PT6A;
The best source of a company's own FDM event "limits" would be your SOPs. Stay within them and very few if any events are triggered. That was our published standard; when we received calls asking for these limits that's what we said. Also, as stated by others, the limits change with circumstances.
We never published these limits because crews will fly to them and otherwise possibly run their operation with these limits in mind and not other things which may result in an exceedence of less importance when resolving something of more importance...so to speak. That's why flight data analysis requires the participation of active line pilots on the team who know the operation. It is far more complex than most understand.
Some Asian airlines create a blame-and-enforce culture with their FDM Programs, and discipline or even fine their pilots for FOQA exceedences. So the pilots will fly to those limits rather than keeping the overall operation in mind. The experience is a clear example of this kind of pilot response and is to be avoided in a properly-run FDM Program. Otherwise pilots are concentrating narrowly and can make (and have made) decisions based upon approaching FDM limits rather than the overall operation.
