Stockholm TMA capacity - A study of the landing rate and its effects on arrival outcome

Rydin, Axel January 2013 (has links)
Stockholm TMA handles traffic to Sweden’s two biggest airports movement wise: Stockholm Arlanda and Stockholm Bromma. The airports are located in close proximity to each other, meaning traffic in and out of the airports is likely to conflict, depending on the runway configurations. Stockholm TMA capacity will depend on how complex the traffic is, especially in the arrival sector (sector East), as well as weather, wind and other capacity factors. The thesis focuses on arriving traffic to Stockholm Arlanda. The number of arrivals for any given hour is restricted by a landing rate. The landing rate is set depending on a number of factors. For a high landing rate to be set, Stockholm Arlanda will need to be in traffic peak, utilizing one of the runway configurations used for hours of high traffic intensity. Why was a certain landing rate set? What were the main contributors? What was the outcome of the rate in terms of arrivals?

Metodologia de análise de impacto em segurança crítica da automação das tarefas do controlador de tráfego aéreo da torre de controle de aeródromo. / Impact analysis methodology for safety of aerodrome control tower air traffic controllers tasks automation.

Dirickson, Yuri Maximilian Rottner 16 May 2016 (has links)
Com o crescimento contínuo na utilização da aviação como meio de transporte de pessoas e carga, o sistema de gerenciamento de tráfego aéreo (ATM) está no limite de sua capacidade. Para lidar com esse problema, a Organização de Aviação Civil Internacional (OACI), junto com diversos países membros, desenvolveu um novo conceito de ATM chamado CNS/ATM, composto de uma série de melhorias tecnológicas para melhorar a capacidade e desempenho do sistema, onde muitas dessas melhorias são automatizações de tarefas de operadores humanos, pilotos e controladores de tráfego aéreo (ATCo). Com o tempo percebeu-se que apenas avanços tecnológicos não seriam o suficiente, que era necessário uma integração maior entre todos os sistemas ATM, que garantisse uma interoperabilidade entre os sistemas. Portanto, o conceito CNS/ATM evoluiu para o conceito ATM Global, onde o planejamento de modernização se dará de forma integrada e global, incluindo muitas das melhorias previstas no conceito CNS/ATM. Essa mudança de paradigma faz surgir diversas questões de como essas mudanças impactarão no atual sistema, do ponto de vista econômico, ambiental, desempenho e segurança. Para entender os perigos envolvidos na execução dessas novas tarefas, utilizam-se diversas técnicas e modelos clássicas como a Análise de Árvores de Falhas (FTA) ou a Análise de Árvore de Erros (ETA). Essas técnicas tradicionais consideram que acidentes são causados por uma sequência de eventos de falha, todos com uma relação de causa e efeito. Essa suposição não é considerada mais suficiente para entender como acidentes acontecem nos sistemas mais atuais, onde cada vez mais eles se tornam mais complexos e mais dependentes da interação com softwares. Para lidar com essa dificuldade foram criados alguns modelos para entender acidentes utilizando a teoria de sistemas, como exemplo o Systems-Theoretic Accident Model and Proccesses (STAMP). Diversos estudo mostram que esses modelos ou métodos são capazes de representar problemas na estrutura de controle que as técnicas mais tradicionais não conseguem, inclusive incluindo fatores organizacionais na sua representação. Considerando todos esses fatos, este trabalho de investigação científica propõe uma metodologia de análise de impacto em segurança crítica da automação das tarefas dos ATCo de uma torre de comando de aeródromo (TWR). A metodologia consiste na modelagem dos perigos e acidentes envolvidas nas tarefas do ATCo da TWR utilizando o modelo sistêmico STAMP) depois na análise subsequente dos cenários antes da automação e depois da automação utilizando a técnica Systems-Theoretic Proccess Analysis (STPA), criada a partir do STAMP, para levantar os fatores causais de perigos e seus requisitos de segurança em cada cenário, de forma a ser possível obter uma comparação do que foi modificado com a automação proposta das tarefas. Para validar a metodologia, foi analisada uma tarefa do ATCo da TWR como exemplo. Espera-se obter com a metodologia proposta uma forma mais objetiva e sistêmica de obter o possível impacto em termos de segurança crítica da automação de uma tarefa específica, sendo possível então determinar qual a melhor forma de se pensar essa automação no contexto do ATCo, podendo assim contribuir para a modernização segura do sistema ATM. / With the increasing growth of aviation as mode of transportation for people and cargo, the Air Traffic Management (ATM) system is on its limits. In order to cope with that, the International Civil Aviation Organization (ICAO), together with country members, developed a new ATM concept called CNS/ATM, bearing several technological improvements with the objective of enhancing capacity and performance of the system, where many of these improvements are automated tasks of human operators, pilots and air traffic controllers (ATCo). In time, it was seen that technological improvements were not enough it was necessary a greater integration between all ATM systems, which would guarantee an interoperability between them. Therefore, the CNS/ATM concept evolved to a Global ATM concept, in which the modernization plan would occur globally and integrated, including many of the improvements of the CNS/ATM concept. This paradigm shift raised several questions on how these changes would affect in the actual system from an economic, environmental, performance and safety points of view. To understand the hazards of the new tasks, several traditional techniques and models are used, like Fault Tree Analysis (FTA) and Error Tree Analysis (ETA). These traditional techniques see accidents because of a chain of failure events, all with an effect-cause relation. This assumption is no longer considered enough in order to understand how accidents occur in actual systems, which became more complexes and more software dependents. To cope with this difficulty, other models were created to understand accidents using systems theory, for example the Systems-Theoretic Accident Model and Processes (STAMP). Several studies show that these models or methods are capable of finding more problems in control structure that the traditional techniques, including organizational factors. Considering all the facts, this scientific investigation propose a methodology for analysis of the impact on safety for the automation of ATCo from Control Tower (TWR) tasks. This methodology consists in modeling the accidents and hazards of the TWR ATCo tasks using STAMP. Then the Systems-Theoretic Process Analysis (STPA) technique, created for STAMP, is used to gather all causal factors for hazards and its safety requirements in each scenario, in order to compare what changed with the automation of tasks. The objective of proposed methodology is to obtain a systemic and objective way of finding the possible impact on safety from the automation of a specific task, enabling the possibility of determining the best way of designing the automation in the context of ATCo, contributing to the safe modernization of ATM system.

