The subject matter of this paper is primarily an account of operational experience over a comparatively short period resulting from helicopter activities at the Westland London Heliport. At the outset it is appropriate to recall publication by the Helicopter Association of Great Britain, in January, 1958, of a widely circulated report entitled “Examination of the Case for a London Heliport”. There in was expressed the opinion that there existed an immediate need for an operating base in the inner metropolitan area for use by single-engined helicopters. Further, that it was mistaken policy for the then Ministry of Transport and Civil Aviation to relate the need for a London heliport to the future advent of multi-engined helicopters. In the meantime the initiative had been taken by Westland Aircraft as a private venture to provide a suitable site, and to accept financial responsibility for all procedural and constructional work associated with its development and operation.

Air transport is characterized by a rapid and fairly steady growth in the size, numbers and speed of the vehicles. The systems for navigation and control of this traffic have evolved with the changing problem, and heavy demands have been, and are being, made on electronic technology. At the same time, heavy emphasis is laid on the need for evolutionary changes; old and new systems must be compatible. The present investment, world-wide, in civil air transport is about £100000M. World-wide compatibility is essential between air and ground electronic subsystems, and such systems and operating procedures are, eventually, the subject of international agreements. It follows that any system changes must be heavily influenced by past history, and for that reason it is proposed to discuss airborne secondary radar transponders on a historical basis.

In presenting this paper I shall take but a brief look at a rather interesting subject, the impact of which, on our business in aviation, has doubtlessly touched each and everyone of us. I refer to the subject of Cabotage—an old term which like so many others in human affairs has taken on a new meaning in a world shrunken by our own specialised activity of aviation.Cabotage in its original maritime usage referred to carriage between two places within a geographical unit by earthbound vehicles. The essence of this cabotage however, was its parochial as opposed to international application and this was based on the recognised right of a State to reserve such carriage to its own ships. This restrictive nature of cabotage in maritime law is an exception to the general rule of the freedom of the seas.

CouncilNinth Session: The ICAO Council met in its ninth session in Montreal from January 27 to April 6, 1950 a session devoted primarily to a re-examination of the provisional agenda of the fourth session of the Assembly. The Council decided that the period covered by its annual report to the Assembly should coincide with the calendar year, leaving the period from the first of the year to the opening of the Assembly as the subject of a supplementary report. In considering the work of the fifth session of the Legal Committee, the Council agreed that the draft Convention on Damage Caused by Aircraft to Third Parties on the Surface, a convention which had been prepared by the committee, should be presented to the fourth Assembly which could then consider the desirability of adopting and opening it for signature. Accordingly, the Legal Committee's covering report was distributed to the Contracting States. The Council also decided to recommend to the Assembly that no further consideration be given the question of joint ownership and operation of international services on trunk routes until such times as some group of states, envisaging joint ownership or operation, put forward specific proposals for that purpose.

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.

Objective: The main goal of this study is to clarify the electroencephalogram (EEG) characteristics of the stress response caused by vestibular endurance training under real conditions.Methods: Ten pilot trainees received a series of acute anti-vertigo training stimulations on the rotary ladder while recording electroencephalographic data (64 electrodes). Afterward, the anti-vertigo ability of the subject was tested for the best performance after 1 month of training and verified whether it is related to the EEG signals we collected before.Results: (1) The absolute power of α waves in the C3 and C4 regions is the same as the difference between 1 min before and 2 min after stimulation, and their activity is enhanced by stimulation. Otherwise, the activation of the C3 region after 5 min of stimulation is still significantly changed. (2) Through Spearman's correlation analysis, we found that the α waves in the C3 and C4 the greater the power change, the better the performance of the subject in the proficient stage.Conclusion: C3 and C4 areas are specific brain regions of the stress response of anti-vertigo endurance training, and the absolute power of the α wave can be used as a parameter for identifying the degree of motion sickness (MS). The absolute power changes of α waves in the C3 and C4 areas are positively correlated with their anti-vertigo potential.Significance: Increasing the absolute power of α wave in the C3 and C4 is a manifestation of MS stress adaptability.

NoiseCapture is a smartphone application initially developed as part of a participative approach for environmental noise mapping. After more than 3 years, the database produced from all over the world contributions is considerable (more than 77k contributors, nearly 300k tracks representing about 72 million 1-second measurements, in nearly 200 countries). Beyond the initial objective, other uses of the application have emerged: individually by users for their own needs, by associations of people in charge of the fight against noise pollution, within the framework of educational activities, by researchers for the realization of their own research, by communities to address the subject of noise pollution. As these new applications emerged, the development team of NoiseCapture was led to extend the possibilities of exploitation of these data. Thus, in this paper, we present different possibilities for a user to perform his own data analysis, namely: a local export of data from the smartphone, access to raw data and pre-processed data from the NoiseCapture server, access to formatted GIS layers from OGC standard service. All these methods are enabled thanks to the open source ecosystem, such as Python libraries, R software suite and GIS tools.

The international dimensions of terrorism had been identified prior to World War II. Nonetheless, no agreement could be reached on an acceptable definition, or appropriate action, and the 1937 Convention on the Prevention and Punishment of Terrorism, adopted by the League of Nations, was ratified by a single country. The issue resurfaced in the late 1950s when private individuals perpetrated an alarming number of incidents endangering civil aviation during transnational flights. These incidents led to the adoption of three distinct conventions on the subject, namely the 1963 Tokyo Convention on Offenses and Certain Other Acts Committed on Board Aircraft, the 1970 Hague Convention for the Suppression of Unlawful Seizure of Aircraft, and the 1971 Montreal Convention for the Suppression of Unlawful Acts Against the Safety of Civil Aviation.

Sir William Hildred drew upon his personal experiences until 1966 as Director General of the International Air Transport Association. That body worked closely with the International Civil Aviation Organisation (ICAO)—the author, instigator, and watchdog of Annex 9 of the Chicago Convention which dealt wholly with the subject of facilitation. Neither body had legislative power. ICAO could only make recommendations but these required the assent and action of Sovereign Governments before they became effective. The President of ICAO had said it was the increase in passenger and cargo volume which created the problem but Sir William ascribed a good deal of it to the entrenched conservatism of Governments and their operating agencies.

At the time when the question of the development of civil aviation is so much in the public mind, I am most grateful to the Royal Aeronautical Society for giving me this opportunity of summarising the technical position of the airship to-day.It seems to me that if air transport is to take its place with other existing forms of transport the long distance routes of the world must be established, and my object in summarising the present technical position of the airship is to enable you to form an opinion as to whether the modern airship is capable of taking its place in establishing these routes.I have confined my remarks to the rigid as it is the large airship which is the most suitable for this long distance work.As this long distance work has a distinct bearing, in my opinion, on the value of the airship for naval purposes, I have made a brief reference to this aspect of the subject.
