Avenger is not correct. what he is referring to is an AMC (Acceptable Means of Compliance). It is still completely up the the ATO that evaluates in accordance with Paragraph (b)(1) of FCL.740. There are alternate means of compliance, and that is the ATOs job to figure out how much training is required. Just renewed a rating on an aircraft I haven't flown in 14 years after having an individual training plan created by an ATO and then accepted by the Authorities that issued my license, my individual plan was three sim detailed sim session followed by a skill test.
It is important to NOT read an AMC as they are the rule, they are guidelines. Not all authorities has understood this completely and stick to what the guideline (AMC) from EASA suggests.