O PIP/ATC, política estratégica do Governo de Minas, tem a aspiração de que toda criança leia e escreva até os oito anos de idade. Suas ações se estruturam a partir dos resultados do Proalfa, avaliação sistêmica, aplicada anualmente aos alunos concluintes do Ciclo da Alfabetização. A regional analisada vem paulatinamente apresentando resultados inferiores à média estadual, a despeito de caraterísticas peculiares que lhe favorecem quanto à implementação do PIP. Nesse sentido, este trabalho se propôs a investigar possíveis relações entre o desempenho da SRE e o modo como o programa é implementado nas escolas, o que remete ao papel da Equipe Regional (ER). A pesquisa, de base qualitativa, se desenvolveu como um estudo de caso, combinando instrumentos metodológicos tais como a análise documental, a aplicação de questionário e a realização de entrevistas com atores na cadeia de implementação do PIP, na SRE e nas escolas. Ao avaliar a implementação, comparando o desenho do programa com as ações efetivamente executadas, as contingências mostraram-se especialmente ligadas a uma baixa sistematização da rotina de trabalho da ER. A análise dos dados mostra a implicância da gestão neste contexto, uma vez que o baixo controle institucional abre espaço para o exercício discricionário dos implementadores, o que, sem o devido controle, tende a afastar-se das estratégias inicialmente desenhadas. Neste sentido, o Plano de Ação Educacional (PAE) aqui proposto volta-se para a atuação da Equipe Gestora da SRE, com vistas a fortalecer a atuação da equipe de campo em atendimento às escolas. Propondo a reorganização de algumas rotinas de trabalho e a criação de novas estratégias, o PAE sistematiza ideias, sugestões e modelos, visando maior eficácia na implementação do PIP. / This study aimed to evaluate the implementation of the Pedagogic Intervention Programme / Literacy in Right Time (PIP / ATC) in an Education Regional Superintendent, here called SRE "Zona da Mata". The PIP / ATC, strategic policy of the State Government, has the aspiration that all children read and write until eight years old. Its activities are structured from the Proalfa results, systemic evaluation, applied annually to the graduating students of the Literacy Cycle. The analyzed regional is gradually presenting low results compared the state average, in spite of peculiar characteristics that favor him in PIP implementation. In this sense, this work proposed to investigate possible relationships between the SRE performance and how the program is implemented in schools, which report the function of Regional Team (ER). The research, qualitative basis, developed as a case study, combining methodological tools such as document analysis, the use of questionnaire and interviews with actors in the PIP implementation in the SRE and schools. In order to evaluate the implementation, comparing the program design with the actions actually executed, contingencies proved particularly related to low systematization of the ER work routine. Data analysis shows the management implication in this context, since the low institutional control makes room for the discretionary exercise of implementers, which without proper control, tends to move away from strategies originally designed. In this sense, the Education Action Plan (PAE) proposed here turns to the SRE Management Team performance, in order to strengthen the field staff operation in schools attendance. Proposing reorganizing some work routines and creating new strategies, PAE systematizes ideas, suggestions and models, seeking greater efficiency in PIP implementation.

