In some cases, you may want to define the parameters of a failure mode using an expression that refers to the current value of the FMCV. When specifying failure mode parameters, the current "age" of the selected failure mode is available as a locally available property called FMCV (referenced as "~FMCV").
Note, however, that the FMCV local variable is only available for failure mode parameters that are "dynamic" (i.e., where changes take effect immediately).
