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.

* 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.
