Underestimating battery requirements is one of the most common field planning mistakes on drone surveys, leading to incomplete coverage on day one and an unplanned second mobilization. This calculator estimates sorties and batteries needed based on area, flight altitude, and typical battery endurance, so you can plan logistics before the team drives to site.

Why We Always Plan With a Buffer
This calculator's default 18-minute usable flight time already assumes a buffer below the manufacturer-rated maximum, because real flights include wind resistance, payload weight, and a mandatory reserve for safe landing. Planning to the absolute rated maximum battery life is how missions run out of power mid-grid on a real drone survey.
| Site Condition | Recommended Usable Flight Time |
|---|---|
| Calm conditions, low altitude | 80-85% of rated battery life |
| Moderate wind or higher altitude | 70-75% of rated battery life |
| High altitude sites, cold conditions | 60-65% of rated battery life |
Why This Matters for Field Scheduling
Knowing battery count in advance determines whether the field team needs a generator for charging on remote sites, or whether the survey area needs to be split across multiple days. For mega aerial surveys spanning hundreds of hectares, this calculation directly drives how many drone units and charging stations get mobilized to site.
