Having seen the FI revalidation 'assessment of competence' requirements (which now take an entire day, it seems)
Could this be perpetuation of gold plating? It was clearly not intended by EASA:
GM1 FCL.1015 Examiner standardisation
(a) An examiner should plan per day not more than:
(1) three tests or checks relating to PPL, CPL, IR or class ratings;
(2) four tests or checks relating to LAPL, SPL or BPL;
(3) two tests or checks related to CPL, IR or ATPL;
(4) two assessments of competence related to instructor certificates;
(b) An examiner should plan at least 2 hours for a LAPL, SPL or BPL, 3 hours for a PPL, CPL, IR or class rating test or checks, and at least 4 hours for FI, CPL, IR, MPL, ATPL or MP type rating tests or checks, including pre-flight briefing and preparation, conduct of the test, check or assessment of competence, de-briefing, evaluation of the applicant and documentation.
