Committee to examine and suggest measures for modernisation of MET facilities also

Committee interacted with various industry stakeholders, International organisation, ICAO experts, , g , p ,other ANSPs, Boeing, Airbus etc. ICAO Global plan initiatives, ICAO Asia-Pacific Regional guidelines and National regulations were also guidelines and National regulations were also considered .

The committee drafted a “ Future Indian Air Navigation System ” The committee drafted a Future Indian Air Navigation System (FIANS) Master plan for India.

In accordance with the recommendations of the experts committee AAI as ANS provider has initiated actions incommittee AAI as ANS provider has initiated actions in phased manner.

Current status of Master plan implementation: CNS/ATM-Navigation

GBAS – Ground Based Augmentation System

Under implementation at Delhi and Mumbai Airport

Performance based Navigation

• Performance based Navigation procedures (RNAV-1 SID/STAR ) - -implemented at Mumbai, Delhi and Ahmedabad terminal approach areas w. e.f 28th August 2008 .

• Phased implementation at other terminal approach areas and in enroute areas.

• Reduced separation both in enroute and approach areas – in a progressive manner to enhance capacity

Environmental Benefits Noise abatement Reduced emission • Environmental Benefits – Noise abatement , Reduced emission

Current status of Master plan implementation : CNS/ATM-Surveillance

70% of the continental airspace is covered under radar surveillance

Additional radars under implementation to achieve 100% Additional radars – under implementation to achieve 100% overlapping radar cover over the continental airspace

ADS – C - covers the entire oceanic airspace ( Bay of Bengal, Arabian Sea & Indian Ocean)
