ICAO Annex 6 mandates that all airlines are required under regional legislation to implement Flight Data Monitoring (FDM) programs. These are supposed to identify trends, such as frequent unstabilised approaches at a particular airport or other exceedances, which are passed onto the relevant department for appropriate action, such a restriction, change of SOP or more emphasis on a particular area during simulator training.
The data is anonymous, unless something flags up as warranting tea and biscuits. In this case the guilty party receives an invitation to the office for a frank exchange of views on company procedures with a management pilot. This exchange is mostly one way and the management pilots view is normally the accepted one, unless the other pilot has an alternative means of paying his bills.
The data is only useful if it is interpreted properly and corrective action taken.
