I remember this 3 month/12 month question coming up at an instructor refresher seminar three years ago.
I was adamant that it was 3 months - was beaten into submission (by ppruner "BlueLine") that it was 12 months.
I would expect that the Lasors 2005 is a typo, rather than a policy change (we've all seen some fun non-proof read material from Battleship House [anybody seen the new Form172, CPL Skill Test Report]).
Who has a current copy of FCL1 for the correct answer?.
