UAV standard operation procedure (take DJI drone as an example)

Pre-flight preparation

1. The UAV is assembled before flying. Assemble the wings, fuselage, landing gear. At the same time, check whether the fuselage and propellers are damaged. Replace them in time if damaged.

2. Check the battery level and install the battery.

Start flying

1. Switch on the drone

First turn on the remote control, and then turn on the drone. Short press the power button once and then long press it for three seconds to turn on.

2. Check whether the remote control is connected to the drone normally, and whether there is any error reported on the remote control panel. Whether the UAV system firmware has been updated? Does the remote control report an error? Is the flight mode selected correctly (attitude mode, GPS positioning mode)?

3. After the remote control reminds that the return point has been refreshed, please pay attention to the prompt sound of the return position, start the drone with pushing the joysticks of the remote control to in-toeing direction. Make sure that the surrounding environment of the drone is safe before taking off the drone.

(To use the remote control in American-hand mode as an example: the left joystick controls the up and down as well as left and right rotation of the drone. The right joystick controls the movement of forward, backward, left and right directions of the drone respectively.)

In flight

1. Check the flight path for obstacles, and avoid them in advance if you find them.

2. Pay attention to the battery power. If the power is low, you need to return in time. Pay attention to the connection signal of the remote control. If the connection signal is found to be weak, it is necessary to adjust the flight trajectory in time to shorten the distance between the drone and the remote control until the connection signal is restored.

End flight

1. Check the landing area to ensure that there are no obstacles and the landing ground needs to be flat.

2. UAV landing: During the landing process, the speed needs to be slowed down. After the drone touches the ground and the propellers stop turning, the landing process is completed.

无人机操作流程（以大疆无人机为例）

飞前准备

1无人机飞前组装。组装机翼，机身，起落架；同时检查机身、桨叶是否有损坏，如有损坏需及时更换。

2检查电池电量，安装电池。

开始飞行

1启动无人机

先对无人机遥控器开机，再对无人机机身开机。

2 检查遥控器与无人机是否连接正常，遥控器面板有无报错。无人机系统固件是否更新完成。遥控器是否有报错。飞行模式是否选择正确（姿态模式，GPS定位模式）

3听到遥控器发出返航点已刷新，请留意返航位置的提示音，遥控器摇杆内八启动无人机。确保无人机周围环境安全的情况下，再起飞无人机。

（遥控器以美国手为例：左侧摇杆,前后控制无人机的上升和下降，左右控制无人机的左右旋转。右侧摇杆，前后左右分别控制无人机的前进、后退、左平移和右平移）

飞行中注意

1检查飞行路径是否有障碍物，如发现障碍物需提前躲避。

2注意观察电池电量，电量不足需要及时返航。注意观察遥控器连接信号，如发现连接信号变弱，需及时调节飞行轨迹，缩短无人机和遥控器的距离，直至连接信号恢复。

结束飞行

1检查降落区域，确保降落区域没有障碍物，降落地面需要平整。

2无人机降落：降落过程中，需要放慢速度。无人机下落到地面，直至无人机螺旋桨停止转动。
