Two gallons per acre is a commonly labeled carrier volume for many aerial applied products. At that volume, 18 acres per hour is realistically achievable. At 1 gallon per acre, the efficiency increases to 26 acres per hour. The application efficiency depends upon several factors, liquid rate per acre, field shape and size, field accessibility, and setup for refill. Simply put, the more acres sprayed per tank refill, the more acres per hour you will cover. The Agras T16 has a 4 gallon tank so 2 acres per refill is what you can expect spraying 2 gallons per acre at maximum efficiency. A fast refill time and short distance from refill area to spray point is crucial to achieving maximum efficiency. Once landed, the Agras T16 can be refilled, have battery replacement, and take off in less than one minute, the fastest of all sprayer drones. The home/refill point can be moved to stay close to each pass, therefore increasing efficiency.
