The Hong Kong Observatory (HKO), in collaboration with the International Federation of Air Line Pilots' Associations (IFALPA), World Meteorological Organization (WMO) and International Civil Aviation Organization (ICAO), has recently published a set of three new wind shear posters and distributed them to all ICAO Contracting States on behalf of ICAO.  The three posters, entitled "Wind Shear - Their Causes", "Wind Shear - Warning and Alerting", and "Wind Shear - Pilot's  Rules", replace the old posters published by ICAO between 1982 and 1990.  The collaboration between the four organizations to publish the new posters is to promulgate the most up-to-date educational material on windshear for enhancement of aviation safety worldwide.

The wind shear posters are available in electronic form on the Observatory's website at:

They are also available on the websites of IFALPA, WMO and ICAO to facilitate their widest promulgation in the aviation community:
