Abstract(s)
The main purpose of this paper is to develop a trajectory optimization method to
generate optimal trajectories that minimize aircraft total trip time between the initial and final
waypoint in predefined 4D waypoint networks. In this paper, the 4D waypoint networks only
consist of waypoints for climb, cruise and descent approach without the take-off and landing
approach phases. The time optimal trajectory is generated for three different lengths of flights
(short, medium, and long-haul flight) for two different commercial aircraft and considering zero
wind condition. The Results about the presented applications show that by flying a time optimal
trajectory, which was found by applying a single source shortest path algorithm (Dijkstra’s
algorithm), can lead to the reduction of average travel time by 2.6% with respect to the total trip
time.
