As the aviation industry moves towards more electric and sustainable aircraft, our PLUS AVIONICS technology positions you at the forefront of this transformation. Deliver lighter, more efficient, and cost-effective onboard systems without compromising on reliability or performance.
With PLC, data is transmitted over the existing aircraft Power Distribution Network. The general concept for PLC in an aircraft is shown on the right side and consists of the following main points:
The PLUS AVIONICS data bus is a PLC protocol and technology platform optimized for realiable and real-time PLC and targeting safety-critical, real-time systems in aerospace applications. It has been designed around:
One of the main design goals has been to use the available bandwidth from the broadband transmission in order to optimize the reliability regarding data availability and integrity rather than simply increasing the data rate.
The PLUS AVIONICS protocol works on top of any power distribution network without requiring any modifications to the existing wiring. The signal is modulated independently of the underlying power signal. PLUS AVIONICS fulfils the main challenges for the use of PLC within the aircraft
PLUS AVIONICS is available as a gateway based on the PLUS Product Platform that implements the PLUS AVIONICS protocol, consisting of
Diehl Aerospace and plc-tec AG have 2018 entered into a cooperation for the further development, certification and industrialization of PLUS AVIONICS, to be integrated into Diehl Aerospace’s systems products. This also enables customers and partners of Diehl Aerospace to utilize the benefits of PLC AVIONICS for their own products and solutions.
Diehl Aerospace together with partner HSLU have won the 2017 Crystal Cabin Award for Cabin Systems for “Power Line Communication (PLC) for Aircraft.”
Diehl Aerospace showcased PLUS AVIONICS as an enabler for the smart cabin of the future at the International Aerospace Exhibition (ILA) Berlin (June 22 to 26, 2022).
Fokker ELMO, a market and technology leader in electrical wiring interconnection systems (EWIS) for aircraft, and plc-tec cooperate since 2018, leading the way in electrification and shaping a cleaner and more sustainable future for aviation.
The Competence Center Intelligent Sensors and Networks is the major research partner of plc-tec, e.g. in cooperations in several EC and LUFO (German aerospace research program) projects.
