With improving navigation systems, commercial aircraft can take more flexible routes. However, routes of the aircraft still have several operational restrictions, such as sector boundaries. This paper shows the trajectory optimization method for arrival aircraft considering the constrains due to the sector boundaries. The obstacle layout method is employed to set the constraints. To express the sector boundaries, the obstacles are set to the trajectory optimization by referring to radar data. Numerical simulations are conducted to show that the trajectory optimization method with the obstacle layout method can calculate the optimal arrival trajectory considering the constraints due to the sector boundaries.
