Unmanned Aircraft Flight Manual
the radar module can measure the spraying distance above the vegetation or other surfaces, but the
aircraft is not able to y at a constant spraying distance. Obstacle avoidance can be used in any mode.
Auto Obstacle Avoidance is disabled by default. Users can enable it in the app.
Detection Range
The obstacle detection distance of the omnidirectional digital radar is 1.5-30 m while the upward radar
has a detection distance of 1.5-15 m. The FOV of the system is shown in the gure below. The aircraft
cannot sense obstacles that are not within the detection range. For the four gray areas in the gure, the
detection performance of the radar module may be reduced due to the obstruction of the frame arms
and landing gear. Fly with caution.

The effective detection distance varies depending on the size and material of the obstacle.
When sensing objects such as buildings that have a radar cross section (RCS) of more than -5
dBsm, the effective detection distance is 20 to 30 m. When sensing objects such as power lines
that have a RCS of -10 dBsm, the effective detection distance is approximately 15 m. When
sensing objects such as dry tree branches that have a RCS of -15 dBsm, the effective detection
distance is approximately 10 m. Obstacle sensing may be affected or unavailable in areas
outside of the effective detection distance.
Omnidirectional Digital Radar Usage
Obstacle Avoidance Function Usage
Make sure the horizontal obstacle avoidance function of the radar module is enabled in the app.
Obstacle avoidance is used in the following two scenarios:
1. The aircraft begins to decelerate when it detects an obstacle is 15 m away and brakes. While
braking, users can not accelerate in the direction of the obstacle but can y in a direction away from
the obstacle. The aircraft will hover in place if the user does not perform any action. Fly in a direction
away from the obstacle to regain full control of the aircraft.
2. The aircraft immediately brakes and hovers if it detects an obstacle nearby. Users cannot control the
aircraft while it is braking. Users can y in a direction away from the obstacle to regain full control of
the aircraft.
Altitude Stabilization Function Usage
1. Make sure that you have enabled the altitude stabilization function of the radar module in the app.
2. Enter the desired operation mode, and congure the desired spraying distance.
3. If the operating environment is ideal, the aircraft ies above the vegetation at the preset height.
