Hmmm... interesting
A while back I remember reading somewhere that a pilot submited flight logbook details to the CAA in a Skylog program, the CAA rejected them and asked to see the paper logbook. Although they say that the CAA accept them, I think they do, BUT along side a traditional logbook. I stand to be corrected on this one though.
I myself store all my logbook details on computer, I find it more efficient and even looks better !
