T.M. Moles

Hong Kong is situated at the center of the air traffic axis for Asia, and has, at Kai Tak, one of the busiest airports in the world. The areahas experienced a ten-fold increase in population over 25 years and now has the highest urban density in Asia. Hong Kong is in the monsoon belt and is subjected to the very severe weather conditions of typhoons.Kai Tak airport is unique. The main 7,000 foot runway is substantially reclaimed from the harbor which in turn lies within a spectacular mountain bowl. The 310° flight path traverses the north end of the Kowloon peninsula with equally spectacular urban development.Overall disaster contingency planning within this broad spectrum is the responsibility of a joint Police/Military Command. An Aircraft Accident Committee coordinates joint emergency service planning, command and communications training and exercises.Response to an aircraft disaster is initated by Air Traffic Control through the joint Fire Service/Police/Military Command which sets up a discretionary response for intervention, search and rescue by land, sea and air.Although the problems are universal, the Maximum Credible Incident scale is extraordinary to Hong Kong. Unique means of dealing with this problem have been specially evolved here, particularly in the field of fire fighting and marine rescue which involve a Catamaran Rescue and Immediate Care Vessel.

The implementation of Trajectory-Based Operations, invented by the Single European Sky Air Traffic Management Research program SESAR, enables airlines to fly along optimized waypoint-less trajectories and accordingly to significantly increase the sustainability of the air transport system in a business with increasing environmental awareness. However, unsteady weather conditions and uncertain weather forecasts might induce the necessity to re-optimize the trajectory during the flight. By considering a re-optimization of the trajectory during the flight they further support air traffic control towards achieving precise air traffic flow management and, in consequence, an increase in airspace and airport capacity. However, the re-optimization leads to an increase in the operator and controller’s task loads which must be balanced with the benefit of the re-optimization. From this follows that operators need a decision support under which circumstances and how often a trajectory re-optimization should be carried out. Local numerical weather service providers issue hourly weather forecasts for the coming hour. Such weather data sets covering three months were used to re-optimize a daily A320 flight from Seattle to New York every hour and to calculate the effects of this re-optimization on fuel consumption and deviation from the filed path. Therefore, a simulation-based trajectory optimization tool was used. Fuel savings between 0.5% and 7% per flight were achieved despite minor differences in wind speed between two consecutive weather forecasts in the order of 0.5 m s−1. The calculated lateral deviations from the filed path within 1 nautical mile were always very small. Thus, the method could be easily implemented in current flight operations. The developed performance indicators could help operators to evaluate the re-optimization and to initiate its activation as a new flight plan accordingly.

During the past two years the commercial airline operators and the travelling public alike have been forced to acknowledge the rapid increase in airport congestion. This problem is most marked in the North Eastern area of America at the present time but a similar situation will develop fairly soon at major airports in Europe. Even with the introduction of the airbus to scheduled services, the number of aircraft movements at conventional airports, within a given time period, will reach a maximum safe level. The restrictions are imposed partly by the large number of aircraft operations on each runway, and partly by Air Traffic Control safety limits.

The North Atlantic is increasingly developing into the main trade route of the age. Shipping, the pioneer along this highway of commerce, in the past decade has been joined by air traffic displaying a striking growth rate. Not only is the number of aircraft simultaneously plying the Atlantic routes constantly on the increase, but also the volume of passengers and freight transported on each flight. The question, whether such flow of traffic in the air and on water could be dealt with in future with the safety to which it is entitled, has led to world-wide discussions over the past few years concerning the necessity for an air traffic surveillance system for the North Atlantic area. A further question, whether one should not include also sea traffic in such a system suggested itself. The initiative for holding such discussions naturally proceeded less from air and shipping undertakings, but rather from those committees who are entrusted in supervising the safety in the conduct of man and merchandise.

