In order to understand the motion characteristics of amphibious aircraft planing in head waves, in this paper, the Chinese numerical tank-Cartesian grid finite difference method was used to study the planing motion response characteristics of an amphibious aircraft in waves under different wave conditions. The effects of wavelength and wave height on heave and pitch response of the aircraft and the vertical overload of mid-ship and stem were summarized. Based on the step-by-step method, the Navier-Stokes equation was discretized in space. The immersed boundary method was used to capture the boundary of complex objects and accurately simulate its large motion. At the same time, the THINC/SW algorithm was used to effectively simulate the violent motion of free surface. The results show that the wavelength and wave height have a great influence on the planing motion response of the amphibious aircraft. With the increase of planing speed, the pitch resonance wavelength increases, and the heave resonance wavelength decreases first and then increases, while the linear correlation between the heave and pitch response of the aircraft, the vertical overload of the mid-ship and stem and the wave height will also be weakened.
