“…According to [19], every smart actuator installed in ATD exchanges a total of 224 bits with the flight control computer every time a communication takes place between them. Besides, it has been determined that safety-critical applications related to flight control in civil commercial A/C, demand a hard real-time refresh rate of 1 ms, which was confirmed in [17]. As a consequency every smart actuator dedicated to flight control purposes requires a data transmission rate of 224 kbit/s.…”

This paper discusses the work done until now in the department of safety-critical systems & systems engineering inside the institute of flight systems of the German Aerospace Center (DLR) in the field of data communications over aircraft's power lines.This paper introduces the basic concepts of power line communications by providing a historical and technological background. Besides, it reviews the research done in this subject in the field of aeronautics and presents the models developed as a basis for simulating a point-to-point communication system that uses aircraft's AC power supply grid as the transmission medium. Additionally, a special attention will be paid to the model developed for the transmission channel by reviewing the literature available in the field of power line communications and power delivery.Analyzed literature states that most of the research made on PLC in the field of aeronautics has been made taking into account the DC power supply network and that this research has been supported on empirical tests, not in analytical processes.The work presented here as a part of the research work accomplished in DLR until now has shown that the characteristic parameters of the conductors installed in aircraft must be identified before a detailed and accurate model of the aircraft power supply network can be made.

“…In 2008, J. O'brien et al presented a conceptual architecture for a distributed flight control system with smart actuators and a PLC-based communications backbone [17]. In the presented system, data is transmitted through the 28 Vdc A/C power supply network and is required to have an endto-end latency of less than 1 ms.…”

“…Power line communications (PLC) have been proposed for distributed aircraft control systems in [7]. The PLC communications approach eliminates the need for digital data bus wiring by modulating the data on power cables that are installed between the flight control computer and control surface actuators.…”

This paper reviews the state of the art (SOTA) in distributed flight control technologies using publicly available, scientific and technical publications. Technological developments, such as embedded computing and microelectromechanical systems are enabling advanced aerospace-oriented distributed systems. Distributed systems are comprised of a large number of simple elements, each with its own sensing, actuation and control, in order to obtain the desired behaviour. These systems have the potential to be more economic than a centralized system due to the simplicity of individual components, and possibility of using the same production unit for a different role within the system. The challenge with these systems is the coordination amongst nodes comprising a distributed control network. Benefits of distributed architecture are increased robustness trough redundancy and inherent fault tolerance. The SOTA summary comprises a description of challenges in the design of flight control systems with a distributed structure, technologies currently used in flight control systems and also technologies not specifically related to distributed flight control but applicable for the design of future flight control strategies. Described systems and technologies are represented with examples of real systems including swarms of small Unmanned Aerial Vehicles and distributed networks for Fault Detection and Isolation.I.
