A LAYERED SUBSYSTEM ARCHITECTURE FOR A FLIGHT MANAGEMENT SYSTEM

摘要

An improved aircraft flight management system (FMS) based on a layered subsystem architecture, residing on a computing platform and including an operator interface subsystem, a communications subsystem, a flight management subsystem, and a database management subsystem, wherein the architecture is predicated on the enforcement of subsystem-dependency rules wherein a given subsystem is allowed to depend only upon another subsystem in the same or lower hierarchical layer.
