The requirement organization of the avionics system

Abstract System requirements are the basis of system organization. The requirements for avionics consist of system task requirements, system function requirements, and system equipment requirements. That is, the avionics system requirements are oriented toward the application task organization, establish the application objectives achieved by the system, and build the application requirements of the system; through the system function organization, the systemic function processing procedure is established to build the systemic capability requirements; the system equipment resource organization is established, and the system is established, and systemic hosted applications and functions as well as operational capacity requirements for system processing can be built. Based on the concept of avionics application, function, and resource organization requirements, chapter 3 is divided into three sections. Section 1 introduces the characteristics and composition of systemic application tasks. Section 2 discusses the characteristics and composition of systemic functional capability, including organization of functions in different flight phases. And section 3 discusses the characteristics and composition of systemic resources capability.
