Cold weather battery preheating, voltage monitoring, and compass calibration pitfalls at high altitude.
高原无人机实战指南：5000米海拔下的电池管理、飞控逻辑与安全拍摄技巧
Operating drones at altitudes above 4,000 meters presents unique challenges due to thin air, low temperatures, and magnetic anomalies. This guide provides a deep technical analysis of the "voltage cliff" in Li-Po batteries, emphasizing the need for pre-heating and monitoring voltage over percentage. It details the aerodynamics of thin air, explaining why high-altitude propellers are essential to prevent motor overheating. Furthermore, it explores flight control risks like ATTI mode drift caused by magnetic interference and provides professional cinematography strategies, such as using Manual White Balance and telephoto lenses to safely capture glaciers like Laigu without risking the aircraft.
