Frequently asked questions
Verifying Williams Drones runs through three independent checks: Part 107 via the FAA Airmen Inquiry, Part 137 via the issuing FAA Flight Standards office, and the state aerial-category pesticide applicator license via the receiving state's department of agriculture. In South Dakota the state credential is issued by South Dakota DANR; you can ask the operator for the applicator license number and verify it with the agency directly. Pair that with a current chemical-drift COI and the Section 44807 exemption number for due diligence.
Typical drone spraying rates of $12 to $25 per acre in the region usually breaks down into three lines: (1) included — calibration, GPS-guided flight planning, machine and pilot labor to fly the field, mixing and loading farmer-supplied product, and a Part 170-compliant application record; (2) excluded — the pesticide and any adjuvants, which the farmer supplies; (3) surcharges — long travel, after-hours, difficult terrain or obstruction-heavy fields, and minimum-acreage charges below a stated threshold. Spell out which of those land on your invoice before the operator schedules.
