Belagavi and 23 other Airports to get equipped with Global Navigation satellite system by year end

The Airports Authority of India (AAI) plans to equip 24 more airports by the end of this year with the global navigation satellite system (GNSS), whose approach procedures enable flights to land at airports despite poor visibility due to heavy rain or fog. As many as 45 Indian airports will now have approach procedures that use the global navigation satellite system (GNSS) which enable flights to land at airports despite poor visibility.

Over the last eight months, 21 Indian airports have been equipped with GNSS, aviation officials said.

Installing GNSS is part of a global plan by the International Civil Aviation Organisation (ICAO) to make landings more efficient during adverse weather. India started implementing the plan two years ago, aviation officials said.

The approach procedure, known as Required Navigation Performance (RNP), will help Indian airports without an Instrument Landing System (ILS, a system that allows pilots to land at an airport when there is low visibility) and those where ILS is dysfunctional because of weather conditions like floods.

In Maharashtra, Mumbai, Shirdi, Aurangabad and Kolhapur airports are equipped with this technology. Other Indian airports include Kozhikode, Jabalpur, Indore, Begumpet (Hyderabad), Kolkata, Hubli, Jaipur, Khajuraho, Kannur, Belagavi and Varanasi.

A former Directorate General of Civil Aviation official said, “It is good to see India taking steps to harness GNSS technology for designing these RNP approaches that make runways accessible in a safe and efficient manner. This is the future of aviation, as most of the expensive ground-based technology will be replaced by cost-effective space-based technology.”

RNP procedures are expected to not only reduce delay in arrivals due to poor weather conditions but also increase the accessibility of airports as fewer flights are expected to be diverted.
