First, the features of discrete Moore neighborhood in two dimensions are analyzed and it is expanded to three dimensions. Tables of probability of horizontal and vertical conflict risk are established, which could calculate the three- dimension risk. At last, the same simulation data is calculated by two methods, which include horizontal and vertical conflict risk separately and simultaneously. The simulation results illustrate the expanded Moore neighborhood method could judge the free flight conflict risk rapidly, especially conflict risk is calculated horizontal
