Optimization of Approach Trajectory Considering the Constraints Imposed on Flight Procedure Design

Abstract

Due to recent growth of air traffic demand, inefficiency in flight is becoming a more and more important issue. However present flight trajectory is not completely optimized because of the existence of difficulties in flight procedure design. This paper describes a method to optimize the approach procedure in terms of fuel efficiency. In proposed method, route is parameterized by position of each waypoint and speed above them. Then assuming constant acceleration and point mass model, total fuel consumption is calculated. Optimization is conducted with constraints imposed upon flight procedure design by using genetic algorithm. We applied the method to approach procedure to a real airport and more efficient trajectory is obtained.

Importance of a Letter of Operational Coordination Agreement (Loca) Between Airnav and Police

“…In the absence of an agreement between the police and the ATS Unit, an incident like this might happen again because there is no governing regulation such as a Letter of Operational Coordination Agreement (LOCA) or memorandum of understanding. [9] With the level of traffic density every day that continues to increase at Juwata Tarakan International Airport and the Tarakan Approach area, we can conclude that a control unit has full responsibility for traffic operating on the ground and air area. In its service, the coordination of each -each trafficrelated unit must be fulfilled, because coordination is one form of responsibility of a control unit for ensuring the safety and comfort of flight traffic.…”

“…[1] And also based on the Regulation of the Minister of Transportation of the Republic of Indonesia PM 65 of 2017 concerning Civil Aviation Safety Regulations part 170 Chapter II Coordination Procedures which reads "The aviation traffic service provider unit must make a Letter of Operational Coordination Agreement (LOCA) with the adjacent and other related traffic service provider units which include coordination procedures and transfer of control of aircraft from one unit to another".

Hasegawa et al (2015) present optimization method to plan approach procedure in terms of fuel efficiency. The route is parameterized by position of each waypoint and speed above them.…”

Optimizing Energy Consumption in Transportation: Literature Review, Insights, and Research Opportunities

“…The optimization problems under consideration include objective functions of fuel cost minimization, total flight time minimization, and nitrogen emission minimization. Hasegawa et al [174] considered trajectory optimization with several realistic constraints. Pursuing the minimization of fuel cost, a GA algorithm is used to solve the problem.…”
