New Edition of Windshear Booklet is Now Available

The booklet “Windshear and Turbulence in Hong Kong – information for pilots”, jointly published by the International Federation of Air Line Pilots' Associations and the Hong Kong Observatory in 2002, has recently been revised to incorporate the latest developments of the windshear and turbulence alerting services for the Hong Kong International Airport. Among other things, this third edition of the booklet covers new topics including the differences between windshear and turbulence, a LIDAR (LIght Detection And Ranging) case demonstrating the transient and sporadic nature of windshear, and changes in the phraseology of warnings and alerts of windshear and turbulence since the last edition.

Interested readers are welcome to download an electronic copy of the booklet at the following address:
