Terrain Follow System

Profile

The Terrain Follow System is consist of forward, rear and downward radar modules and uses

microwave technology for terrain following. Under optimal operating environment, the system

can predict the distance between the aircraft and the crops or other surfaces in forward, rear and

downward directions, so that the aircraft can fly at a constant spraying distance from them to

ensure even spraying. The radar module is enabled by default, and can be disabled in the app. If

it is enabled, the aircraft will fly above the crops at a constant spraying distance in Smart Operation

Mode and Manual Plus Operation Mode and F-mode. The system can also measure the spraying

distance above the crops or other surfaces, but the aircraft will not be able to fly at a constant

spraying distance when performing this function in Manual Operation Mode.

How to Use

1. Ensure that the Terrain Follow System is enabled in the app.

2. Configure the desired spraying distance (between 1.5 and 4.5 m) in the app.

3. If using Smart Operation Mode or Manual Plus Operation Mode, ensure that the Flight Mode

Switch is toggled to “P” position and the Operation Mode Switch is toggled to “M” position.

If using F-mode, ensure that the Flight Mode Switch is toggled to “F” position. Fly the aircraft

above the vegetation and adjust the distance between the aircraft and the vegetation to a value

within the working range (1.5 - 4.5 m).

4. Toggle the Flight Mode Switch and Operation Mode Switch to the desired position to enter the

corresponding mode. If operating environment is ideal, the aircraft will fly above the vegetation

at the pre-set height.

The Altitude Stabilization System will only maintain a fixed distance from vegetation

within its working range (1.5 - 4.5 m).

Observe the aircraft’s distance from the vegetation at all times.

Operate with extra caution when flying over inclined surface.

Obey local radio transmission laws and regulations.
