NWDs and blackout days
Nonworking days (NWDs) and blackout days indicate reduced capacity of a location to house an aircraft or perform maintenance.
| Day type | Description | Color on Gantt chart |
|---|---|---|
| NWD | A day on a specific track during which no maintenance is completed. An aircraft may sit on the track on a non-working day, but it cannot arrive or be released. Non-working days are sometimes called "plan across days." A holiday, such as Labor Day, is a typical example of a NWD. | Gray |
| Blackout | A day on a specific track during which no maintenance is completed and an aircraft may NOT sit on the track. |

The scheduling engine will enforce these days when generating or scheduling a plan, however, you can override them.
When dragging visits over non-working days, the end date of the visit will extend or retract to maintain the number of working days. This change is not enforced, and you can choose to modify the span of the visit either on the Gantt, or in the Visits Details window, which could result in fewer working days than originally planned. When dragging visits over blackout days, the visit span will remain the same.
You can create and edit NWDs on the Business Rules page.
