Preparing to Field Scout with your Farm Drone

[June 17, 2025]   

Farm drones can be valuable in helping farmers keep an eye on their crops through the growing season. The farmer can carry out tasks efficiently and effectively with proper preparation. Here are some of the basic checks needed to make to ensure a safe and effective flight.

Before Going to the Field

Ensure you are FAA-certified (Federal Aviation Administration). To scout or complete any farm business purposes, the pilot must have acquired FAA Part 107 certification. The certification is valid for two years and is easy to renew.

If your drone has no controller with a built-in flight screen, use an approved device such as an iPad instead of your phone. The larger screen will be much easier to see on bright and sunny days.

Verify with your insurance professional that your farm has adequate insurance for mishaps caused by drone operations.

Plan your scouting flights before going to the field to anticipate needs and potential problems with the drone and the growing crops. Use your sectional maps, apps, and FAA information (NOTAM Notice to Airmen) to check for restrictions or warnings. Record your search in your flight log. Many farm tracts are near airports and military operations areas. Apply for flight restriction clearances in advance where you have good data signals.

Update your drone, device (cell phone or iPad), and controller per the manufacturer's instructions to prevent flight delays at the field.

Properly connect the correct flight controller for each aircraft, if you have multiple drones, as mixing them up is easy. Mark each aircraft and controller, and I advise having each controller and drone under different emails for account login.

Check the overall condition of the drone, including the propellers, and make sure they are properly secured and free of damage. The body should be without cracks, and batteries should be fully charged and bulge-free.

Clean the camera lens according to the manufacturer's instructions. Use a micro-SD card with the U3 designation only.

Complete the necessary calibrations per your manufacturer. Two critical calibrations, IMU (inertial measurement unit) and Compass, are needed when flying from a different location than the original calibration. These calibrations only take a few minutes to complete, and they will keep your drone safely in the air and provide for flight accuracy.

Test your drone near the office in a safe place. Do not take off near trees, power lines, and buildings on the first flight of the year, as you may be “rusty.”

Make sure your mapping software is up to date, and if you are going to do a map, it can be easier to set up the flight plan at the office.

Plan your missions so that you have enough time, as drones can have potential problems. Assume some of those problems will occur, so budget time for that. Plan so that you, as the pilot in command (PIC), do not become stressed out over delays. Stress causes mistakes, which lead to further delays and are costly. If flight control problems arise (and they will eventually), reacting to them calmly will be easier if you start with a calm mindset.

At the Field

Viewing a field from the air can tell the farmer much about what is going on by seeing things you can't see from the road or walking in a field. August is a good month to do this, as many problems in the field manifest themselves. As time permits, flights periodically through the growing season are valuable. Here are suggestions to consider when on-site:

The use of drones for aerial field assessment allows farmers to quickly identify areas needing attention, optimizing resource allocation and saving valuable time.

Record the weather, locations, challenges, and other details in your flight log. Use your weather app to record wind speed and gusts, cloud coverage, and cloud ceilings, and check for flight restrictions that might come up in advance at the office. If you have an accident, proving you acted responsibly is essential.

Determine if you need to avoid obstacles on your flight controller. Drone obstacle avoidance features are perfect for safety. However, some drones have been known to avoid a huge orange ball in the sky known as the sun, which can disrupt your flight.

Check for other aircraft, such as aerial sprayers, drones, and machinery in the field or nearby fields. Military operations areas exist in Illinois and so be aware. As a drone pilot, you may need to receive permission to fly above fields located in these areas.

Tell others in the immediate vicinity that you must concentrate on the flight. Keep your drone flights within sight.

Check your emotional intelligence. Be calm before takeoff and during any problems. Know your limits, and do not try to do too much. When you are more engaged emotionally, returning to do the flight later may be the best decision.
Do a short test flight. Be sure to record flight data from each flight.

Mapping takes time, and drone battery life is limited. Scout fields first by looking through your screen and by taking general photos or videos. This is much quicker and more efficient. You can always go lower to view potential problem areas. Make notes on the location of problem areas, and then review your notes and photos/video back at the office.

Once back at the office, decide whether to do a full field map with the proper software or whether another inspection of specific locations is necessary. Some drone models can be used to set up the RTK (Real-Time Kinematic) systems you use on your tractor or combine.

Windy conditions in farm fields occur often as wind speeds approach 20 mph, practice in open areas, and know your drone's capabilities.

There are many other considerations when making your first scout flight of the year or even other flights as the growing season progresses. As drone pilots, getting complacent and skipping over essential details is easy. Problems and collisions can and do occur, but careful planning helps to avoid these situations. The PIC assumes full responsibility for mishaps. Heavy fines and prison sentences are real consequences for deliberate or unplanned mistakes. If you are fully prepared for your flight, field scouting with drones can be very beneficial to your farm operation.
