I thought it was only smoking that went on behind the bike sheds!
Seriously, the official answer is 1.8 per 1000 feet, and the one I would use in the exam, possibly with a scribbled note as you hand your paper in. As I said it's clearly in the LOs and is obviously what they intend. My comment should have read .... "the answer is wrong, but they still want you to use it."
If I get a chance I will talk to Camelia who I believe still has charge of the CQB - watch this space.....

Just curious - if helipilot22 is using BGS notes, and "a certain school in coventry" uses BGS notes under licence (and if they're not, they're sure both using Framemaker), isn't there a screw up somewhere? Maybe there is a typo between the licence levels.
