Route Planning for Light-sport Aircraft in Constrained Airspace

The airspace for the activities of light-sport aircraft in Taiwan is strongly restricted due to mountainous terrains and populated areas. This study intends to investigate the feasible sky-lanes for light-sport aircraft by minimize the impact to populated area and the threats from terrain obstacles to the aircraft. The terrain obstacles and populated area is considered and segmented in the two-dimensional structure through the graph theory. The shortest path problem between the aerodrome and the training area is established to minimize the impact to population and threats to the aircraft. The Dijkstra algorithm is adopted to resolve the planning of feasible sky lanes and gives the possibility of the augmentation of airspace for the activities of light-sport aircraft.
