Aircraft Filter

Aircraft filters are used in the Gantts to filter the display of the aircraft fleet or only some selection of them. Filters may be used throughout N-OC and can be done on the upper-left corner of the Gantt. They are also available in various dialogs to narrow the list of aircraft when the user only wants to work with a selection (e.g. Maintenance Service dialog). Aircraft filters belong to the data type Vehicle and can be used wherever you have vehicles, such as Schedule, Roster, and Roster Block Gantts.

Aircraft filters is located under Editors > Aircraft > Aircraft Filters or you can search for aircraft and/or filters dialog using the Search field.

The Aircraft Filter Window opens.
