I have this logbook, and something I think doesn't help, is that when you click "enlarge image" on that link it actually cuts off the end 2 columns of the logbook. These columns are for you to note take offs and landings both day and night. Once you open the enlarged imagine, expand to full screen and you'll see what I mean. So all someone has to do to see if someone is current to take pax, is look back 90 days as of the current day in the logbook, and see where the owner of the logbook has logged at least "3" total in that column and was PIC.
