 Each configured sensor reports the flight count as its state and exposes detailed flight data through the `flights` attribute.
 
+## Known Limitations
+
+- This integration mirrors the public Avinor flight feed and does not supplement missing airport data from other sources.
+- Avinor documents that the service does not include data from private airports such as Sandefjord Airport, Torp (TRF).
+- Private airports may therefore show incomplete, delayed, or missing arrivals and departures even when the integration is working correctly.
+
 ## Flight Details (Airlabs)
 
 This integration can optionally fetch details for a specific flight from the Airlabs Flight API:

 ## Release Notes
 
+- **1.0.9**
+  - Documented the upstream Avinor limitation for private airports such as TRF/Torp.
 - **0.2.1**
   - Split the Lovelace card into its own repository.
   - Updated HACS/Hassfest workflows to meet current validation requirements.
