This technological project originated from the observation that there has been little evolution in the field of aeronautical wiring over the last 25 years and that the current 'wire by wire' technologies, although reliable, easy to implement and flexible in terms of use, were showing their limits in addressing the critical changes currently in progress.
This resulted in the need for the 'development of a new flat concept', for general electrical harnesses and standard airframe cables and connectors.

- 10% minimum on weight
- 30% minimum on implementation times
- 20% minimum on overall costs
- improvement of advanced design tools
-
improvement of safety:
- guarantee reproducibility and precise knowledge of the position of each signal in the harness
- optimise the electro-magnetic resistance and thermal protection required for each type of signal
- eliminate a large number of individual screening connections
- work no longer performed 'wire-

The proposed approach comprised several independent parts:
- design of a new modular flat harness concept
- study of the distribution of the electrical signals
- definition of the rules, directives and associated IT tools
- design of components ( to be standardised)
- concept validation process.
