| Overdue | Items past their due date, hours, or cycles — red |
| Due This Week | Items coming due within the next 7 days |
| Due This Month | Items coming due within the next 30 days |

Calendar view
The calendar displays maintenance events as colored blocks on a timeline:- Red blocks — Overdue items requiring immediate action
- Amber blocks — Items due soon (within warning threshold)
- Blue blocks — Scheduled work orders with start/end dates
- Green blocks — Completed items in the current period
Fleet timeline
The fleet timeline view shows all aircraft on the vertical axis and time on the horizontal axis, with maintenance events plotted for each tail number. This view makes it easy to identify periods when multiple aircraft are simultaneously down for maintenance and adjust scheduling accordingly.Filter the Forecast
Use the toolbar filters to narrow the forecast:- Aircraft — Show events for a specific tail number
- Category — Filter by maintenance category (inspection, AD, component, engine, etc.)
- Priority — Filter by item priority (low, normal, high, critical)
- Date range — Adjust the forecast horizon
- Status — Show only overdue, due soon, or upcoming items
Work with Overdue Items
Overdue items appear at the top of the forecast with red indicators. For each overdue item:- Click the item to open its detail page
- Assess whether the aircraft can continue to operate within any applicable tolerance
- Create a work order to address the item, or link to an existing work order
- If the item exceeds tolerance, ground the aircraft until the maintenance is completed
Plan Maintenance Downtime
Use the forecast to plan efficient maintenance windows:Look for due items on the same aircraft that fall within a close time window. Grouping
maintenance tasks into a single downtime event reduces aircraft out-of-service time.
From the forecast, select items to group and click Create Work Order. The work order
is pre-populated with the selected items and the aircraft registration.
Enter the planned start and end dates on the work order. These dates appear on the forecast
calendar as a blue block, making the planned downtime visible to the entire team.
Calendar Note Items
Due items with the Add to Calendar flag enabled appear on the forecast calendar automatically. Toggle this flag on items that are important for scheduling visibility but might otherwise be buried in a long list.Manage Due Items
