India is among the fastest-growing aviation markets in the world and will be in the top three by 2020. Air traffic continues to grow at a rapid pace - airlines in the country have ordered for 500-odd aircraft in the next decade - and this trend is likely to continue in the future. The magnitude of growth that is expected will create significant pressures on air traffic management in the country to which ad hoc responses will not suffice. Long term solutions will require a new way of thinking with a fresh approach. This seminar, ANS: Challenges & Opportunities, on Air Navigation Services will, for the first time, see professionals from different fields of Air Traffic Management - the Air Traffic Control and Communication, Navigation and Surveillance departments - come together to discuss the challenging issues holistically. The seminar will be particularly important in view of the need to agree and develop solutions that will be globally relevant and in keeping with the ICAO ATM Global Concept document that defines ATM as "the dynamic, integrated management of air traffic and airspace - safely, economically, and efficiently - through the provision of facilities and seamless services in collaboration with all parties".
