Performance of Civil Aviation Communication Network in Yemen: Study, Analysis and Processing

Civil Aviation Communication Network in YEMEN suffers from various problems which have negative effects on Air Traffic. As the air traffic grows, the ability to accommodate these traffic fails. This may lead to hazardous consequences. In order to enhance the quality and performance of the available network, three studies were performed. Unfortunately none of these studies was flexible enough to encounter the on-going growth of air traffic. Those studies focused on a detailed analysis of the Communication Network that included all point and air routes. The results of those studies led the researcher to find out some solutions to overcome the problems that this network is facing and enhance the performance of ground to air communication though all areas across the air space owned by Republic of Yemen. One of the solutions offered is to redistribute the available ground stations (GS). Another solution is to create new ground station in Al-Mukalla. Moreover, the researcher used simulation program (Radio Propagation and Virtual Mapping) to study all stages that Civil Aviation Communication Network have gone though. The result of this study emphasized on modifying flight levels and air routes in some points to levels higher than (FL280). Consequently, flight level (FL510) was applied to the eastern regions and the level (FL400) to part of the northern region across the borders between Yemen and Saudi Arabia.
