Hi
My biannual is due in March this year. I've completed way over the 12 hours for revalidation, PLUS have done a couple of flights with an instructor, which I believe exceeds the requirement.
However, the instructor hasn't signed my logbook for these flights. Does he have to do this, AS WELL as sign the revalidation form for the CAA, or doen't it matter, because it shows clearly on the aircraft log sheets?
