The Problem: Fog and Flight Operations Winter travel often brings a familiar frustration: flight delays or diversions due to heavy fog. When visibility drops, pilots cannot see the runway clearly, drastically increasing the risk of accidents. To mitigate this, India spent years importing highly expensive visibility systems from foreign manufacturers.

The Innovator: Dr. Shubha Venkatesh As a leading aerospace scientist at the National Aerospace Laboratories (NAL) in Bengaluru, Dr. Shubha Venkatesh envisioned a permanent, indigenous solution rather than relying on imported technology.

The Solution: ‘Drishti’ After years of rigorous research and development, Dr. Shubha and her team developed a 100% Made-in-India runway visibility system named ‘Drishti’.

Drishti is a highly advanced transmissometer. It precisely calculates the visual range on a runway during severe fog or heavy rain, instantly relaying this critical data to Air Traffic Controllers and pilots to ensure safe landings.

The Mega Success (September 2026 Milestone) Recent reports from the past month confirm that the ‘Drishti’ system is now successfully installed and operational across more than 100 aviation locations in India.

Not only is this system significantly more cost-effective than its foreign counterparts, but it also meets rigorous global precision standards. Today, every safe landing through dense fog at major Indian airports owes a debt to Dr. Shubha’s groundbreaking work.

The Takeaway This milestone is a powerful testament to indigenous engineering. It proves that local talent can build world-class, life-saving aviation technology.
