...which baffled the CFI at my club.
The rules changed over 3 years ago; the relevant AIC was dated 24 April 2008. There was a transition period whilst the new requirements were introduced; this ended on 30 June 2009.
Whatever sort of bone idle club CFI doesn't bother to keep up to date with AICs? It's hardly difficult and there have been plenty of weathered-out winter days when he could have spent an hour or so checking them.
I hate to think what's going to happen when the utter lunacy of EASA hits us all....
