We basically do a sim qualification which includes limiting take offs, RTO's, engine failures etc for the take off case and approaches including missed approaches, landings, and failures including continue and go around cases. We then do 3 approaches in the aeroplane using autoland but in better conditions.
During the sim chekcs we have a stand alone AWOPS section doing the above sort of stuff again and we have to do 2 auto approaches between sims - or do more approaches in the sim.
AWOPS remains a discrete qualification but in practice forms part of the sim check and is not difficult. Its nothing to worry about.
Failure cases are easy to deal with in the main, its usually one descision - go around or land and you follow the usual pattern.
Having said that, I don't fly the Airbus so there may well be differences I am unaware of.
