Operating System
Global Filters and Time Modes
Set the baseline logic for a dashboard using time modes, category filters, and affected-element filters.
Global settings are the baseline for the whole dashboard. They should do most of the filtering work.
Time modes
| Mode | Best for | Example |
|---|---|---|
| Absolute | Fixed briefing windows | A single departure bank |
| Relative | Rolling monitoring | Next 3 hours from now |
| Daily | Repeating operational windows | Every day, 04:00 to 10:00 UTC |
| All active | Full current-state view | Operations center wallboard |
Set the time mode first in the dashboard header.
Category filters
Category filters narrow the dashboard to specific NOTAM domains. Use them when the dashboard exists to watch a type of operational change (e.g. aerodrome, airspace, navigation).
Notamify classifies every NOTAM into one of 42 predefined categories.
Affected element filters
Affected element filters select NOTAMs by operational consequence:
- Closed runway
- Unavailable fuel service
- Restricted aerodrome
- Unserviceable navaid
See Atomic Elements for the full list of element types and effects.
Recommended approach
- Set the time mode.
- Add the minimum global filters needed.
- Review the results.
- Add airport-level overrides only where the baseline is too broad or too narrow.
Starting with overrides too early makes the dashboard harder to understand and maintain.
Next step
Continue with Airport Overrides and Views once the global baseline is stable.
