DISTRIBUTED CONNECTED AIRCRAFT COCKPIT FLIGHT MANAGEMENT SYSTEM AS A NETWORK NODE WITH API SERVICE CAPABILITIES

摘要

An avionics system in an aircraft for providing flight data from an onboard flight management computer (FMC) to requesting applications is disclosed. The system includes a flight management system (FMS) service layer executing on the FMC on a thread separate from a thread that executes FMS core functions. The FMS service layer provides a FMC networked node server for responding to queries from a plurality of external applications for data generated from the FMS core functions without interrupting the FMS core functions. The FMC networked node server is configured to: receive a request from a client application using a server specified API for data elements from a specified input flight plan; retrieve the specified input flight plan from the FMS core functions; extract the requested data elements; and output the requested data elements to the client application without affecting the active thread that executes FMS core functions.
