11. Merged Feeds

1. Purpose 
 Merged Feeds build one logical output from multiple source feeds. 
 Recommended model: 
 
 keep physical sources in Feeds , 
 expose combined output via merged feeds where needed. 
 
 2. Merged feed options 
 Each merged feed has: 
 
 Name 
 Source Feeds ( receiverIds ) 
 Enabled 
 Visible in Radar Dropdown 
 ICAO Timeout (ms) 
 Ignore Aircraft with No Position 
 
 3. Runtime logic 
 For each ICAO: 
 
 one source feed is selected as active owner, 
 duplicate frames from other sources are suppressed, 
 if active source is silent longer than ICAO Timeout , ownership may switch to another source. 
 
 4. ID namespace 
 Merged feed IDs use dedicated range starting from 10000 , reducing collision risk with regular feed IDs. 
 5. Workflow notes 
 
 Feed editor contains shortcut Add to merged feed for smart-profile ports. 
 Final source assignment should be verified in Merged Feeds panel. 
 Merged feeds can be selected as source in Rebroadcast Servers .
