This is interesting and new though:
*2) Provided that within the preceding 12 months the applicants have flown at least three IFR departures and approaches exercising PBN privileges, including at least one RNP APCH approach on an SP class or type of aeroplane in SP operations, or, for multi-engine, other than HP complex aeroplanes, the applicants have passed Section 6 of the skill test for SP, other than HP complex aeroplanes flown solely by reference to instruments in SP operations.
For all those RNP & PBN PA28's out there! Makes it slightly more tricky to keep current.
