Low latency and reliable connectivity are essential for live video streaming from helicopters in mission-critical scenarios, such as search and rescue missions and law enforcement activities. This paper addresses the challenges of achieving low latency and reliable connectivity for live video streaming from helicopters in mission-critical scenarios. We propose a location-based adaptive model leveraging bonded LTE and 5G cellular networks to dynamically adjust to varying cellular network conditions for aerial connection. Additionally, a packet-delay sliding-window (PDSW) channel model is presented for live video streaming from helicopters, along with a practical location-based adaptive Forward Error Correction (FEC) system to enhance error correction efficiency. Experimental results demonstrate the effectiveness of the proposed approach in mitigating packet loss and ensuring reliable video streaming from helicopters.
