Technique for implementing a functionality tree for an air traffic management system

摘要

Managing requirements to incorporate technology advances and user requested enhancements to fielded Air Traffic Control (ATC) systems is challenging. Due to the complex interrelationship between the various subsystems of an ATC system, adding new or revising existing operational requirements is complicated. Operational requirements must be translated into system requirements and integrated into all appropriate existing subsystems. A functionality tree (FT) also helps reduce implementation and integration time and costs by catching potential inconsistencies during requirements definition rather than during implementation and testing.
