RodgerF Me too....
Ive always been happy with the fact that what I get charged and what is logged are two different things.
With regard PIC and responsiblity - they are both defined in the ANO/JAR-FCL as well - and you are actually PIC/responsible before flight time starts
The RAF use airbourne times - which always seemed sensible to me - I never have worked out why civilian world uses block time.....but thats the way they want it logged....
On another note - I actually used a Jeppesson logbook (and still do) pre and post JAR. However, I have always written down the times of departure & arrival.
Just because your logbook doesnt have a column for it doesnt mean you cant write it down - and therefore be JAR compliant regardless of weather or not the logbook is JAR compliant. The law mean requires you to keep a logbook and to maintain certain details about the flight...

FF
