Exploring the Advanced Flight and Spraying Mission Modes of the DJI Agras T40 Drone

The DJI Agras T40 drone is a revolutionary agricultural drone that offers a variety of

advanced flight and spraying mission modes to help farmers maximize their crop yield and manage their farmland more efficiently. This article will dive into the different flight modes and spraying mission modes of the DJI Agras T40 drone, highlighting its capabilities and benefits for agricultural professionals.

Flight Modes:

  1. N-Mode/F-Mode (Normal): The DJI T40 drone operates in N-mode by default, using GNSS or the RTK module for precise positioning. When the GNSS signal is strong or the RTK module is enabled, the drone provides centimeter-level positioning accuracy. In the event of weak GNSS signals or compass interference, the drone reverts to A-mode.

  2. S-Mode (mapped to A-Mode, Attitude): In S-Mode, the T40 drone relies on the barometer for altitude maintenance without using GNSS for positioning. It is more susceptible to environmental factors and requires more skill to maneuver. A-mode should be avoided in confined spaces or areas with weak GNSS signals.

Spraying Operation Modes:

  1. Route Operation Mode: In this mode, the DJI Agras T40 follows a predefined route generated by the user-inputted field data, obstacle locations, and prescription maps. The drone supports connection routing and operation resumption, as well as altitude stabilization and obstacle avoidance. Route Operation Mode is ideal for large spray areas.

  2. A-B Route Operation Mode: The A-B Route mode follows a pre-planned square zig-zag pattern, turning at recorded points A and B. This mode is recommended for large, triangular, or rectangular spray areas and supports operation resumption and data protection, as well as altitude stabilization and obstacle avoidance.

  3. Manual Operation Mode: Manual mode allows the user to control all movements of the aircraft and manually adjust the spray rate. This mode is ideal for small operating areas where precise control is necessary.

  4. Manual Plus Operation Mode: Manual Plus mode offers a locked heading and manual control of all other movements, with the option to disable heading lock in the settings. This mode is suitable for irregularly-shaped operating areas and provides altitude stabilization and radar module support.

  5. Fruit Tree Operation Mode: Fruit Tree mode uses operation information downloaded from DJI Agras Intelligent Cloud or imported from a microSD card. In this mode, the drone follows a predefined operation, with options for rotary spraying and adjusting parameters such as spray amount, flight speed, and height above vegetation.


The DJI Agras T40 drone's versatile flight modes and spraying mission modes make it an indispensable tool for farmers and agricultural professionals. Its advanced features, such as Dual Atomized Spraying System, Active Phased Array Radar, and Binocular Vision, combined with its intelligent flight and spraying modes, enable users to maximize crop yield and optimize their farmland management. By understanding and utilizing the T40 drone's capabilities, agricultural professionals can unlock its full potential for their farming operations.
