Abstract

This work aims to develop a methodology based on wind-optimal cost index (CI) to be used in the trajectory optimization through optimal speed scheduling. Based on the accuracy of the weather forecast (wind data), the proposed method can be used for tactical and pre-departure flight planning as well as the real time speed optimization through Flight Management System (FMS). The precision of the optimal speed scheduling is proportional to the accuracy of the wind forecast. The impact of this method over a short flight is quantified to be 0.25% fuel saving compared to the wind-optimal trajectory, which shows the pure impact of wind-optimal CI. A detailed comparison between wind-optimal trajectories with fixed CI and the wind-optimal trajectory utilizing wind-optimal CI is done for a sample flight.
