CorpAv8R,
Please make sure your aircraft are properly configured in view..options..aircraft. There is no need to have jet, turbine, complex, etc column. Logbook Pro tracks this and more based on those configurations.
To find your turbine time
Select..view..analyzer and all data
Now click on the blue (Power Characteristics) filter near the top and uncheck any non-turbine options
click back into the analyzer and you will see Total Duration = Total Turbine, and PIC = TURBINE PIC with the filter set.
There isn't a way to make a bulk edit for what you are trying to do. However, you can find the same total in the analyzer using filters.
Select..view..analyzer and all data
Click on the blue Aircraft Make/Model Filter and UNCHECK all your single pilot aircraft
Click back into the analyzer and it will now just be showing your totals for 2 man aircraft that you left checked...
