ADS - Automatic dependent surveillance on air traffic control

Automatic dependent surveillance on air traffic control: risk assessment based on fluid stochastic Petri nets modeling.
¤ Air traffic (safety)
¤ Petri nets
¤ Risk analysis
¤ Systems simulation

In last decades, the safety critical systems paradigm has changing to adapt itself to new necessities, such as costs reduction and productivity demand growth. In the Air Traffic System, those changes are ruled by CNS/ATM paradigm (Communication, Navigation, Surveillance / Air Traffic Management), based on new digital Technologies, mainly Satellites, applied to Communication, Surveillance, Navigation and Air Traffic Management. CNS/ATM intends to reduce the restrictions of current air traffic paradigm, enabling the growth of air traffic capacity without affecting current safety levels. However, this new paradigm brings together new challenges and needs, mainly related to safety assessment. In face of these new challenges, this work proposed a method of risk assessment constituted by the union of the "absolute" and "relative" assessment methods adopted by the International Civil Aviation Organization (ICAO), by modeling systems using Fluid Stochastic Petri Nets (FSPN) formalism, and by comparison between safety metrics obtained from proposed and legacy system simulations. This method was applied to assess a new concept of air traffic surveillance, named "Automatic Dependent Surveillance - Broadcasting" (ADS-B). As main conclusions, the proposed method was promising to assess system safety properties based on current safety critical system paradigm, especially the CNS/ATM, where FSPN formalism provided important modeling capabilities and discrete event simulation allowed estimating the desired safety metric. Besides, ADS-B has meaningfully reduced the separation losses risks and, therefore, it could be used to air traffic control surveillance system to improve capacity and/or safety levels of air traffic system.
