Indigenous Visibility Measuring System, DRISHTI, installed at IGI Airport

Jul 21, 2015 11:11 IST

An indigenously designed and developed Visibility Measuring System DRISHTI was installed at the Indira Gandhi International (IGI) Airport, New Delhi on 20 July 2015.  The CAT III B IGI Airport, New Delhi, is now the first Airport in the country to have 10 indigenous systems operating in all its three runways.

The system developed by CSIR-National Aerospace Laboratories (CSIR-NAL), Bengaluru will be used for reporting the runway visual range, which is a critical parameter for safe landing and take-off of aircraft in poor visibility conditions (<25 to >2000 meters).

Drishti system
• It is very cost-effective and is a mandatory system required at all airports as per International Civil Aviation Organisation (ICAO) and World Meteorological Organisation (WMO).
• The complete system is engineered in such a way to enable easy installation and maintenance.
• It can perform health monitoring of the system through web enabling from Bengaluru itself.

Earlier, CSIR-NAL and India Meteorological Department (IMD) signed a partnership agreement to jointly execute a mega project for installation of nearly 70 Drishti systems, at various Airports of the country.

The Drishti field site system is completely designed and fabricated at CSIR-NAL. IMD has established the dual mode Landline and Wi-Fi communication along with multiple displays at Air Traffic Control Room and Approach Radar Room.

The data from Drishti systems at IGI Airport can be viewed on a single screen at ATC, which would aid the MET officer to easily report visibility data to pilots.
