If an aircraft you’re following suddenly disappears from Flightradar24, it’s typically because our network is temporarily unable to receive a signal from the aircraft. Here are some common reasons for this:
Coverage Gaps: When aircraft fly over areas with limited or no receiver coverage—such as oceans, remote regions, or mountainous terrain—tracking can be interrupted. The aircraft will generally reappear on the map once it enters an area with sufficient coverage.
Transponder and Data Source Limitations: Coverage can vary based on the type of transponder the aircraft uses (e.g., ADS-B vs. Mode S) and the data source. Some transponders work more reliably at high altitudes or in densely covered areas.
Technical Issues and GPS Jamming: Occasionally, technical issues with the aircraft, the receiver network, or atmospheric conditions can disrupt the signal. GPS jamming can also interfere with tracking. You can see more information about current GPS jamming activity and affected areas on our dedicated page here.
Tracking typically resumes automatically when the aircraft reaches an area with coverage again.
