Milo,
If the AW139 instructor job in Italy is for AW, and you are interested in applying, then you should go into it with your eyes open. I know that in the past AW has promised instructors that they will do a mixture of synthetic and actual flying instruction, and said instructors then find that the only instruction they are offered is in the sim. Also, I know that the work rota has not always been quite what it appeared to be at first...
