When distribution material is distributed over a target site on a ground surface from an aircraft, a distribution supporting apparatus offers support information to a pilot dropping the distribution material to efficiently distribute the distribution material. The distribution supporting apparatus includes: an input section to which information items on at least an aircraft velocity, an aircraft altitude, and a wind velocity are input; a computation section configured to compute a location at which the distribution material dropped from the aircraft arrives on the ground surface and a density distribution of the distribution material on the ground surface based on the information items input to the input section; and a display control section configured to display, on a display, the support information relating to the location and density distribution computed by the computation section.
