Under severe weather or flow constrained areas,a new rerouting path planning model based on artificial potential field algorithm(APFA)was proposed.Considering air traffic control(ATC)program and flight performance,linear sub-fitting method was used to fit the initial rerouting path,so that the vibration and discrete points were eliminated.A curve cut-off method was used to eliminate the extra turning points,and the final flight path was generated.Simulation result shows that the length of the rerouting path flying around expanded area boundary is 532.299 km,but the length of the new generated rerouting path is 455.924 km,the path length reduces by 14.35% under the condition that the turn points aren't added.So the flow constrained area can be avoided safely and effectively by using the proposed method.
