The need for increasing air traffic capacity motivates 4D trajectory planning concept. In order to generate conflictfree 4D trajectories, we introduce a new concept based on light propagation modeling algorithm. This algorithm is a wavefront propagation method that yields a natural solution for the path planning problem specifically in the case of air traffic congestion. We conclude this paper with numerical experimentation of our approach on a simplified (2D + time) test problem.
