Any specific ways you stay up to date with your ATPL KNO?
Passed all the ATPL exams and now in VFR phase. I notice that my ATPL knowledge starts degrading. I like to keep it current because this stuff resurfaces in checks, IR, type rating theory, interviews. I find it quite hard to start reading again as it is a lot of material. Anyone has a specific approach, like an app or cards, or just reading the books?
