Abstract: This paper aims to propose a novel approach to determination of way points position on sequencing leg for point merge system. This research uses the Base of Aircraft Data to analyze the flight efficiency. Although it is not a general rule, it can be said that there is a tendency in practice to design the waypoints in the sequencing leg at equal distances from each other. In general, essentially equidistant waypoints are designed to facilitate the adaptation of airspace users (both pilots and air traffic controllers). However, it does not seem possible to say that this tendency always gives the most appropriate and optimal results in terms of flight efficiency. A scenario that includes four different cases was ideated and was resolved to discover the potential benefits and/or drawbacks of equidistant and non-equidistant interspace of waypoints. The comparison results of equidistant and non-equidistant interspace show that the average reduction of 9,5 percent of total flight time; 12,5 percent of total flight distance in favor one of a non-equidistant interspace, which is Case-4. Moreover, the Case-4 could be a promising solution for sequencing aircraft conveniently in terms of a first come first service (FCFS) rule.
