Revalidation
DFC,
Just for your information, it is not a prerequisite in JAA-FCL that the instructor signs your logbook. It suffices when the rating validation page of the license is signed by the instructor. The endorsement in the logbook is a practice in the FAA environment. After conducting a BFR, the FAA instructor endorsed the logbook. I guess this is because the FAA license has a credit card format and hence provides no possibilities for extensions.
