Hi Peter,
I like to report an error loging, everytime I loose gps signal, log book close log, and back open new log again when gps signal come back.
My suggestion is that the logbook should ask the user for confirmation weather to close or leave it running.
Request, logbook is link to the tracking function, which I believe it should be independent features.
What I'm saying is to be able to activate auto loging with out turn on tracking function and vice versa.
It is very nice to have a flight log all the time, and save automatically.
Let me know if any question.
Thanks
