ASTRA: A Scalable Next-Generation ATCO Training Simulator with Autonomous Simpilots
Researchers have developed ASTRA, a new simulator designed to train Air Traffic Control Operators (ATCOs) by automating the role of human simpilots. This system addresses the limitations of existing Western-centric speech models, which perform poorly with Singaporean-accented aviation speech, by fine-tuning Automatic Speech Recognition (ASR) models. ASTRA significantly reduces Word Error Rates (WER) to 23.45% and includes an AI-assisted performance evaluation framework for trainee communications. AI
IMPACT This simulator could improve the efficiency and standardization of air traffic controller training, potentially reducing operational costs and instructor workload.
