LGBI gets visibility system

Guwahati, May 6: The Lokpriya Gopinath Bordoloi International Airport in Borjhar here today installed an advanced visibility measuring system which will aid safe landing and take-off of flights.

An Indian meteorological department official said Drishti - an indigenous visibility measuring system - is used for reporting the runway visual range, which is a critical parameter for safe landing and take-off of aircraft in poor visibility conditions (less than 25 to less than 2,000 metres).

The system was installed at the LGBI Airport as part of the first phase of the installation of 20 such systems in 10 airports across the country.

"The system has been indigenously designed and developed by the CSIR-National Aerospace Laboratories (CSIR-NAL), Bangalore.

Six more such systems have been planned in the northeastern states in the next phase of installation," the official said. "It will help pilots to land and take off aircraft safely, " he added.

The official said Drishti is a cost-effective and mandatory system required at all airports according to the guidelines of the International Civil Aviation Organisation (ICAO) and World Meteorological Organisation (WMO).

The system has been engineered in such a way so as to enable easy installation and maintenance. Drishti is the only indigenously built transmissometer of its kind and its cost is just one-third of the imported transmissometers and is considered more accurate.

The Drishti system is completely designed and fabricated at CSIR-NAL.

The IMD has also established a dual mode landline and Wi-Fi communication along with multiple displays at the air traffic control room and approach radar room in the airport.

CSIR-NAL and the IMD had signed a partnership agreement to jointly execute the project for design, development and operation of the instrument last year. It is an example of the Make in India initiative of the Centre.
