  3. Abstract:
  4. A comprehensive approach is proposed to manage landing sequences and their associated trajectories for an arbitrary number of aircraft in the vicinity of a controlled aerodrome. The current approach, similar to that of "first come, first served," could consider different types of priorities as well as emergencies. The approach is especially useful to combine unstructured free-flight trajectories with structured ones during the approach phase of the flight A comprehensive cost function considers the relative size of all aircraft together with their relative speeds and flight directions. This helps optimize the amount of fuel consumption while respecting separation minima. Resulting trajectories consist of combinations of arcs and straight lines and are easy for a pilot or controller to follow. We also use the so-called genetic algorithm together with a graphical interface to solve for the optimum solution for different scenarios in an offline manner. A lookup table or an equivalent neural network might also be used to provide quick solution for real-time applications
