Hello Tim, sometimes it happens that an user accidentally do not close the log. Than this logs also logs the journey home by car. Is it possible to split the log, so that the user can remove the non flight times?

The merge option works great (Maintenance -> Merge with Another Log). A split option in the same manner would be excellent.

Other users I talked to had more than once the same problem like me.

Flight log files are in a binary format and are not designed to be user-editable.
