Inducements Impacts
There are multiple conditions that can cause the the Inducement Strategy to engage. Use the
SPN-FMI reporting in the Active Faults Screen on the operator display to help pinpoint what is
causing the problem. In general, it is best practice to address any problems as soon as a STOP
or WARN illumination is observed, rather than after Inducements kick in – this will help limit down-
time.
