Since the glider has no recording tach or Hobbs it's been a habit of mine
for decades to keep the log in the glider where I can keep it current after
each flight.
My glider is registered Experimental and the Operations Limitations state that
the log book must be kept in the aircraft.
I specifically asked the FAA whether I had to log immediately after every
flight or could just update periodically. He said periodically was fine.
Consequentely, my partner and I only update the logbook once a year at annual
inspection.
