Abstract
The arrival management (AMAN) system is a decision support tool for air traffic controllers to establish and maintain the landing sequence for arrival aircraft. The original intention of designing the AMAN system is to improve the efficiency of air traffic management (ATM), but few studies are investigating the operational benefits of this system based on key performance indicators (KPIs) and evaluating actual data in a real-time environment. The main purpose of this paper is to propose a KPI based transferable comparative analysis method for identifying the operational benefits of the AMAN through radar trajectories. Firstly, six KPIs are established from a joint study of the mainstream ATM performance frameworks worldwide. Secondly, appropriate evaluation technique approaches are determined according to the characteristics of each KPI. Finally, a Chinese metropolitan airport is taken for the case study, and three periods are defined to form data samples with high similarity for comparative experiments. The results validate the feasibility of the proposed method and find comprehensive performance improvements in arrival operations under the effects of the AMAN system.

Increases in aviation transportation demand and air traffic flow expedite the emergence and application of novel concepts and new technologies in the civil aviation industry
Even if practice proves that the only way to achieve visible progress in performance management is to establish a transparent and objective system consisting of key performance areas (KPAs) and key performance indicators (KPIs) [3], KPIs are still considered difficult to define, assess, and quantify for arrival management (AMAN) [4] and have not been applied on a large scale to evaluate the benefits of the AMAN
This paper proposes a KPI-based comparative analysis method for quantitatively identifying operational benefits of the AMAN system through radar trajectories, proves that the KPIs are effective for the AMAN evaluation, and describes a large-scale experiment in a real-time operating environment
Summary
Increases in aviation transportation demand and air traffic flow expedite the emergence and application of novel concepts and new technologies in the civil aviation industry. To manage arrivals to a multi-runway aerodrome or locations with multiple dependent runways at closely proximate aerodromes, and to efficiently utilise the inherent runway capacity [1], arrival management (AMAN) system, a.k.a. aircraft arrival management system (AAMS), is created and applied as a decision support tool (DST) for air traffic controllers (ATCOs). The same is true in previous evaluations on operational benefits of the AMAN system. They are almost implemented through modelling, simulation, and subject matter expert surveys [2]. Whether an AMAN meets the expectations set for is usually regarded as a matter of subjective opinions and reflected by the feedback from ATCOs and other users
