Safe Max Wind Speed81 km/h
Safe Max Wind Speed50 mph
Thrust-to-Weight Ratio2:1
Beaufort Scale Limit8
How to Use This Calculator
  1. Enter your drone's all-up weight (grams) including battery and payload.
  2. Set maximum thrust per motor (grams-force) and total motor count.
  3. Enter a gust factor (1.0–1.5) to account for turbulence above the steady-state wind speed.
  4. Review safe maximum wind speed (m/s, km/h, and mph) and corresponding Beaufort scale level.
  5. Never operate at the safe limit — use 70% of the calculated value as a practical operational limit.

What each input means

Drone All-Up Weight
Total weight including battery and payload.
Max Thrust per Motor
Maximum thrust output per motor at full throttle.
Number of Motors
Number of motors on the aircraft.
Gust Factor
Safety multiplier for gusts (1.5 = gusts 50% above average wind).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Drone All-Up Weight = 3000, Max Thrust per Motor = 1500, Number of Motors = 4, Gust Factor = 1.5 = 4 input(s) provided
  2. Calculate Safe Max Wind Speed
    Safe Max Wind Speed
    22.5 = 22.5
  3. Calculate Safe Max Wind Speed
    Safe Max Wind Speed
    81 = 81
  4. Calculate Safe Max Wind Speed
    Safe Max Wind Speed
    50 = 50
