HAL airport becomes first in India to operationalise RNP CAT H helicopter approach
HAL airport in Bengaluru has become the first in India to implement the RNP CAT H helicopter approach procedure. This satellite-guided navigation system improves safety and efficiency, significantly reducing approach times for helicopter operations.
Why it matters
This technological advancement sets a new safety benchmark for helicopter navigation in urban environments and critical emergency services across India.
The Hindustan Aeronautics Limited (HAL) airport in Bengaluru has become the first airport in India to operationalise the Required Navigation Performance – Category H (RNP CAT H) helicopter approach procedure.
RNP CAT H helicopter approach procedure is a satellite-guided precision navigation system designed exclusively for helicopters.
Developed by the Airports Authority of India (AAI), validated through flight trials by HAL test pilots, and approved by the Directorate General of Civil Aviation (DGCA), this approach allows helicopters to fly highly accurate optimised paths, enabling all-weather access while safely navigating terrain and urban obstacles. The procedure reduces the approach time to HAL airport from 12 minutes to about four minutes.
“This capability enhances the safety, efficiency and accessibility of helicopter operations, and establishes a benchmark for similar procedures to be implemented in airports across the country,” said Ravi K., CMD, HAL.
