• Operator Responsibility: Operators should follow local aviation regulations and manufacturer instructions at all times.

9. General Weather Considerations

Weather conditions can strongly affect drone flight safety, especially for VTOL fixed wing drones operating over long routes or complex terrain.

• Heavy Rain: Strong rainfall may come with lightning, hail, wind shear, and turbulence. These conditions can reduce aerodynamic performance, increase motor load, and may damage the propulsion system.
• Icing: Aircraft icing may occur as clear ice, rime ice, or frost. Light icing can reduce performance and flight time. If moderate or severe icing occurs, change route or land immediately.
• Low Visibility: Do not fly when effective visibility at the operation site is too poor.
• Obstructed Visual Range: If visual range becomes restricted during flight, change route or land as soon as possible to avoid unnecessary risk.
• Mountain Airflow: Mountain airflow can create turbulence and unstable air. Increase route safety altitude when operating in mountainous areas.
• Wind Shear: Wind direction may change quickly in mountains, valleys, and highland areas. Pay close attention to wind conditions during take-off, route flight, and landing.

10. Battery Energy Saving Procedure

Proper flight planning and battery management can help improve endurance and reduce unnecessary power consumption.

• Firmware Check: Make sure the flight controller software is updated to the latest recommended version.
• Parameter Adjustment: Before take-off, adjust aircraft parameters according to take-off weight and follow the manufacturer’s recommended route speed.
• Reduce Aggressive Maneuvers: Avoid rapid turns, sharp climbs, unnecessary hovering, and extended crosswind operation.
• Limit High-Altitude Operation: Reduce operating time at high altitude whenever possible.
• Cold Region Operation: Use a battery temperature management system when operating in cold or high-altitude regions.

11. High-Altitude Operation

High-altitude operation generally refers to flight at 8,000 ft / 2,438 m or above. At high altitude, the propulsion system works under greater load, which may increase the risk of motor or ESC overload.

• Operating Recommendation: Keep the aircraft within the safe altitude range recommended by the manufacturer.
• Payload Reduction: If high-altitude operation is required, reduce payload weight and operating time.
• Flight Control: Reduce climb and descent rates, increase turn radius, and avoid aggressive maneuvers.
• Power Loss: Both electric and fuel-powered systems can experience power loss due to thinner air and reduced air density. This may reduce maximum take-off weight and standard endurance.
• Propeller Selection: Use the appropriate propeller model for the operating altitude. Contact the drone manufacturer for specific technical parameters.
• Electronic Equipment: Some electronic components may be more likely to experience corona discharge or abnormal electrical behavior at high altitude. Inspect electronic systems carefully before flight.
• Airspeed Calibration: True airspeed and indicated airspeed can differ significantly at high altitude. At 2,000 m, the difference may be about 10%; at 4,000 m, about 20%; and at 5,000 m, about 30%. Use calibrated airspeed settings for high-altitude operation.
• Weather and Terrain: Highland areas often have strong winds, turbulence, wind shear, temperature differences, and rapidly changing local weather. Pay special attention during take-off and landing.
• Communication Link: Mountainous terrain, valleys, and cliffs may cause multipath interference and reduce communication distance or link quality.
• Low Temperature: High-altitude regions often have lower temperatures. Use a heating system when required. Do not fly in extremely low-temperature conditions.
• Operator Condition: Operators may experience slower reaction speed due to lower oxygen and cold weather. Arrange personnel properly during high-altitude missions.

12. Cold Weather Operation

Cold weather mainly affects drone endurance and battery discharge performance. When the operating temperature is below 10°C, flight time may decrease significantly, and battery voltage may drop suddenly without clear warning.

• Flight Limitation: Reduce or avoid flight operations in low-temperature conditions when battery performance is not stable.
• Battery Insulation: Adding sponge or foam between the battery and aircraft body can help improve battery discharge performance in cold conditions.
• Battery Transport: Use an insulated explosion-proof battery box when transporting batteries in cold weather.
