Drone:
A kind of aircraft driven by power, unmanned on board and reusable, with multiple control methods such as remote control, semi-autonomous and autonomous flight.
Safety:
No accidents, no harm and no threat.
Lost stars:
It refers to the loss of GPS signals. During the flight, the "drone" flies to a place with a strong magnetic field and is disturbed, or the GPS signal is blocked, making it impossible for the flight control system to achieve precise positioning.
Aerial parking:
It generally refers to the situation where the motor or engine of a drone stops rotating when it is in flight in the air.
Flight control:
Known as the brain of a drone, the flight control system of a drone mainly consists of a gyroscope (flight attitude perception), an accelerometer, geomagnetic induction, a GPs module, and a control circuit. The main function is to automatically maintain the normal flight attitude of the aircraft.
Passage:
The most common term for a remote control indicates several signal patterns, with one channel corresponding to one signal, which enables the aircraft to perform corresponding actions.
2s, 3s, 4s batteries:
S represents the series connection of batteries. The standard voltage of one lithium battery is 3.7V and the full charge voltage is 4.2V. The standard voltage of the high-voltage plate battery is 3.8V and the full charge voltage is 4.35V.
Battery c parameters:
It represents the battery's discharge capacity, which is the most significant difference between ordinary lithium batteries and power lithium batteries. Power lithium batteries require a large current for discharge, and this discharge capacity is represented by c. If the battery capacity is 10Ah and the standard is 5C, then using 5x10A, it is concluded that the battery can discharge at a current of 50A.
General weather information
The main meteorological conditions that seriously affect the flight of unmanned aerial vehicles are:
Heavy rainfall weather may be accompanied by lightning and ice and snow strikes, wind shear and turbulence, which can deteriorate the aerodynamic performance of aircraft, cause excessive load on electric motors and even burn them out. Ice accumulation: Aircraft ice accumulation mainly falls into three categories: ice, rime, and frost. Mild icing may affect the performance of the aircraft. If the ice does not accumulate, the aircraft can continue to fly, but the flight time will be significantly reduced. If the aircraft reaches moderate or severe icing, it should immediately change course or land.
Visibility: When the effective visibility at the flight site is too poor, aircraft are prohibited from flying.
Visual range: When encountering visual range obstacles during flight, that is, visual range obstacle weather, one should change course and land as soon as possible to avoid unnecessary losses. Mountain air currents: The main impact of mountain air currents on aircraft is the influence of vortices. When flying in mountainous areas, one should increase the safe altitude of the flight path and pay attention to the mountain air currents. Wind shear occurs, and the wind direction in mountainous areas varies greatly. When taking off, taking flight routes, and landing, one must pay attention to the wind conditions at that time.
Battery energy saving program
Ensure that the software version of the flight controller is the latest one.
2. Before takeoff, adjust the aircraft parameters according to the takeoff weight and adjust the flight speed in accordance with the manufacturer's guidance and suggestions.
3. Reduce rapid maneuvering actions, minimize hovering time in the air, and reduce the time spent running the aircraft against the side wind.
4. Reduce the operation time at high altitudes.
5. In extremely cold regions, please use the battery temperature management system.
High-altitude operation (8,000 feet, 2,438 meters and above)
When unmanned aerial vehicles (UAVs) operate at high altitudes, the load on the power system is relatively large, which may cause the aircraft's power system to overload and burn out the electrical and mechanical control systems. It is recommended to ensure that the aircraft operates within a safe altitude range. If operating at high altitudes, please reduce the load weight and operation time, lower the aircraft's climbing and descending rates, increase the turning radius, and reduce or prohibit large maneuvering actions.
1. Regarding power loss: When operating at high altitudes, both the electric system and the oil-powered system will suffer partial power loss due to the thin air and reduced atmospheric content, thereby reducing the maximum takeoff weight and standard endurance of the aircraft. Replacing the corresponding propellers can reduce part of the power loss.
2. Regarding electronic devices: When operating at high altitudes, some electronic devices are more prone to corona and discharge phenomena. Please carefully inspect the relevant electronic equipment when operating at high altitudes. 3. Regarding airspeed calibration: When operating at high altitudes, there is a significant difference between the true airspeed and the apparent airspeed of the aircraft. At an altitude of 2,000 meters, there is approximately a 10% difference between the true airspeed and the apparent airspeed. At 400 meters, it is about 20%, and at 500 meters, it is about 30%. When operating at high altitudes, please use the calibrated airspeed to run the unmanned aerial vehicle.
4. Key weather information: The altitude of the plateau airport is high. Due to the strong wind passage at high altitudes, the air close to the ground is heated unevenly in the sunny and shady directions due to the sun's rays. Coupled with the terrain's obstruction and resistance to the wind, strong winds frequently occur at the plateau airport, with significant variations in wind speed and direction, which can easily lead to turbulence, turbulence, and wind shear. Pay close attention to turbulence and wind shear during takeoff and landing. At the same time, it is also necessary to pay attention to the complex and changeable climate of the plateau, with obvious time differences, regional and local characteristics. Please pay attention to the take-off time and climatic conditions.
5. Regarding terrain: In some high-altitude terrains with many mountains, canyons and cliffs, the communication antenna system of the unmanned aerial vehicle (UAV) data transmission link mostly adopts vertical polarization and horizontal polarization polarization methods, which may be affected by the terrain and cause multi-path interference, potentially leading to
The communication distance has been shortened and the communication quality has declined. 6. Regarding low-temperature operation: Cold weather operation mainly affects the battery discharge capacity of aircraft and flight control sensor components. When the battery operating temperature drops below 10 degrees Celsius, the battery discharge curve will significantly deteriorate, causing an unexpected and sudden drop in voltage, which may result in the aircraft losing power supply. At lower temperatures, it can also cause faults in flight control-related sensors. This further affects the safe flight of the aircraft. Please use the heating system when operating at high altitudes. Aircraft are prohibited from flying at extremely low temperatures.
7. Regarding operators: When operating at high altitudes, the battery life of related electronic equipment decreases. The rapid response ability of personnel will be reduced to varying degrees due to less oxygen and lower temperatures. When operating at high altitudes, please pay attention to the combination of personnel. Note: When operating at high altitudes, please replace the corresponding propeller model according to the working altitude (for specific technical parameters, please contact the drone manufacturer).
Operation in cold weather
Cold weather operation mainly affects the aircraft's endurance. When the temperature drops below 10 degrees Celsius, the aircraft's operating time will significantly decrease and the battery discharge curve will noticeably deteriorate, causing an unexpected and sudden drop in voltage and resulting in the aircraft losing power. Therefore, in low-temperature weather, the takeoff of aircraft should be reduced or prohibited.
When operating in cold weather, adding sponge or foam to the gap between the battery and the aircraft can significantly improve the battery discharge curve under cold conditions and extend the operating time of the aircraft.
2. When transporting batteries, please use insulated battery explosion-proof boxes.
When calibrating airspeed, please pay attention to whether the barometric pressure sensor and altitude sensor are abnormal.
Note: For cold weather operation, the battery heating module provided by the drone manufacturer can be optionally equipped as needed.
