Hi,
We used this document to develope our policy.
Flight Data Monitoring Manual
We just follow basic principles in the document and keep FDM as MONITORING. We have no other silly procedures over pilots.
If you look document you will see main policy is share info and develope solution as a team. Pilots will believe FDM results and advantage than they will correct them self.
According us, rest is loosing time. We don't believe punishment, reporting so on.
