If has anyone some ideas for what reason this log is useful please post your thoughts.
Chris,
Although I don't keep serious aircraft records, I know that a lot of people do. However, I do like to see which aircraft I have picked up, especially when I am not watching the RB screen. I like to follow military aircraft, even though I can't see these on the screen. My log should be able to tell me which aircraft I have seen in the past and which ones today. Also, I'm currently interested in following the new A380 aircraft. With a good database (log), I should be able to see when I have picked these aircraft up, how many times I have "seen" them and when a new aircraft appears.
Without a good database, RB is an interesting thing to look at - with a good database, RB becomes a useful tool to support a very interesting hobby.
I hope that this helps. I'm sure that there will be others who will reply to this to tell you just how they use their logs.
All the best
