SA - don't know.
Some points:
FDP - under EUOPS, you have probably a 10:30 FDP (it's a bit 'woolly' on when the FDP ends.) That is a 'cushy' FDP (12hrs under EUOPS by any means). Heaven knows what the new rules will produce!
DUTY affects only rest before next duty.
Turn-round time is not really material since you remain on FDP.. It does of course potentially allow them to 'squeeze' in another sector BUT this lowers from 13 hours your available FDP. If turnround time is NOT enough for the operation, delay the flight. A few days of this will cause a re-think at HQ PROVIDED it is supportable. We have 'supposed' professional pilots posting here who would argue that 'inconveniencing' the company by so doing or not tankering is 'career threatening. Thank the Lord we still have some pilots who put safety before salary..
