How to use this calculator
- Enter the flight speed, swath (line spacing) and flight time per battery.
- Press Calculate.
- Read the coverage rate and area per battery.
How it works
Coverage rate = speed × swath width; area per battery = coverage rate × flight time. It ignores turns and overlap, so treat it as an upper bound.
Worked example
8 m/s, 70 m swath, 18 min. About 60 ha per battery (before turn/overlap losses).
Frequently asked questions
Why is real coverage lower?
Turns at the end of each line, image overlap and acceleration all reduce effective coverage — budget 20–40% less.
