Abstract: The aviation industry is a big, and growing, part of today’s world and there exist a need to find fuel and cost efficient ways of flying while also making sure that aircraft arrive on time. Optimization is an efficient tool to find optimal altitudes and speeds in order to reduce operational costs. This project explores the potentials of speed optimization together with target time constraints in order for the aircraft to also be on time. By first examining if the aircraft is expected to arrive early, on time or late, the optimal cost indices during cruise can be found in order to adapt the speeds so the aircraft can improve its arrival time. Three different methods are presented, where altitude profiles and segmentation of the cruise phase differ between the methods. Dynamic programming is used together with a time penalty function to find optimal solutions. The result shows that all methods in essence improves the arrival time. Depending on if the aircraft is expected to arrive early, on time or late, the optimization can also improve fuel consumption, while it in other cases leads to an increase in fuel consumption.
