Currently we answer quite a few questions from AOPA members through referring to the excellent CAP804...
For some inexcusable reason, it wasn't updated to take into account the latest changes both to the Aircrew Regulation and ANO2016. It should be an on-line live document, updated with each and every regulatory change at the time it takes effect.
As the CAA has cut the number of its staff to the bone, they may well now find more and more queries being directed to them (not to fclweb, but to the top level of the CAA!) if they don't sort out CAP804...or LASORS 2017...or even CAP53 / 54.
Their choice.
