“…At present, much attention is still paid to large-scale aircraft noise modelling [6,7] and mapping with an emphasis on aircraft flight performance, rather than the effects of built-up obstacles on noise attenuation [8][9][10]. While many prediction tools mainly focus on the noise from taking offs and landings, noise mapping tools for aircraft taxing have also been developed [11].…”

“…Noise contours around airports are used as planning and evaluation tools, and as a component of long-range efforts by local, regional or national authorities. Aircraft noise contour assessment is a complex procedure due to the different route schemes, procedures, aircraft and types of engine in operation around an airport (Zaporozhets & Tokarev, 1998). The usage of a reliable, validated, and updated noise model is an essential step for producing accurate noise contours for the purposes of environmental noise analysis.…”

One of the biggest obstacles to the building of new airports and expanding runway capacity is environmental concerns, especially noise. In this paper, we review what has been previously studied in the literature concerning the noise reduction problem around airports from the Air Traffic Control (ATC) perspective. In order to facilitate the knowledge of the current situation, a regulation summary from the USA and EU is provided. We mainly focus our research on operational procedures, since they are one of the easiest improvements nowadays for reducing the impact of noise around airports.Moreover, the paper sums up the modelling, monitoring and simulation tools related to noise at airports proposed in the literature. Finally, special care is taken to review the optimization tools, the objective of which is to take into account the noise problem in order to help, or propose alternatives, to reduce its impact from airport operations.

“…This paper uses the basic principles of aircraft noise modeling. The cost function may be chosen as any of the usual aircraft noise indices, which describes the effective noise level of the aircraft noise event [22,23]. This study is limited to minimize the maximum noise level using a semi-empirical model of jet noise [5,6,[24][25][26].…”

“…It is necessary to examine the potential for modified approach procedures that can benefit both airlines and the communities. The International Civil Aviation Organization (ICAO) has recognized the potential benefits of using advanced flight guidance technology to reduce the impact of aircraft noise [2,23,26,42]. ICAO charged its Noise Abatement Operating Measures Subgroup (NAOMSG) with the following tasks:…”

Introduction Flight path optimization is designed for minimizing environmental impacts of aircraft around airports during approaches. The main objective of this paper is to develop a model of optimal flight paths taking into account jet noise, fuel consumption, constraints and extreme operational limits of the aircraft in approach. Materials and methods Optimal control problem combining aircraft flight paths, noise and fuel consumption is modeled and solved. Outputs, algorithm efficiency and their ability to be interfaced with the in-flight management system, respecting airspace system regulation constraints, are analyzed. Measurements of aircraft noise are carried out around Saint-Exupery Lyon International Airport for one year, and INM simulations are performed. Results and conclusion A two-segment approach is considered as an optimal trajectory. Aircraft alignment on the runway axis with a slope between 3 • and 4.5 • during the last approach segment is obtained and the descent rate is about 1060 ft/mn. This particularly characterizes the continuous descent approach having the potential to reduce noise emission by −4 dB and fuel consumption by −20 % to −10 % during the approach. Because of the suggested trajectory, optimized noise levels are less than the measured and INM values given by the empirical trajectory. Optimal trajectory consumes less than the standard one; and it can be integrated in the aircraft FMS and the autopilot system. This is one of
