that FDM is what I remember reading here as HOMP, isn't it?
A google search shows:
With the introduction of HUM systems, the number of incidents relating to technical malfunctions decreased and as a consequence the proportion of incidents relating to aircrew error increased. Interest therefore turned to implementing an operations-based monitoring programme, like the fixed wing FDM, but tailored for helicopter operations. As a result, the concept of a helicopter Operations Monitoring Programme, HOMP, was developed and trials, sponsored by the UK CAA and Shell Aircraft, started on the North Sea in 2001.
and this interesting document for people like me that know nothing about it:
