Abstract: This study considers the impact of the turning point location on fuel consumption for aircraft landing problem by using the point merge system. A mixed-integer linear programming model is applied for this problem. Also, vector manoeuvre is added to the model to solve any conflict before entering sequencing legs. Two different methods are compared. First, no fixed turning point is placed, allowing aircraft to make a turn anywhere on the sequencing legs. However, the problem is that it is not very applicable neither for air traffic controllers nor pilots regarding the instruction time. The second method uses constant turning points with a pre-defined distance between two successive points. The results for the second method displayed that when we increased the distance between the two following turning points, the total fuel consumption also increased by 7.35% compared to the no-fixed turning point method.
