How Indigenous Drishti Technology Keeps North India Flying Safely Through Dense Winter Fog

Every winter, dense fog blankets North India, severely challenging aircraft operations. At Indian airports, an indigenous technology called Drishti, developed by the National Aerospace Laboratories, Bengaluru, plays a critical role by precisely measuring runway visibility, enabling hundreds of safe landings and take-offs during low-visibility foggy conditions. NDTV’s Science Editor Pallava Bagla gives you close look at the technology.
