These are the questions which need to be answered: Technologies, use cases and applications: – How much data is already recorded today? o There is information that a B787 generates 500 Gbytes of data in one flight. – Which data are used in which systems, for which purposes and to which Locations in the aircraft (e.g. with sensors etc.)? – How are they transmitted (which physical media, data buses, Communication network architectures, etc.) and where to? o in the aircraft / on-board o on the floor – Where is the data aggregated and processed, with what outputs? – What are the use cases? b. Products and Suppliers: – Which systems (e.g. PM), solutions, architectures and products are available from which providers and which are announced? How does she see Value chain from? – What kind of maintenance procedures are there and how are they used in aircraft today? used? Which statements are made for the future? c. R&D activities: – Which pre-competitive projects in which R&D framework programs (e.g. EU and national research programs) were and are there on the topic? This is the way how it can be approached: The focus is on big data in aircraft. I have to have an overview of all subsystems and the communication between the systems and how much data is being transferred. I have structured it in this way. Airplane is a system of systems – What systems and subsystems are there? (top-down) – Data exchange takes place between the systems as well as within the systems. – For a respective system – What functions (e.g. mechanical systems) are there? – How are these functions monitored, regulated / controlled, …? – What does monitoring mean? (Short-term cycles / real-time up to Long-term cycles such as maintenance) – What does control / regulation (‘Control’) mean? (Short-term cycles / real-time up to Long-term cycles such as maintenance) – How is data recorded for monitoring and controlling the functions? (Sensors, what amounts of data do they produce, where are they located in the aircraft) – Where are the elements of the system in the aircraft (mech. System, sensors, Controller, actuators)? – How many devices are there (network size)? – What are the interfaces to the environment (peripheral systems, pilot, ground) Communication systems and networks (basics) – Principles of a communication system / network (sender, receiver) – communication requirements – Communication standards (topologies / architectures e.g. star, bus, wireless, …) – Background regarding communication standards in aircraft such as CAN, ARINC, AFDX, Fiber, WAIC, …): Performance parameters vis-a-vis communication requirements. Communication networks in the aircraft Communication requirements of the systems such as bandwidth, latency, reliability, Network size, … Communication standards in the aircraft. what are there and what are they used for? Existing communication networks: where will the data be transferred and what will happen there? them? Are they processed in controllers, e.g. for regulation, or stored or forwarded e.g. to actuators, other systems in the aircraft, to the pilot, to Skywise, to the ground …? Big data on the plane plane What is the trend / hype of BD in the airplane? What is the background? What are the developments and prospects. R&D activities Announce in the media Which pre-competitive projects in which R&D Framework programs (e.g. EU and national Research programs) were and are there on the topic? Products and Suppliers Which systems (e.g. PM), solutions, s, architectures and products are available from which providers and which ones are announced? What does the value chain look like?
