 -Manual reconfigurations A few sensor reconfigurations are left at the crew's disposal: ATT/ HDG, AIR DATA and of course, the reconfigurations concerning the EIS DMC (DMC3 globally replacing the DMC1 or 2).
 -Automatic reconfigurations For those systems, of which only the onside sensor/computer is processed by the DMC, the DMC uses the parameters of its onside sensor/computer if operating properly, normal case (N), and it switches as a whole to the offside sensor/computer if the onside one fails, alternate case (A), i.e if the onside bus no longer conveys data or conveys one or several with a failure warning signal. Such is the case for the FACs, FMGC EFIS buses. The DMC switches back to the onside sensor/computer if it works properly again, and under certain conditions.
 For those systems of which the side 1 and 2 sensor/computer buses are processed simultaneously, the DMC can take parameters on either side. In any case, each DMC preferably works with the parameters of:
 -its onside sensor/computer bus.

 Such is the case for the FMGC (FGC) and the RAs buses,
 -the side 1 sensor/computer. Such is the case for the FADEC, FWCs, SDACs, FQIs, FCDCs data buses.
