The answers will no doubt vary as there was no standard reference point prior, some were on sub part Q, come caa cap371 etc etc.
I have to say comparing to 371 and on shorthaul I think worse personally, the so called fatigue mitigation that employers have to implement seems to be on very varying levels of what satisfies "mitigated" !
EASA FTL's was allegedly to be a big enhancement for many pilots who were subpart Q before (hence why M'OL was on the record opposing them (as Balpa was), for uk operators I personally feel it was a dilution to cap371 (which wasn't perfect) but hey ho......
I'm yet to see any serious "fatigue mitigation" taking place rather than lip service to it, but what do the CAA care, so long as they get their cheque from the operators !
No limit on discretion once airborne on the last sector is just madness !
