Abstract: A flight test installation system for collecting aircraft data includes a sensor level configured to convert aircraft physical inputs into plural measurable electrical parameters, an acquisition level configured to perform at least one of an analogue, discrete or digital bus data acquisition to acquire each of the plural measurable electrical parameters, and a concentration level configured to receive data streams from each of the analogue, discrete and digital data buses, and to switch and duplicate frames in the received data streams without modifying a content of the data streams. The flight test installation system also includes a recording and analysis level configured to record and analyze the content of each of the data streams.

Abstract: The invention relates to a switched flight test installation with an architecture based on four data levels and for which all dated parameters are transported in a single <<packet>> type format: a first level (L1), or sensor level, in which the data are converted from a physical magnitude (pressure, temperature, force . . . ) into an electrical magnitude, a second level (L2), or acquisition level, in which the analogue, discrete or digital bus acquisition is made, a third level (L3), or concentration level, carrying data streams from all second level (L2) systems to fourth level (L4) systems, a fourth level (L4), or recording and analysis level.
