Lima X-ray - if you did your last test anytime up to Dec 31st 1999, you had the 'old life' term but revalidate or renew the new way when that term is ending. The new way is if you revalidate before expiry you have the 'pick 2 from 3' from the instructional hours, conference, or test. If you let it expire, you must take the conference AND test.
But, Noggin talks about the old way being 2 years (25 months) - my point was that for an AFI, surely it was only a year term from Dec 99. I'd say RVR expired in Dec 2000 UNLESS sometime in 2000 RVR800 did those 'upgrade' hours AND got the supervising instructor to process the upgrade paperwork, in which case RVR800 expires in Jan 2002.
So the key is (as Noggin asks) what is on the rating but also if there was an upgrade, when was it done?
