We had a CFII here not long ago (Miguel) and he gave us that information.
I take your point, John, but they are linked. Continuation and checking is fine if you get the standards right, but they are not necesasrily here in UK. I have mostly worked for small companies in Canada, over a space of over 6 years, and from TC inspector to DFTE I've had more consistent check rides than anywhere. But then, that was some years ago
.
Before JAA, base checks (6 monthlies) used to be done at 90% MAUW, and I think it's a shame that it stopped.
