Дана оценка использования цифровой контрольно-измерительной аппаратуры при проверке авиационных систем в соответствии с руководящими документами ARP4754 и DO-178C. Указано, что в автоматизированных стендах на основе ЭВМ, в отличие от традиционных подходов, повышается роль программного обеспечения (ПО). Приведен обзор существующих ре -шений для проверки приемоответчиков управления воздушным движением (УВД). Сделан вывод о необходимости доработки автоматизированного измерительного стенда проверки бортовых систем предупреждения столкновений (БСПС) с целью оценки параметров приемоответчиков УВД на стадиях их разработки и проведения сертификационных работ в соответствии с DO-181E. Сформированы требования к ПО. Представлены результаты практической реализации автоматизированного измерительного стенда. An assessment of the use of digital instrumentation equipment for testing airborne systems under the guidelines ARP 4754 and DO-178C is given. It is shown that in the computer-based automated test bench, unlike traditional approaches, the importance of software increases. An overview of existing solutions for testing air traffic control (ATC) transponders is provided. It is concluded that it is necessary to refine the automated measuring bench for testing the airborne traffic collision avoidance systems (TCAS) to assess the parameters of ATC transponders at the stages of their development and certification under the guideline DO-181E. Software requirements are formed. The results of the practical implementation of an automated measuring stand are presented.

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.

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.
