In order to improve the automation level of the design of flight path in terminal airspace,the approach and departure routes are studied. According to the optimization of the independent route,the search method which the horizontal direction is prior than the vertical direction is proposed,choose the optimum of the horizontal profile efficiency as the objective function,and make the vertical profile meet the demands of the optimum in the climb / descent profile. Extend the route through the angle to reduce the search space,achieve the optimization of route network in the 3D. Example results show that to ensure the safety and economic efficiency of the route at the same time,the algorithm is stable,and the operating efficiency is improved significantly.
