Currency requirement for us is having flown in the last 28 days, if thats not the case we need at least one day of supervision with at least one manual landing.
Next requirement is of course the 3 landings in 90 days, but thats rather easy flying shorthaul.
Next bigger thing is every 6 months a SIM check and a LOFT session (actually first LOFT, then the check) covering the low visibility stuff as well, all systems have to be covered within a three year period.
Once a year we have to do a written test about systems and procedures, additionally there is the dreaded SEP training with a written test as well, of course we have to do one day of linetraining as well. Linecheck is to be rostered so that both crewmembers are from different bases and it has to contain at least one international sector (yes, we do fly a lot domestic stuff). We do have to do a test about workplace security, radiation security stuff etc once a year as well, just computer click and point stuff.
Every second year we have to do firefighting training and dangerous goods training and tests.
And i guess that about covers it, apart from passing the medical of course.
