DFC - great answer thanks.
My logbook is actually a Jepp that is JAR-FCL 1.080 compliant so I didn't think I would have had to buy an 'old standard' logbook to remain compliant.
I haven't had it long and never saw the section at the back. Explains it all.
As it happens, it was the recent circular on student IR flight time that prompted me to check that I was fully compliabnt.
cheers
