Any Professional airline uses the FDM to monitor trends and to inform crews of a potential dangerous situation on one of their flights in order to train, inform and remedy, NOT TO PUNISH.( unless there is intentional endangering of the crew and aircraft by major breaches of SOP and aircraft limitations)
As a result, in any Professional Airline, no crew is afraid of the FDM, which is there to help discover potentially dangerous trends, not to kick you in the a$$.
Any airline that uses FDM to fine. Punish or fire is an airline that should not have an AOC in any developed country.
