Scientist Dr Shubha Iyengar developed Drishti, a specialised visibility measurement system that now assists aircraft landings across India.

Advancing Indian Aviation Safety

Dr Shubha Iyengar has spent several decades contributing to the advancement of India's space and defence sectors. Her research, which gained international recognition through publication by NASA, focuses on critical infrastructure for aviation safety.

The core of her contribution lies in the development of Drishti, a sophisticated technological system designed to measure runway visibility. This tool addresses one of the most significant challenges in aviation: ensuring pilots have accurate data during low-visibility conditions.

Impact of the Drishti System

The implementation of Drishti has provided a technological framework to guide aircraft safely onto runways. By providing precise measurements of atmospheric visibility, the system helps mitigate risks associated with fog, heavy rain, and other environmental factors that obscure pilot vision during landing phases.

The deployment of this technology across various Indian airports serves several key functions:

• Improving landing precision during adverse weather conditions.
• Providing real-time visibility metrics to flight crews and air traffic controllers.
• Reducing the frequency of diversions and delays caused by visibility concerns.
• Enhancing the overall safety protocols of the Indian aviation network.

A Career in Defence and Space

Dr Iyengar's work sits at the intersection of high-level scientific research and practical national defence applications. Her expertise has been instrumental in supporting the technical requirements of India's most vital aerospace programmes.

Through her long-term commitment to these sectors, she has bridged the gap between theoretical research and the operational necessities of flight safety. The success of the Drishti system underscores the importance of specialised visibility technologies in modernised airspace management.
