Traffic congestion, holding and delays – delays ranging from 20 minutes to 80 minutes at peak traffic period

Extra fuel burn Financial loss to airline, airport operator, service provider.

Cancellation / diversion of flight, schedule disruption Passenger inconvenience ,

Environmental impact - Noise , Emission

Committee to examine and suggest measures for modernisation of MET facilities also Committee interacted with various industry stakeholders, International organisation,,p, ICAO experts, other ANSPs, Boeing, Airbus etc. ICAO Global plan initiatives, ICAO Asia-Pacific Regional guidelines and National regulations were also considered .

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 in phased manner. y Near term : The Near Term Plan is based on application of existing procedures, processes and capabilities. Time frame not more than 2 years.

y Mid Term : The Medium Term Plan is based on emerging procedures, processes and capabilities. Time frame up to year 2012.

y LtLong term : The L ong T erm Pl an is base d on concepts and involves new procedures and requirements based on Research . Features of “ Future Indian Air Navigation System” Master Plan

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 Current status of Master plan implementation : CNS/ATM- Surveillance ‰ 70% o f t he continenta l airspace is covere d un der ra dar surveillance

‰ 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)

‰ ASMGCS – ( SMR + multilateration ) at one airport (Delhi). 5 more system are under implementation at Mumbai, Chennai, Kolkata, Bangalore and Hyderabad.
