Which airport became the first in India to operationalise a satellite-guided helicopter approach procedure?
Answer: Option
Explanation:
HAL Airport in Bengaluru became the first airport in India to operationalise a satellite-guided helicopter approach procedure on August 7, 2026. The procedure uses Required Navigation Performance Category H (RNP CAT H), a specialised satellite-based navigation system designed specifically for helicopters. Developed by the Airports Authority of India (AAI), it was validated by HAL test pilots and approved by the Directorate General of Civil Aviation (DGCA). The system reduces helicopter approach time from around 12 minutes to approximately 4 minutes and enables accurate flight paths around terrain and urban obstacles. It is particularly useful for air ambulance and search-and-rescue operations.

Which institute developed the E-Eye portable device for detecting toxic metals and bacteria in water?
Answer: Option
Explanation:
IIT Guwahati researchers developed E-Eye, a low-cost and portable optical sensing device for rapid on-site detection of water contamination. The device can detect heavy metals such as arsenic, lead, iron and chromium, along with fluoride and E. coli bacteria. It operates using the Beer-Lambert law and measures colour changes in chemical reactions to estimate contaminant concentrations. The device costs around ₹3,500, with an operational cost of about ₹2 per sample. Its performance is comparable to standard laboratory instruments, making it particularly useful for water-quality monitoring in rural areas.
