# How to Use the Maintenance Forecast
> View upcoming maintenance events, calendar schedules, and identify overdue or critical items across your fleet.
By following this guide, you will use the maintenance forecast to view upcoming maintenance
events, identify overdue and critical items, plan aircraft downtime around scheduled
inspections, and coordinate maintenance with flight operations.
**Who should read this:** Directors of maintenance, maintenance planners, maintenance
controllers, and operations managers who need to coordinate aircraft availability with
scheduled maintenance.
**Required permission:** `maintenance_ops` -- read to view the forecast.
**Regulatory basis:** 14 CFR 135.411 requires each certificate holder to have an inspection
program and a program covering other maintenance, preventive maintenance, and alterations.
Effective forecasting ensures compliance with scheduled inspection intervals per
14 CFR 91.409 and the operator's approved maintenance program.
## The Forecast Dashboard
Navigate to **Maintenance > Forecast** to open the maintenance forecast. The dashboard
provides a consolidated view of all maintenance obligations across the fleet.
### Summary cards
The top of the page displays:
| Card | What it shows |
| -------------- | -------------------------------------------------------- |
| 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 |
| Upcoming | Items due beyond 30 days but within the forecast horizon |
### 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
Each block shows the aircraft registration, item name, and due date. Click any block to
open the underlying due item or work order detail page.
### 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:
1. Click the item to open its detail page
2. Assess whether the aircraft can continue to operate within any applicable tolerance
3. Create a work order to address the item, or link to an existing work order
4. If the item exceeds tolerance, ground the aircraft until the maintenance is completed
Operating an aircraft with overdue maintenance items beyond the applicable tolerance may render
the aircraft unairworthy per 14 CFR 91.7. Always review your maintenance program and applicable
tolerances before authorizing continued operations.
## Plan Maintenance Downtime
Use the forecast to plan efficient maintenance windows:
### Identify clustering opportunities
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.
### Create a work order
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.
### Set scheduling dates
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.
### Coordinate with operations
Share the forecast view with operations managers and dispatchers so they can plan flight
schedules around planned maintenance windows.
Review the maintenance forecast weekly during your maintenance planning meeting. Monthly, produce
a 90-day look-ahead to identify major inspections and coordinate parts procurement, hangar space,
and technician availability in advance.
## 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.
