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 | 1135 min | 1191 min | 1136 min |
| 10 mph | 1117 min | 1164 min | 1118 min |
| 20 mph | 1055 min | 1072 min | 1055 min |
| 30 mph | 1020 min | 1020 min | 1020 min |
| Altitude (MSL) | Modelled flight time |
|---|---|
| 0 ft | 1164 min |
| 2,000 ft | 1150 min |
| 5,000 ft | 1123 min |
| 10,000 ft | 1079 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.
