    Review of Current State of Artificial Intelligence/Machine Learning and Other Advanced Techniques Related to Air-to-Air Collision Risk Models (CRM) in the Terminal Airspace
    Sherry, Lance ;
    Shortle, John
    2023-05-01 | PDF
    Collision Risk Models (CRM) are used by regulatory safety agencies to determine the safe separation minima and monitor the air-to-air collision risk level of an airspace. CRMs estimate the expected number of aircraft collisions and "total" risk for a given air traffic concept-of-operation (e.g., parallel approaches). The fidelity of the models, and ...

    Andersson, Bjorn ;
    de Niz, Dionisio
    2023-04-01 | PDF
    Many parts in aircraft today rely on software that interacts with its physical environment. Typically, this interaction involves taking sensor readings, sending actuation commands, reading commands from humans, and presenting information to humans. These interactions require that the software deliver results at the right time,as argued in the guid ...
