Flight test data switching system with packet data format

Installing trials switched flight which has an economy based on four levels of data architecture: - a first level (L1), or sensor level, where data conversion of a physical input is performed in a measurable electrical parameter, - a second level (L2), or level acquisition wherein analog, discrete, or digital bus acquisition is made, - a third level (L3), or concentration level, and - a fourth level (L4), or level recording and analysis, characterized in that the third level is a level at which data flows from all systems in the second level (L2) to the systems of the fourth level (L4) meet without the data are modified through this third level, being the only functions the guidance and duplication of frames incidents.
