Before a spray drone ever lifts off, the operator makes seven decisions in a row: draw the field boundary, classify crops and no-spray zones, pick aircraft and terrain settings, set safety buffers, inspect the generated route, adjust it and recheck coverage, then work out refills and timing. Every one has to be right: every field, every day, from scratch. None of them is hard on its own. There are just a lot of them, they depend on each other, and there is no margin. One buffer set wrong can cost an aircraft. The bottleneck is not the flight. It is the twenty minutes before it.