Trendy ve spotřebě léčiv z ATC skupiny A10AA (inhibitory HMG-CoA reduktázy) za období 2005-2015 v České republice / Trends in the Consumption of a chosen ATC Group A10AA (inhibitors HMG-CoA reductase) in the period 2005-2015 in the Czech Republic

Freimann, Antonín January 2016 (has links)
The thesis deals with trends of drug consumption for the ATC group C10A (HMG-CoA reductase) in the Czech Republic in the years 2005 - 2015. The goal of this work is to analyse the consumption of statins (cholesterol lowering drugs), as well as to analyse the consumption trends (expressed in terms of prescribed daily doses) and subsequently explain the causes of the detected trends. The main method used in this work is the analysis and interpretation of data provided by the State Institute for Drug Control (SUKL). Individual consumption data sets are compared to each other and global trends are inferred based on the obtained results. In the practical part I analyse the consumption for the individual ATC groups according to their increasing lipid-lowering efficacy, according to the pharmaceutical companies involved and according to the experts' recommendations (within the framework of cardiovascular disease treatment). The conclusion of my work shows that the overall drug consumption for the the studied ATC group (given by the DDD/package total) was steadily increasing during the studied period while the consumption expressed in financial units was decreasing (ie. the financial burden on the health system was reduced). The total number of sold packages shows a slight decrease due to the sale of bigger packages with more powerful statins during the studied period.

Progress in Global Air Traffic Management (GATM) Avionics System Test at the Air Force Flight Test Center

Switzer, Earl R., Fleishans, Amy D. 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper presents a progress report on Global Air Traffic Management (GATM) avionic system test activities at the Air Force Flight Test Center. In many parts of the world today the continuing growth of commercial air traffic is running up against limits brought on by overuse of aviation resources. Air corridors in Europe and on transoceanic air routes are operating at maximum capacity. Civil Aviation Authorities (CAAs) are working these challenges on two levels—near-term incremental improvements and long-term visionary changes. Each country has a CAA; ours being the Federal Aviation Administration (FAA). Near-term solutions focus on better utilization of resources such as air space and frequency spectrum and improved performance of air traffic control facilities. Long-term visionary changes, such as free flight, could fundamentally change the current civil aviation business process model. CAA policies and standards are driving near-term improvements and migration toward long-term objectives. This initiative is referred as Communication Navigation Surveillance/Air Traffic Management (CNS/ATM). Implementation of the U.S. military’s vision, Global Reach/Global Power, requires the ability to rapidly deploy armed forces to major regional conflicts anywhere in the world, and to sustain these forces for as long as it takes to resolve these conflicts. To achieve this goal and accomplish rapid deployments while at the same time minimizing costs, the Air Force has adopted a solution that makes extensive use of CNS/ATM. The Air Force calls its initiative Global Air Traffic Management (GATM). Air Force aircraft equipped with GATM avionics will be able to use CNS/ATM capabilities such as reduced vertical separation minimum (RVSM), 8.33 kHz data links, automatic dependent surveillance - broadcast (ADS-B), and global communication networks. These capabilities make possible improved flight safety, lower fuel costs, and quicker turn times. The Air Force Flight Test Center supports the GATM initiative by providing Air Traffic Control (ATC) Communications Test Facilities and Avionic System Test (ACTFAST) capabilities to support aircraft modification programs.

Får tågförare tillräcklig trafikinformation via ATC-systemet? : En explorativ intervjustudie och utvärdering av dagens tågförarsystem på Kustpilen, Linköping-Kalmar / Do the train drivers get enough trafic information from the ATC-system?

