Officials from the India Meteorological Department (IMD), Pune and National Aerospace Laboratories (NAL), Bangalore – have installed weather equipment at Kannur International Airport. The equipment consists of RVR (Runway Visual Range) system and AWMS (Aviation Weather Monitoring System), installed at the 25 end of the runway. These devices collect real-time data on visibility, temperature, pressure, wind and relative humidity.
The RVR system installed, known as Drishti, is a first of its kind visibility measuring system at airports in Kerala and CSIR-NAL is the only organisation to have made it in the country.
The AWMS has also been indigenously developed under a partnership between CSIR-NAL and IMD. It measures wind speed, wind direction, pressure, temperature, dew point and relative humidity. The integrated system of Drishti and AWMS meets all the requirements of the International Civil Aviation Organization (ICAO). It has been fabricated with a unique 10 metre mast to house the weather sensors, which will aid in easy servicing and maintenance. Since both these systems have been indigenously developed, they are cost effective compared to imported systems.
Once the airport is operational, meteorological data will be examined and verified by IMD officials stationed in the ATC (Air Traffic Control) building, before being passed on to the air traffic controllers. This real-time weather information will be relayed to pilots to assist in safe landing and take-off.
Officials from both NAL and IMD were present for the installation and testing of the equipment.
