And you do of course have the option of keeping it electronically and having it do all the work.
Handy when you need a total of say instructional hours teaching ex 27 (instruments) or somesuch strange query.
I know a lot of people really don't like the idea of an electronic logbook, but If you print out the last page once a week, and file it when the page is full then you still have a hard copy.
I've done the last four years without writing a single thing apart from my signature on the bottom of each page.
Can also be labour saving if you only work for one company and can extract the flight hours from their computer system, you can end up not even typing in your logook.
