The instructor hour is broader than it used to be:
refresher training of at least 1 hour of total flight time with a flight instructor (FI) or a class rating instructor (CRI). Applicants shall be exempted from this refresher training if they have passed a class or type rating proficiency check, skill test or assessment of competence in any other class or type of aeroplane.
The experience requirement which must also be in the last 12 months is measured up to the end of the extension and not the original last 12months.
