Flight data recorder system (FDRS)

*
Data communication management system (DCMS)

*
Flight management computing system (FMCS)

*
Thrust management computing system (TMCS).

The AIMS has software functions that do the calculation for each of these avionics systems.
The AIMS supplies one other software function that many airplane systems use. It is the data conversion gateway function (DCGF).