Johansson, Regina January 2010 (has links)
<p>ATC (Automatic Train Control; automatisk tågkontroll) är ett säkerhetssystem som automatiskt bromsar ner ett tåg om föraren skulle missa en hastighetsnedsättning eller en stoppsignal. Systemet ger även föraren information om när det är dags att exempelvis sänka hastigheten. Detta genom tonstötar och blinkande siffror på ATC-panelen. Många förare anser dock att det saknas väsentlig information i gränssnittet till ATC-panelen, visar rapporter från Banverket (Kecklund, 2001). Eftersom information som skulle hjälpa föraren att planera körningen framåt i tiden saknas, och föraren därmed ofta väntar på indikationer från systemet, ”kör på pipet”, kan olyckor ske där ATC-övervakningen saknas eller gått ur funktion. Det kan bero på att förare som är vana att ”köra på pipet”, vid situationer där ATC saknas, ingriper för sent eller inte alls eftersom de väntar på indikationer från ATC-systemet. Studier visar även att uppgifter som inte kräver särskilt mycket av människans kognitiva resurser kan ge en ”mental underbelastning” vilket i sin tur kan leda till för låg uppmärksamhetskapacitet och sämre prestation.</p><p>Denna studie undersöker hur förarna anser att ATC-systemet fungerar idag, samt hur det bör utvecklas och förbättras. Syftet med studien har varit att belysa tågförarnas åsikter om ATC-systemet. Att ta reda på vilken information de får genom systemet idag och vilken information de skulle önska. <em>Hur </em>informationen ska presenteras har också varit en viktig fråga. Ett syfte har också varit att undersöka hur förares olika körstilar och attityder gällande ansvarsfördelning mellan förare och system samvarierar med deras åsikter om systemet.</p><p>Resultaten av studien ger möjlighet till att eventuellt kunna utveckla ATC-systemet för att bättre passa förarens sätt att arbeta. En sådan utveckling skulle även kunna ge föraren ett mindre automatiserat arbete vilket kan minska risken för försämrad prestation till följd av låg uppmärksamhetskapacitet.</p><p>I studien genomfördes två inledande observationer för att få en inblick i förarens arbete och informationsmiljö. Efter detta delades frågeformulär ut till alla förare, inom det företag som kontaktats, för att fånga upp olika körstilar och attityder gällande ansvarsfördelning. Ostrukturerade intervjuer hölls med sex förare. Formulären och intervjudokumentationerna analyserades sedan för att göra det möjligt att besvara frågeställningarna.</p><p>Studien har visat att förarna tycker att informationen de får från ATC-systemet är knapphändig och att de skulle önska tillgång till information som gör det möjligt att planera körningen framåt i tiden, så som exempelvis information om flera hastighetsbesked och signalbilder på rad och avståndet fram till dessa, samt information om var andra tåg befinner sig och avstånd till dessa. Studien har även visat att alla förare har ett externt LOC (Locus of control) och att alla har en körstil där man kör på pipet och inväntar indikeringar från ATC-systemet innan man agerar, vilket skulle kunna innebära att de reagerar sämre vid avsaknad av ATC-övervakning.</p>

En systemanalys av flygtrafikledningstjänst med hjälp av FRAM

Sonnerfjord, Daniel January 2011 (has links)
Metoder och modeller är viktiga redskap för att utreda såväl potentiella risker som uppkomna olyckor i sociotekniska system. Vilken modell som används avgör vad en analys tittar på och också vilka åtgärder som vidtas. Därför är arbetet med att utveckla både användbara och riktiga modeller viktigt. Denna uppsats har med ett systemperspektiv tillämpat FRAM på en avgränsad del av ett flygtrafikledningssystem med avsikten att skapa förståelse för ett systems funktionalitet och kontextberoende variabilitet. För att illustrera variabiliteten beskrivs ett par scenarion med koppling till insamlad data. Modelleringen har skapats utifrån en triangulering av insamlad data och i resultat och diskussion lyfts framförallt tillämpningen av själva modellen upp för diskussion. Slutsatsen av studien är att modellen kan adressera risker genom att illustrera den dynamiska interaktionen i ett sociotekniskt system samt att modellen utgör ett stöd för att identifiera åtgärder i flygledningssystemet. Slutsatsen är också att modellen som är relativt ung behöver utvecklas på vissa områden för att tydliggöra hur funktioner för dynamiska och informationsbearbetande system generellt kan konstrueras på bästa sätt för att återge tillstånd och processer. Kritik riktas mot att modellen i nuläget är svåranvänd och kräver stor förkunskap vilket kan verka negativt på modellens användning. Slutligen har studien bidragit med förslag på åtgärder för att stödja FRAM som metod.
