Abstract. A flight plan is a prescription for a flight on a specified aircraft route. It must ensure two safety-critical conditions: fuel adequacy, to ensure that the aircraft can safely reach the destination, and compliance with air traffic control requirements, to minimise the risk of midair collision. In addition, flight planners normally wish to minimize flight cost through the appropriate choice of path, height, and speed, and by loading the minimum necessary fuel on board.
Path finding algorithms based on A* search on a network of airway points have been used for producing approximate optimal flight plans by computers. However, the need for more efficient and effective algorithms brought recently the attention on some specific features of flight planning that have been poorly addressed by these algorithms. In the talk, we will review our work on path finding algorithms to deal with flight planning features, such as the resource dependency structure of costs, the constraints, the large amount of data, and the presence of free route airspaces, where flight trajectory do not need to adhere to an underlying network.
