Summary: Assistant Based Speech Recognition (ABSR) systems have the potential to reduce air traffic controllers' workload in air traffic control radiotelephony communication. This study investigates how ABSR could support air traffic controllers in a tower environment. The results show that ABSR system, with a command recognition rate of 82.9% and a callsign recognition rate of 94.2%, can reduce workload and improve usability.

Summary: This article introduces knowledge distillation into ASR for Mandarin ATC communications to enhance the generalization performance of the lightweight model. By using the Target-Swap Knowledge Distillation (TSKD) strategy, the potential overconfidence of the teacher model regarding the target class can be mitigated. Experimental results demonstrate that the generated lightweight ASR model achieves a balance between recognition accuracy and transcription latency.

Summary: The study established a framework to measure attentional levels of human operators in real-time animated environments using visual neuro-assisted approach. Results showed differences in visual behavior between attentive and inattentive behavior, and introduced a new Task Engagement Index (TEI) to predict different attentional levels.

Summary: With the increase of digitalization and automation, a new working environment is emerging in air traffic control field, allowing remote control of airports at any given location. The use of directional sound can potentially enhance situational awareness and offload visual perception in air traffic control. Through workshops with air traffic controllers, suitable use cases for sonification in air traffic control were determined and a sonification design named SonAir was developed. Integrating SonAir with an RTC simulator showed potential usefulness in supporting air traffic controllers, although the intrusiveness of SonAir needs further consideration according to the controllers' needs.

Summary: The growing demand for air transportation has led to worldwide air traffic inefficiency due to capacity constraints. The PBN approach, including RNAV and RNP procedures, offers benefits such as reducing route distances, fuel consumption, and perceived aircraft noise, compared to conventional navigation procedures. Case studies in Brazil showed that the benefits of PBN systems vary with aircraft type and individual route characteristics.

Summary: Various optimization models for flight rerouting were proposed to address the rerouting problem caused by uncertain adverse weather and multiple flight-confined areas. Test results demonstrated that, compared to other models, the robust optimization models showed better performance in adapting to scenario changes.

Summary: This paper explores the causal relations among en route inefficiency and identifies multiple sources contributing to it. It proposes strategic route choice and tactical reroute mechanisms. By utilizing efficient trajectory clustering algorithm, tree-based searching algorithm and discrete choice modeling framework, it quantitatively analyzes flight route choice process and establishes linear models to understand reroute process. Through counterfactual analysis, it estimates the contributions of identified causal factors to flight inefficiency. The study reveals strong negative impacts of convection and headwind on route choice process, while other factors like MIT, AFP, and SAA demonstrate varying degrees of negative effects on certain airport pairs.