This paper considers the issue of operating aircraft through the North Atlantic's Minimum Navigation Performance Specification (MNPS) airspace. Noting that aircraft constantly strive for reduced fuel burn and uplift, it describes how flight operators and pilots conduct safe, efficient flights through the region. Reference is made to mechanisms of the North Atlantic MNPS airspace in terms of its Organized Track Structure and other routes that exist. These different structures emphasize the level of flexibility available. Flight planning procedures and requirements necessary to obtain oceanic Air Traffic Control (ATC) clearances are mentioned, as is an account of how communication and position reporting procedures operate to apply the Mach Number technique. Other aspects of MNPS operations such as ETOPS operational restrictions, meteorological effects, the employment of Reduced Vertical Separation Minima and planned regional changes aim to provide an overview of the MNPS system's current and future air traffic management.

The appearance of the first marketable root crops with a diameter of more than 50 mm, categorized as elite, in the North-West region of the Russian Federation, may already occur by the end of the third decade of June. The crop price during this period is at least twice the one during mass harvesting. The price depends on the product’s presence on the consumer’s market as well as on weather conditions in the regions of traditional suppliers. In some years, the price can differ by a factor of 3-4. By the time of mass harvesting using traditional technology, the number of elite root crops does not exceed 50%. In order to assess the effectiveness of the proposed early beets cultivation technology, the studies were carried out in the economic conditions of the farm, Leningrad region on the area of 3 hectares. According to the research results, the proposed technology allows to reach 3.3-fold increase of the root crops yield, which are to be sold fresh through the retail network, compared to the traditional one. The gross income using the proposed technology, calculated for sales prices of 2019, amounted to 384.6 thousand rub/ha against 125.2 thousand rub/ha using traditional cultivation techniques.

It is becoming recognised that before civil aircraft can operate at high density, the most important problem to be solved is that of traffic control. Methods exist by which a single aircraft can navigate from a distant point to an airport and let down to a safe landing under bad weather conditions. Difficulties arise when several aircraft are involved at once and long delays can occur in the neighbourhood of airports carrying high density traffic. In this paper an analysis is made of the traffic problem in an attempt to clarify some of the factors involved.

The objective of this study was to examine the potential benefits for air traffic controllers from the use of automated weather advisories. In a part-task simulation, we used a weather support tool called Automatic Identification of Risky Weather Objects in Line of Flight (AIRWOLF) that (a) detects conflicts between aircraft and hazardous weather, (b) alerts the controller, and (c) generates automatic weather advisories. During the simulation, air traffic control (ATC) subject matter experts responded to AIRWOLF alerts and either provided weather advisories to pilots via radio in two main conditions or provided data link communication in a third control condition. Automated advisories (a) eliminate the need for a manual production of weather advisories; (b) reduce the production time, voice duration, and overall advisory duration; and (c) reduce the cognitive workload associated with the dissemination of weather advisories. The results showed that the AIRWOLF tool could support air traffic controller weather avoidance actions and provide accurate and timely weather advisories to pilots. The weather advisory tool could support en route controllers for the safe, efficient, and strategic efforts required to handle adverse weather conditions in the en route environment.

In this paper M. Villiers, Ingénieur en Chef de la navigation aerienne, and M. de Barbeyrac, of the Société d'Etudes des Systèmes d'Automation, discuss the application of a satellite monitoring system to A.T.C. procedures.The paper first discusses control of lateral separation under the headings of present navigation accuracy over the North Atlantic and by a satellite monitoring system. It goes on to discuss control of longitudinal separation with and without monitoring, and finally discusses intervention procedures and aids.The writers conclude that it is possible with a mathematical model to establish a general relationship between the performance of aircraft navigation systems and a monitoring system on the one hand, and the lateral and longitudinal separation of aircraft and the mode of A.T.C. action on the other. From this relationship the number of A.T.C. interventions can be computed and it appears that the reduction of separations resulting from a satellite monitoring system will fit such a system to the forecast air traffic beyond 1975. In addition, the requirement for voice communication, specific to A.T.C., would be extremely limited. The paper was presented to the S.S.T. Working Group, sponsored jointly by the French, German and British Institutes of Navigation.

