What does "aircraft systems integration" involve?

Aircraft systems integration refers to the coordination of various systems within an aircraft to ensure they operate optimally and enhance overall safety. This integration involves the seamless interaction between different systems such as avionics, flight controls, propulsion, and navigation to achieve a cohesive operational environment.

When systems are fully integrated, they can share data and work together, allowing for better situational awareness for the pilots and improved performance of the aircraft. For example, integrating flight management systems with autopilot and navigation aids allows for more efficient and safe flight planning and execution. This level of coordination is essential in modern aircraft, where multiple systems must communicate efficiently to handle complex tasks and enhance safety margins.

The other options describe different aspects not central to the core idea of systems integration. While replacing outdated systems can be part of maintaining an aircraft, it does not encompass the overarching goal of integration. Having systems work independently contradicts the primary purpose of integration, which aims for interoperability. Integrating ground support systems with aircraft, while important, focuses on ground operations rather than the internal systems of the aircraft itself.
