments are flooded;
       13.      the method of detecting water inside a hull or float and how to remove the water;
       14.        the function of the 'step' at the bottom of a float or hull;
       15.        the position of the nose attitude and the 'feel' that indicates the aircraft is planning on the step;
       16.        hazards associated with excessive swells.