Abstract: Weather events affect air traffic control (ATC) in many ways, for there are many situations that need to be reported in pilot-controller communication. This paper attempts to analyze the language used to express the impact of meteorological phenomena to air traffic operations, particularly in regard to aeronautical English, that is, the communication used during radiotelephony by air traffic controllers in training situations. For that, two types of analyses will be carried out: one regarding the formulaic structure of lexical units using 11 Aeronautical Meteorology terms within the ATC context (phase 1); and another one concerning the use of these terms by students in three ATC courses (for TWR, ACC and APP facilities) and how it affects their performance during communication activities in a learning environment (phase 2). These analyses will be based on rationales of lexical semantics for terminology; corpus linguistics (CL), comprising English for Specific Purposes (ESP) and learner corpora; and considerations about vocabulary assessment on aeronautical English exams. Results suggest that terminological patterns discussed in this paper show how meaning is dependent on context, and how lexical semantic analysis of terms may contribute to reveal nuances of language used in a specialized context. In this way, it indicates courses have been efficient in teaching and practicing the use of the main meteorological terms related to aeronautical English and that, despite some mistakes students make, evidence points out that they are able to report weather conditions to pilots and to understand pilots’ requests in a proficient level concerning vocabulary.Keywords: meteorology; aeronautical English; terminology; learner corpus; language assessment.Resumo: Eventos meteorológicos afetam o controle de tráfego aéreo (ATC) de diversas formas, dado que muitas situações precisam ser reportadas na comunicação entre piloto e controlador. Este artigo pretende analisar a linguagem utilizada para expressar o impacto de fenômenos meteorológicos para operações ATC, particularmente quanto ao uso de inglês aeronáutico, ou seja, a comunicação utilizada durante a radiotelefonia, por controladores em situações de aprendizagem. Para isso, duas análises foram realizadas: em relação à estrutura formulaica de unidades lexicais contendo 11 termos de Meteorologia Aeronáutica no contexto ATC (fase 1); e quanto ao uso desses termos por alunos de três cursos ATC (para os órgãos operacionais TWR, ACC e APP) e como isso afeta seu desempenho durante as atividades de comunicação em um ambiente de aprendizagem (fase 2). Essas análises serão fundamentadas nas teorias de semântica lexical para terminologia; linguística de corpus (LC), compreendendo Inglês para Fins Específicos (ESP) e corpora de aprendizes; e considerações sobre avaliação de vocabulário em exames de proficiência de inglês aeronáutico. Os resultados sugerem que os padrões terminológicos discutidos mostram como os significados dependem do contexto, e como a análise léxico-semântica de termos pode contribuir para revelar nuances da linguagem utilizada em contexto especializado. Desta forma, demonstrou-se que os cursos foram eficientes no ensino e na prática do uso dos principais termos meteorológicos e que, apesar de alguns erros cometidos, as evidências apontam que os estudantes foram capazes de reportar condições meteorológicas e compreender as solicitações dos pilotos com nível de proficiência adequado em relação a vocabulário.Palavras-chave: meteorologia; inglês aeronáutico; terminologia; corpus de aprendizes; avaliação de línguas.

In the article the analysis of functioning a joint decision-making (A-CDM) system of Sheremetyevo Airport is presented during airport operation in a "rush hour". Domestic and international programs of air traffic management (ATM) development assume that the airports will be completely included into the air traffic management network as components of this network. Cooperative decision-making will be used to provide a "seamless" process of planning. This process will take place with participation of airspace users, suppliers of an air navigation service and airports (with use of the automated facilities of arrival, departure and traffic on airfield surface) for the benefit of sequence management to increase runway capacity. The runway equipment has to be modernized, separation standards among aircraft on arrival and departure should be reduced, modern navigation and traffic control on an airfield surface aids have to operate. The runway is referred to the resources which operate according to the principle of only one client service. Influence of weather conditions (the wet runway, severe wind, low visibility) determines the airfield capacity. Arrival and departure control allows optimizing aerodrome operation from the view of cost efficiency and ecology. The system of joint decision-making for an airport is a complex of the procedures aimed at increasing level of air traffic flows organization, airfield and airspace capacity through raising a level of event predictability and optimization of the resource use process. The system allows operating information to obtain the modified output data for decision-making. The main system objectives are to increase the level of temporary accuracy of an event emergence and also its predictability.
