Safety Aspects for The Design of Automatic Conflict Resolution in TCAS
Maurício Spiazzi Richter, José Alexandre Tavares Guerreiro Fregnani, Donizeti de Andrade

Última alteração: 2023-09-26


There is an increasing level of automation present in every new generation of aircraft cockpits. This paper focuses the analysis on the automation of conflict resolution in traffic alert and collision avoidance systems (TCAS), bringing a discussion about the human factors related to the interaction of pilots with such systems, as well as the role-sharing between them. Grounding the discussion on relevant prior research on that topic and presenting the existing risks involving mid-air collision and in-flight loss of control, impacts in aviation safety are also evaluated, including the potential positive and negative outcomes of this extra assistance. With that, this work draws attention to the most important concerns when designing this kind of systems, in order to enhance the benefits and mitigate the side-effects aiming a development that correctly takes into account the human behavior when dealing with automated systems.

Keywords: Automatic RA; TCAS; Aircraft automation; Human factors; Aviation safety.
