A uniform model for conflict prediction and airspace safety assessment for free flight is presented. This model is inspired by classical electromagnetic theory. The free flights in the airspace are considered as charged particles in this model. By dividing the airspace into elementary grids, the electric static potential of the grid’s vertices is then used to predict the conflict between trajectory pairs. Furthermore, the average of vertices’ potential of grids can be interpreted as the safety level, in terms of conflicts between free flights, of the whole airspace. The application of the proposed model is not limited to free flight scenario, however, it can be applied in general aviation airspace and/or UAV operating airspace without difficulty. Two dimensional version of the proposed model is presented in this article. And numerical simulations show the effectiveness of the proposed model.
