Slight thread drift, but possibly useful info..
I am booked on a CRI course for the purpose of checking out / revalidating SEP ratings of group members of our aircraft, and to hopefully start "putting something back" into the system. Someone also told me that "gaining a CRI will lower your insurance premiums". So I phoned Traffords and asked, the reply was negative.
However, as you are taught to instruct (25 hours theory on instruction) on the CRI course, and have to pass a instructional skills test with a instructor examiner, I am of the understanding it is very much an instructor qualification.
