- Safety is of primary importance in aviation industry. The designers of the aircraft systems must ensure that the system must provide intended function with required levels of safety to different stakeholders such as passengers, flight crew and maintenance personnel. The system design process needs to deal with the increasing complexity and size of systems, motivating the replacement of time consuming manual techniques with automated and semi-automated approaches. System safety analysis techniques are well established and are used extensively during the design of safety-critical systems. Despite this, most of the techniques are highly subjective and dependent on the system knowledge and skill of the practitioner. In the recent times, Model-Based Safety Assessment (MBSA), have been increasingly used to model systems to analyze the faults. Model-Based Safety Analysis (MBSA) is an approach in which the design and safety engineers share a common system model created using a model-based development process. MBSA intends to act as a bridge between design engineers and safety engineers reducing the time required to verify the safety of a new designed system. This paper presents a case study to describe the system safety analysis performed for Actuator Control System (ACS) using Model-Based Safety Analysis, an approach in which the system and safety engineers collaborate with a common system model created using a formal model-based development process.
