The two major aspects to planning an airport are air-side development and city-side development. While air-side development consists of technical issues related to runways, taxiways and apron, along with air traffic control tower etc, city-side development connects the aeroplane to the terminal building through the aerobridge. A degree in architecture is a big help. One needs to study various rules and regulations including the International Air Transport Association (IATA) norms while designing an airport. An acute business sense coupled with an understanding of the importance of return on investment is also critical. Since India lacks world-class infrastructure facilities, there is a lot of scope for development of existing as well as green airports. The need of the hour is to think globally and act locally.
