A method for controlling propulsion of an aircraft across a water surface comprising:

• actuating an electronic controller connected to a water propulsion system of an aircraft having a flotation surface, the electronic controller generating a plurality of control signals to control the water propulsion system of the aircraft, the aircraft further including an aircraft engine to control airborne flight, and a flight control system;
• and
• actuating the water propulsion system having a propulsion thruster to control movement of the aircraft across a water surface.
