Route Optimization - The drone flys in a circular pattern to complete passes. For example, if you park in the middle of a 80 acre field, the drone will start in front of you directly then turn to the right, completing passes to the right of you. After that tank is complete, landed and refilled it will then start left of the trailer, complete a full pass then fly to the passes to the right of the trailer, and leave off where it left off. We noticed this morning 50% of the time it was ferrying to a short pass to fill in, sometimes a half mile away even though there are full passes right next to the drone. It is simply a battery drainer and cannot complete all liquid in the tank, because it is flying with 30gal in the tank a half of mile, at operational speeds, sometimes not being 40 mph.
