Abstract. Owing to the different approaches for remote tower operation, a standardized set of indicators is needed to evaluate the technical implementations at a task performance level. One of the most influential factors for air traffic control is weather. This article describes the influence of weather metrics on remote tower operations and how to validate them against each other. Weather metrics are essential to the evaluation of different remote controller working positions. Therefore, weather metrics were identified as part of a validation at the Erfurt-Weimar Airport. Air traffic control officers observed weather events at the tower control working position and the remote control working position. The eight participating air traffic control officers answered time-synchronized questionnaires at both workplaces. The questionnaires addressed operationally relevant weather events in the aerodrome. The validation experiment targeted the air traffic control officer’s ability to categorize and judge the same weather event at different workplaces. The results show the potential of standardized indicators for the evaluation of performance and the importance of weather metrics in relation to other evaluation metrics.

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.

Abstract. The paper examines the workload perceived by air traffic control officers (ATCOs) and pilots during continuous descent operations (CDOs), applying closed- and open-path procedures. CDOs reduce fuel consumption and noise emissions. Therefore, they are supported by airports as well as airlines. However, their use often depends on pilots asking for CDOs and controllers giving approval and directions. An adapted NASA Total Load Index (TLX) was used to measure the workload perception of ATCOs and pilots when applying CDOs at selected European airports. The main finding is that ATCOs’ workload increased when giving both closed- and open-path CDOs, which may have a negative impact on their willingness to apply CDOs. The main problem reported by pilots was insufficient distance-to-go information provided by ATCOs. The workload change is important when considering the use of CDOs.
