Maximum Speed Assessment

The maximum speed of your UAS is a critical parameter that directly affects the safety of the platform and consequently influences its certification category.

Speed measurements are conducted during level flight at full throttle, performed in both directions—against and with the tailwind. Note that the tailwind speed must not exceed level 3 on the Beaufort scale to ensure consistent and fair testing conditions.

To obtain accurate readings, calibrated speed measurement devices such as speed radars or laser speed meters are employed. A test setup consisting of three sensor-equipped gates is arranged in a straight line, spaced 20 meters apart. The drone operator is required to fly the UAS through these gates at maximum speed.

For each direction, three separate measurements are taken within a ±30-degree angle relative to the wind direction ( headwind and tailwind). The maximum recorded speed among all runs will be considered the official maximum speed of the UAS for certification purposes.
