Drone Flight Time Calculator

Drone Flight Time Calculator — Advanced

Technical estimates using battery Wh, voltage sag, C-rate, payload, altitude & temperature effects. Client-side only — no saving or export features.

Battery & Power

Battery capacity (mAh) Battery nominal voltage (V) Battery internal resistance (mΩ) Battery max continuous discharge (C) Number of cells (S)

Drone & Propulsion

Takeoff weight (including battery & payload) (kg) Payload weight (kg) Total prop disk area per prop (cm²) For single-prop disk area. Multiply by prop count. Example: 14"×4.7" roughly 78 cm² disk area per prop (approx). Number of props / motors Motor+ESC propulsive efficiency (0-1)

Environment & Flight

Altitude (m) Ambient temperature (°C) Wind (m/s) (positive = headwind) Flight profile Safety reserve (%) (energy saved for landing)

Flight SOC vs Time (minutes)

Model summary: Uses battery energy (Wh), estimated hover power from total thrust & disk area, adjusted by propulsive efficiency. Accounts for altitude/temperature density, battery internal resistance sag, and C-rate limits.
