This is an old revision of the document!
The report is divided in 2 main columns:
You can select a date range 'From - To' or a particular month, as well as data source in the filter (plan, available, journey logs).
Apart from flights, this report also shows duties added in the Crew Duties section. If the duty is on the aircraft, Leon shows an aircraft type and also duty defined code (in a section Settings > Duties Setup).
