Pilots are sometimes not provided with sufficient information to avoid go-arounds or other operational disruptions that result from low-level wind disturbances. We identified issues with existing windshear alerting systems and developed three types of airport low-level wind information systems to enhance pilot situational awareness of wind conditions by providing landing aircraft with quantitative and visualised wind information for ultimately mitigating air service disruptions due to low-level wind disturbances. The three systems, Airport Low-level Wind Information (ALWIN) and Low-level Turbulence Advisory System (LOTAS), both of which use Doppler radar/lidar, and Sodar-based Low-level Wind Information (SOLWIN), which uses Doppler SOnic Detection And Ranging (SODAR), have different costs and capabilities that allow the most cost-effective system to be selected for an airport according to its scale and local weather characteristics. This paper presents the operational concepts of our newly developed airport low-level wind information systems and describes their validation.

新型机场低空风信息系统的运行概念与验证

有时没有为飞行员提供足够的信息来避免因低空风扰而导致的复飞或其他运行中断。我们发现了现有风切变警报系统的问题，并开发了三种类型的机场低空风信息系统，通过为着陆飞机提供定量和可视化的风信息来增强飞行员对风况的态势感知，从而最终减轻由于低空风造成的空中服务中断干扰。这三个系统，机场低空风信息 (ALWIN) 和低空湍流咨询系统 (LOTAS)，均使用多普勒雷达/激光雷达，以及基于 Sodar 的低空风信息 (SOLWIN)，使用多普勒 Sonic检测和测距（SODAR），具有不同的成本和能力，可以根据机场的规模和当地天气特征为机场选择最具成本效益的系统。本文介绍了我们新开发的机场低空风信息系统的运行概念并描述了它们的验证。
