HAL Airport gets satellite-guided navigation system for choppers

HAL Airport in Bengaluru, India, has become the first airport to implement a satellite-guided precision navigation system specifically for helicopters, the state-run aircraft manufacturer announced on Friday. Known as the Required Navigation Performance – Category H (RNP CAT H) helicopter approach procedure, this system was developed by the Airports Authority of India (AAI), tested by HAL test pilots, and approved by the Directorate General of Civil Aviation (DGCA).

This milestone is significant for India's aviation sector, as it enhances helicopter safety, efficiency, and accessibility. HAL chief Ravi K expressed optimism, stating that the capability will set a benchmark for similar procedures at airports nationwide. The RNP CAT H system enables helicopters to fly optimized paths, facilitating all-weather access and safe navigation through terrain and urban obstacles.

By reducing the approach time from 12 minutes to approximately four minutes, the system boosts operational efficiency and airspace capacity. It also allows for seamless integration of rotary and fixed-wing aircraft, reduces noise pollution over cities, and provides faster, safer routes for critical missions like air ambulance and rescue operations. HAL Airport, which handles nearly 50 helicopter movements daily, has effectively closed a longstanding gap in India's aviation infrastructure with this launch.

The airport serves HAL, the National Flight Test Centre (NFTC), the Centre for Airborne Systems and Aircraft (CABS), and the Aircraft and Systems Testing Establishment (ASTE), among others. It is also a hub for VIP movements.
