Accidents and Incidents: Historical aviation accidents and incidents have highlighted the importance of timely and accurate information to flight crews. Many incidents have occurred due to the crew not being aware of critical system malfunctions or operational issues in a timely manner.

Human Factors: Understanding human factors in aviation is crucial. The design of CAS takes into account human cognition, attention, and workload, ensuring that alerts are presented in a way that minimizes confusion and facilitates rapid decision-making.

Technological Advancements: As aircraft systems and avionics technology have evolved, the complexity of managing various systems has increased. CAS requirements have been developed to help flight crews handle these complexities effectively.

Regulatory Authorities: Aviation regulatory authorities such as the Federal Aviation Administration (FAA) in the United States and the European Union Aviation Safety Agency (EASA) play a crucial role in setting safety standards for aircraft. These agencies have issued guidelines and timely requirements for improved and modernized CAS design and functionality.
