Class rating length of validity
I'm studying Air Law at the moment, the book i'm reading explains that a SEP class rating is valid for a period not exceeding 24 months.
However
I have signed up to Airquiz.com and the answer they are giving is that they are only valid for a year. I've looked at LASORS but they only seem to explain how to renew, 12 hours flying etc etc ... maybe I cant see it for looking.
Can anybody confirm how long SEP class ratings last.
Thanks V much
