Mention the different levels of integration.
Answer
The different levels of integration include physical integration, functional integration, and data/information integration.
What is the need for systems to be integrated?
Answer
Systems are integrated to reduce overall weight, minimize complexity, improve operational efficiency, and enhance reliability by sharing resources such as power, data, and cooling. Integration also allows for better coordination between subsystems, leading to optimized aircraft performance and reduced maintenance requirements.
