  • The runway visual range affected by fog and so on is one of the important indicators to determine whether aircraft can take off and land at the airport or not. In the case of airports where transportation airplanes are operated, major weather forecasts including the runway visual range for local area have been released and provided to aviation workers for recognizing that. This paper proposes a runway visual range estimation model with a deep neural network applied recently to various fields such as image processing, speech recognition, natural language processing, etc. It is developed and implemented for estimating a runway visual range of local airport with a deep neural network. It utilizes the past actual weather observation data of the applied airfield for constituting the learning of the neural network. It can show comparatively the accurate estimation result when it compares the results with the existing observation data. The proposed model can be used to generate weather information on the airfield for which no other forecasting function is available.

  • Due to the lack of a noise and vibration survey for military air bases, noise and vibration are not taken into consideration for new installations, which has resulted in a number of problems, including the separation of tiles. Furthermore, it is not possible to establish appropriate counter-vibration plans to minimize damage resulting from vibration on structures, since no standard is in place when location for residence areas, including military quarters, is determined. In this context, this research includes a noise and vibration survey, on which basis a quantitative evaluation model for vibration of structure by aircraft noise is generated, as well as through linear regression analysis, and suggests installation standards by purpose of structure, minimizing the damage due to noise and vibration, and establishing appropriate counter-vibration plans for future installation and repairs of on-base structures in the military bases.

  • In this paper, we reviews the need and contents of aerodrome control simulator for air traffic controllers' training. In the view of managing the aviation safety, the departure and landing phases of aircraft are very important, because more than 60% of aircraft accidents and incidents have occurred in the take-off and landing phases. According to the benchmark each as practice type, simulation device and fidelity of reality of the air traffic control simulator, we have evaluated the implementation level of the domestic air traffic control simulator and checked up the current simulator's problems through the air traffic controllers' survey. Therefore, we suggest to the direction of developing a HI-FI simulator for aerodrome controllers.

  • As ground air traffic control at the airport is one of the most important tasks in air transport, attention to the development of a related simulator has expanded all around the world. For this reason, this research describes the characteristics and advantages of this advanced aerodrome traffic control simulator, developed in South Korea, as well as its linkage with A-SMGCS, which is planned to be developed in the future. One of the characteristics of this simulator is that it is possible to train an air traffic controller independently, especially under various conditions such as in different weathers and normal or abnormal circumstances. Therefore, this aerodrome traffic control simulator, through the comprehensive training under various conditions, will contribute to aviation safety and airport capacity enhancement training.
