Abstract This paper evaluates the usability of two direct optimization methods: the Piecewise Linear Approximation Dynamic Programming method and the gradient-based method for a practical trajectory optimization problem based on the trajectory-based operation concept. As a practical application, the longitudinal fuel minimal trajectory of a passenger aircraft is continuously designed for all flight phases. The computational features of each method are investigated in terms of computational time, convergence to a realistic solution, and applicability for the practical model. The two kinds of optimal trajectories show a great agreement indicating that an optimal solution close to a global optimum could be obtained by the gradient-based method. The results have demonstrated that gradient-based methods have a potential to provide an optimal solution close to a global optimum with a reasonable computational time. The gradient-based method is expected to be utilized for designing a practically preferable reference trajectory toward the realization of more efficient operations in the air traffic management system.
