<figure><img src="/files/gqPzjrme7PAuriW6xfgU" alt=""><figcaption></figcaption></figure>

The **Flyability Tether Power Unit** is an optional accessory designed to extend inspection capabilities by providing continuous power between the drone and the ground station. By connecting the aircraft to a ground-based power source, the tether enables significantly longer flight times compared to battery-only operations, making it especially suitable for extended inspections, training sessions, and missions where endurance is critical. The system is engineered to integrate seamlessly with Flyability drones while maintaining flight stability and operational safety.
