17 October 2026, Beijing: An agricultural drone should be evaluated as part of a farm workflow, not simply as an aircraft with an attractive specification sheet. The useful question is not only what the machine can carry, but whether the people, documentation and support around it fit the intended job.
FAO places sustainable mechanization in a wider context that includes people, machinery and the environmental and social consequences of adopting technology [1]. The procurement questions below apply that perspective to civil agricultural drones. They are a planning checklist, not a flight procedure, product endorsement or report of original field trials.
1. Define the decision or task first
Start with a short description of the job. Is the farm collecting images to guide scouting, documenting field conditions, or considering an aircraft equipped for an application task? These are different workflows. Write down who will use the output and what decision should follow it.
For an imaging proposal, ask how imagery will reach the person making the agronomic decision. For an application proposal, identify the qualified people and separate approvals needed to assess whether the intended use is appropriate. Do not treat an aircraft specification as evidence of agronomic suitability.
2. Describe the fields, not just their total area
Give prospective suppliers a realistic description of the operating environment: the number and shape of fields, access points, nearby activities, available staging areas and the time window for the work. A large combined acreage does not describe the practical differences between one accessible block and many separated plots.
Ask for a proposed workflow and the assumptions behind any productivity estimate. Distinguish time in the air from travel, setup, battery handling, loading, cleaning and reviewing the result. A demonstration should use agreed conditions rather than an unexplained best-case figure.
3. Match the complete configuration to the mission
Request the exact aircraft, battery, payload, controller and software configuration being quoted. Clarify which accessories are included and which require a separate purchase. Ask where the manufacturer documents the operating limits of that configuration.
Treat compatibility as something to verify in writing. Similar-looking batteries, tanks, nozzles or connectors are not proof of interchangeability. DJI’s T30 support material, for example, separates aircraft, battery, spraying-system and component-compatibility information [2]. That is a model-specific example of the documentation to request, not a recommendation to select that aircraft or transfer its limits to another model.
4. Include ground support in the purchase decision
Ask what equipment and trained personnel the proposed workflow needs between flights. Request the manufacturer’s instructions for battery use, charging, storage and inspection, together with the requirements for compatible charging equipment and power supply.
Discuss those requirements with the people responsible for the intended site. A quotation for additional batteries does not, by itself, establish that the farm has a suitable charging or storage arrangement. Resolve uncertainty through the manufacturer or a qualified service provider rather than improvised procedures.
5. Make maintenance and spare parts visible
Before ordering, ask for the current maintenance documentation, inspection schedule and parts identification information. Clarify which work the operator may perform and which tasks require an authorized or otherwise qualified service organization.
Request written information about service contacts, expected parts availability, warranty exclusions and the process for reporting a fault. Ask how serial numbers, replaced components and maintenance actions should be recorded. The objective is to understand the support process, not to promise that any machine will operate without downtime.
6. Assign responsibility for people and permissions
Identify who will coordinate the project, who will operate the equipment, and who will review the output. Ask what training is relevant to the exact aircraft and intended work, and how competence will be assessed.
Check the current requirements with the responsible aviation and other relevant authorities in the country of operation. Application work can raise additional questions that an aircraft vendor cannot resolve simply by supplying hardware. EASA’s European open-category guidance illustrates the importance of operator responsibilities, appropriate procedures and familiarity with the manufacturer’s manual [3]. It is not a worldwide rule or permission for every agricultural mission.
7. Agree on evidence before accepting delivery
Create a written acceptance list before the demonstration or handover. Include the delivered configuration, manuals, software access, parts list, training records and agreed checks. State what evidence will be used to judge whether the proposed workflow meets the farm’s requirements.
For imagery, clarify file formats, access rights, processing responsibilities and any recurring software charges. Do not assume that collecting images automatically provides an agronomic diagnosis. Separate what the equipment produces from the interpretation a qualified specialist may need to provide.
8. Compare the supported workflow, not only the invoice
Ask suppliers to itemize hardware, training, maintenance, software, replacement parts and support. Identify which costs are certain, which depend on use and which are still unknown. Compare buying with the alternative of using a qualified service provider where appropriate.
A useful purchasing discussion ends with documented assumptions and clear responsibilities. When important questions remain unanswered, the next step is further evaluation, not a larger performance claim. The right equipment is the equipment whose intended use, limitations and support arrangements can be understood before it reaches the field.
