As the aviation sector grapples with progressive increase in air traffic and deteriorating weather conditions in the subcontinent, the Airports Authority of India (AAI) in collaboration with the India Meteorological Department (IMD) is installing Integrated Automated Weather Observing System (IAWOS) at 18 airports across the country to meet operational exigencies and mitigate economic losses.
The IAWOS provides continuous, real-time information and reports on weather conditions prevailing over an airport and disseminates weather data through a computer-generated voice message which is broadcast via radio to pilots in the vicinity of an airport. These messages are also available over a telephone dial-up service or ground data link. It consists of various meteorological sensors, data acquisition systems, processing and transmitting units.
