Development of Airport Low-level Wind Information (ALWIN)

摘要

The Japan Aerospace Exploration Agency and the Japan Meteorological Agency (JMA) have jointly developed a novel system named 'Airport Low-level Wind Information' (ALWIN) to provide low-level wind information around airports. ALWIN provides wind information on aircraft final approach paths measured by JMA's airport-based Doppler radar and Doppler lidar. Pilots can request ALWIN information at any time from the cockpit by ACARS datalink. Operational evaluations by airlines demonstrated the effectiveness of ALWIN information for supporting on aircraft operations. Considering these favorable evaluations, operational use of the ALWIN system will begin in late 2016.
