As a reasonably busy CRI who gets a bit fed up of the proportion of FIs who look down their noses at me, I'd like to see parity of requirement - that way I can demonstrate that I have to meet the same requirements that they do.
As a great fan of evidence based policy making, I'd like to see the evidence for either in ensuring competence in flying instruction.
As a pragmatist - right now as a CRI I'm flying a reasonable number of annual instructional hours, and would have to do a test every 6 years anyhow. So this change would require me to do either another test or a seminar halfway between those 6 yearly tests. So the real impact would be minimal.
So, let's see the evidence - and then standardise all of us on the minimum shown necessary to ensure good instructing standards.
