WTWS Products

The Hong Kong Windshear and Turbulence Warning System (WTWS) research and development program, previously known as the Operational Windshear Warning System (OWWS) program, successfully concluded in January 1998. The Hong Kong Government accepted the WTWS system on schedule in July 1997.
Hong Kong International Airport opened its new international airport at Chek Lap Kok (CLK) in July 1998. The WTWS system has been operating since the airport opened. The WTWS is providing windshear and turbulence alerts to pilots arriving or departing the airport when conditions warrant. Input from pilots and controllers is being used to evaluate and tune the system.
