review sufficiently far back
- there, in my flying career, has been the problem. The overwhelming need to remove the top copies at base so that the eng computer can be updated, leaving sometimes undecipherable (limp wristed writers

) copy pages and bingo - you sometimes don't have a clue. I was under the impression that somewhere in the regs (UK) was a 'never followed' requirement to ACTUALLY transfer PRF's to the active page?
