I agree with several comments made here.
I think the system is really trying to encourage a Just Culture on the front-line (ie flying) but as has been said, it can all so easily be undone by one decision from a higher rank, possibly even a benign one but one that is not explained correctly or is mis-perceived by the wider audience.
Is the safety system better than it was 20 or 30 years ago? Undoubtedly. Is it being misused by individuals to cover a**e, I don't know. The cynic in me believes possibly, the FSO in me hopes no.
I have seen some very positive benefits at my Stn from the revision of RAF FS, and for me as a pilot, that's what I want.
