Feeds and Merged Feeds

1. Feeds basics

In Feeds, you define physical/logical data sources (Beast, BaseStation, etc.).

For each feed, set:

1. Address and Port
2. Format
3. ConnectionType
4. Enabled

After saving, verify:

1. feed connection status,
2. increasing message counters,
3. non-empty AircraftList.json.

2. Merged Feeds

Use Merged Feeds to build one logical output from multiple sources.

Operating model:

1. Keep raw inputs in Feeds.
2. Publish user-facing output through merged feeds when needed.

3. Feed Filter

Apply filters carefully:

1. First confirm raw input works without filters.
2. Then narrow using ICAO/MLAT and other rules.
3. Re-check list and map after each filter change.

4. Common issue: selected feed still shows too much

Symptom: selecting a specific feed still shows aircraft from other feeds.

Checklist:

1. Verify feedId mapping in output data.
2. Verify frontend sends the correct feed parameter.
3. Compare All feeds vs single feed for the same bbox.
4. Repeat test on a second feed for the same user.
