With the advent of increasing numbers of high-speed, high-altitude aircraft on the airways of the world, airlines, aircraft manufacturers, government agencies responsible for navigational standards and air traffic control, as well as military agencies are actively engaged in studies and action directed towards significant changes in longrange air navigation practices and procedures.These changes have been dictated by the need to utilize to best advantage the ‘limited’ air space available on long-range air routes to each individual aircraft, because of the fantastic growth rate in numbers of aircraft operating the trunk routes of the world.In order to limit the amount of airspace required around each individual aircraft separation standards are enforced by the various agencies responsible for control of air traffic along these major trunk air routes. These separation standards are based on longitudinal, lateral and vertical limits between adjacent aircraft. In order to ensure that operating companies and flight crews are aware of these requirements, appropriate legislation is introduced by either international or national agencies and promulgated in readily assimilable form in regulations, orders, or flight or operation manuals.

The application of automatic data processing techniques to air traffic control has been espoused by both operational and research and development groups dealing in air traffic control throughout the world. As far back as 1947, in the U.S.A., the Special Study Group, SC-31 of the Radio Technical Commission for Aeronautics suggested that a high degree of automation be applied—including rigid control of all flights and their times of arrival.

The purpose of this contribution is to draw attention to some of the major areas in A.T.C. where there are difficulties and to outline the steps that are being taken to surmount them.Before looking quickly at some of the technical problems I think it might be worth taking a brief look at two important aspects which surmount the whole scene: namely the Civil/Military situation and the birth of Eurocontrol.The relationship between service and civil authorities on A.T.C. matters springs directly from the differing requirements of the two sides for air space. The increasing use of jets by civil operators has made this problem more acute because now the Service aircraft not only have to be shepherded up through the commercial traffic, but also protected from them in the upper levels. The requirements of research aircraft are also stringent and yet again, different.

Since the advent of large-scale commercial aviation in the mid 1940s, a system of routes has been developed between airports serving the major conurbations of the world. To prevent collision between aircraft using these routes and off-route traffic, protection is provided to the routes and to the vicinity of airports by means of controlled airspace, airways (AWYS), control areas (CTAS) and control zones (CTRS). Zones commence at ground level and the base an area is at a defined altitude. Inside this controlled airspace certain rules apply which are more stringent than those applied outside, and all movements are subject to Air Traffic Control (ATC).

With increasing air traffic flow, air traffic control system of Chinese to ensure aviation safety is facing new challenges. Without air space enlargement, air traffic is more and more crowded, to prevent aircraft collided with the aircraft, to prevent the aircraft and ground obstructions, ensuring air traffic is an important issue China civil aviation, and it is also the main task of ATC system. In this paper, based on the research and design of the airport PBN flight procedures, according to the operation of the program, the problem of poor runway CDA, approach procedure was optimized using the fusion point program approach, the ATSAB direction, improve the operation effect of CDA.

Air travel at 600 m.p.h. to 650 m.p.h. in the next decade and the use of multi-seat twin rotor helicopters on internal air routes to help to solve terminal delay problems, bring in their train growing problems of Air Traffic Control. Full use of high speed civil transports and helicopters does not seem practicable within the British Isles unless the problem of the siting of landing strips is reviewed and unless ideas on this subject are recast in the light of growing experience.To the commercial airline pilot Great Britain is indeed a “tight little island.” It will appear smaller yet when the de Havilland Comet jet air liner operates to time-tables of approximately double the speed of most of the existing schedules of today.

In a procedural Air Traffic Control environment, navigation standards are related to separation standards because of the way they both affect the collision risk. The Air Traffic Studies division of the Mathematics Department at R.A.E. has developed methods of estimating the collision risk procedural systems and these provide rational grounds for decisions on separation standards. In a radar-monitored system navigation accuracy and separation standards both affect the workload of the controller on the ground and it is necessary to study these effects to ensure that he is not overloaded. In addition the problems of estimating the collision risk will become more complicated. I shall very briefly describe the mathematical theory of collision risk for parallel tracks. A fuller description has been published in the Journal.

There is vigorous growth of air traffic in India in the last decade. The passenger air traffic has increased by more than 10 per cent annually during this time. As per the report of Airbus Global Market Forecast (2016-35), domestic air traffic in India is supposed to increase by fivefold in coming decade. The air traffic movement is also increasing at rapid rate globally which is increasing at the rate of 5.7 % per annum in the last decade whereas the World GDP growth in the corresponding period was only 2.6%. The passenger transport in the last decade has increased by 1.47 billion at the global level. As per the report of International Civil Aviation Organization (ICAO), India has experienced a double digit growth rate of 15.7 per cent in passenger traffic and 9.0 per cent growth rate in freight traffic which is much higher than GDP growth rate of India. The heavy air traffic in India is evident from the India’s revenue passenger km which is 13th in the World with 140.4 billion. This entails creation of air traffic infrastructure for smooth movement of traffic in India. The constructions of modern airports and expansion of existing airports are important addition to air traffic infrastructure. The concept of airport cities or aero city imply development of innovative business ideas within the designated area whose cost-benefits if taken into considerations are more than the cost-benefits of its counterpart in the central business district. Major airports in India such as Delhi, Mumbai, Kolkata and Chennai, Hyderabad and Ahmedabad etc. are growth and employment drivers of Indian economy in aviation sector. There are direct, indirect and induced effects on income and output. However, the calculations are complex as it is related with backward calculation of and calculation of input-output analysis. Further all the airports do not generate the same output and employment. In some airport employment increases but output do not increase simultaneously. As a global practice, the increase in airport infrastructure requires a study of its feasibility in a cost-benefit format. This is carried out in terms of financial and economic viability study. In this study, we have carried out an economic and financial analysis of three major airports in India such as Chennai, Kolkata and Ahmedabad airports for twenty years’ time period. In the cost stream, we have considered capital expenditure and on the benefits side the increase in income, employment, outputs in terms of direct, indirect, induced and catalytic terms. An attempt has been made to measures all these benefits against the cost streams through an economic and financial analysis. The feasibility of investments in airport infrastructure has been calculated in a cost-benefit format to find out the internal rate of return. The robustness of the investment has been tested by carrying out a sensitivity analysis at an increasing cost and decreasing benefits conditions and vice-versa. The calculated IRR both economic and financial are well above the 12 per cent as per the guidelines of Asian Development Bank.
