Calculators

Field math for spray-drone operators.

These tools are intentionally narrow. They do not replace label instructions, calibration, or state pesticide rules; they help you sanity-check productivity before buying equipment, hiring a service, or quoting a custom spray job.

Field math console

Use the calculators in the order a spray day fails.

First estimate the pass-rate ceiling, then check whether the tank makes refills the bottleneck, then test whether the battery lane can keep the aircraft moving.

Pass rate

Can the aircraft cover enough acres per hour?

Tank cadence

How often does the crew refill?

Battery lane

Does charging keep pace with sorties?

29.5 ac/hr

Sample output

Spray acres per hour

Swath x speed adjusted for overlap and field efficiency.

Assumes: 30 ft swath · 12 mph · 75% field efficiency

Use this when: Use when a dealer, service quote, or field plan gives you swath and speed.

Swath and efficiency move this number fastest.

4.8 ac/fill

Sample output

Spray tank coverage

Usable gallons divided by gallons per acre.

Assumes: 10.6 usable gal · 2.2 GPA application rate

Use this when: Use when label rate or carrier volume may turn the job into a refill problem.

Carrier volume changes refill cadence immediately.

150 ac/day

Sample output

Battery swap productivity

Flights per day multiplied by acres per flight.

Assumes: 12 flights · 12.5 ac/flight · clean swap lane

Use this when: Use when the aircraft looks capable but the battery lane may not keep up.

Swap time and charge capacity decide whether sorties stack.
