Of course the precipice comes at three years, where EASA recommends (but not mandates) that a full type rating course is required for renewing a type rating. This used to be five, and I would like to see the three year precipice removed (or at least made less precipitous)! I have heard some training providers are using discretion to make the refresher training significantly less than a full course, where appropriate, up to a limit of five years.
