If people don't report, then the company doesn't believe there is a fatigue problem and the rosters will get worse
True, and a healthy reporting system is an important element in a safety system. However, there are other elements, and the notion that an absence of data (reports) is an endorsement of an organisations policies and practises is unwise. It is not reasonable for say, management, to assume the system performs well from a safety point of view if there are no adverse, reported events.
It is encumbent on the operator to ensure a safe system and manner of operation, and this comes before data is generated, sifted and interpreted and in hand with oversight from the regulator.
The move towards data led safety systems(such as FRMS) DOES NOT REMOVE the responsibility of an operator to think reasonably and it appears there are those that are using the need for reports and data as a convenient delay before taking effective action to mitigate poor EU FTLs.
The fundamental, intrinsic value of safety data is that it allows you to convince the non aviation types populating airline boards that something presents a risk to the business and needs addressing. The need for sound judgement and decision making at Ops management level has not been replaced.
