The wooden floats for the micro-light-airplane were designed after Cresswell Walker and built by hand. MAXAIR DRIFTER installing these floats succeeded in a series of the water taxing test. It was necessary to secure the safety of the flight test, (a) the load factor of taking off from the water / landing on the water, (b) the load above the water surface in the various condition, (c) the local pressure of the hull / the body surface of the float, and (d) the pressure distribution of the hull of the float were calculated following to Air Worthiness Regulation division second. As the result, the calculation models simulated the structural strength of the wooden floats were introduced, and there were clarified that the material strength of the wooden floats exceeded the results in stress. Furthermore, the calculating procedures of the weight center and the fore-and-aft inertia radius of the airplane equipped with the floats were mentioned.
