Hi,
so I have been looking at the DCS shortly and on the logbook file. But is is not designed even the similar way like logbook for civil flight simulator. There is an overall statistics with total time, day time, landings, than some kills and other military stuff. Than there is similar statistics for every aircraft. So unfortunately, not really possible to move it on civil flight logbook which is base around flights, origin and destination airports etc. since these data simply are not there. This is at least true for the single player. For multi-player, I guess the statistics would be stored somewhere on their server, so you cannot manipulate them easily :) (Which in single player, you can by editing logbook.lua in Documents\Saved Games\DCS\MissionEditor folder). To summarize, the support for DCS in FS Logbook Editor is sort of meaningless, would require too many exceptions and bending of the program for low added value, I think.
