Modelled flight time by conditions
Physics-based estimates from the same engine as our flight-time calculator, at 50% humidity over flat, open terrain. No pilot safety margin is applied — manufacturer data is the baseline, derated for each condition. The model is explained in our methodology.
| Wind | 0°C | 20°C | 35°C |
|---|---|---|---|
| Calm | 357 min | 385 min | 358 min |
| 10 mph | 347 min | 370 min | 347 min |
| 20 mph | 313 min | 319 min | 313 min |
| 30 mph | 300 min | 300 min | 300 min |
| Altitude (MSL) | Modelled flight time |
|---|---|
| 0 ft | 370 min |
| 2,000 ft | 363 min |
| 5,000 ft | 350 min |
| 10,000 ft | 329 min |
* Beyond a manufacturer's rated limit (wind, altitude) or outside the operating temperature range — shown for planning honesty, not as an endorsed operating condition. Beyond the wind rating the manufacturer's extreme-case time is shown; the model is not calibrated past that envelope. Altitude scenarios assume a sea-level launch site, where altitude MSL and AGL are equivalent; manufacturer altitude ceilings are quoted MSL. Estimates are modelled, not measured; always plan with a personal safety margin.

Tools and guides that pair with this drone's specifications
Long ISR sorties cross changing air masses, and humid air is thinner air. See how humidity affects drone performance before planning endurance at the edge of the DT46's operating envelope.
With an 8,000 m service ceiling, the DT46 routinely flies where thin air cuts lift and endurance. The altitude adjustment guide covers the density-altitude corrections to apply up there.
Enterprise operations live or die on pre-flight discipline. Run the FAA pre-flight checklist before every launch.
