Whether a
drone can complete a task safely and smoothly depends on the weather and the environment. Needless to say, rain and snow, basically can not perform the task, then in the case of sunny weather with windy, we know that the wind is divided into 0-12, under what kind of wind, the drone can be executed normally task.
In general, wind is the amount of power that the wind exerts on an object. However, according to the various phenomena generated by the wind blowing on the ground or the surface of the water, the size of the wind is divided into 13 levels, the minimum is 0 (no wind), and the maximum is 12. The winds appearing on land are generally between 0-9, and the winds of 10-12 are rare on the land. Some trees are pulled down and buildings are destroyed. The destructive power is extremely great.
Light aircraft: helicopters, power delta wings, fixed wings and other general wind resistance are around 5 (about 9 meters); hot air balloons, powered parachutes, paragliders are safer than the 4th wind (6 meters) than flying. The wind is converted into the corresponding wind speed: that is, the distance the air flows in a unit of time, expressed in meters per second. Among them, the wind speed of the first-class wind is equal to 1 m / s; the wind speed of the second-class wind is equal to 2 m / s. The wind level of the 3rd wind is increased by 1, and the wind speed is equal to 4 m/s. Levels 4 to 9 subtract 2 from the series and multiply by 3 to get the corresponding level of wind speed. The wind speed algorithm of 10 to 12 grades is: 10 wind speed is 27 m / s, on the basis of this, add 4 to 11 wind speeds of 31 m / s, plus 4 to get 12 wind speeds of 35 m / s.
The conversion is as follows for reference: two is two to one, one is three, three is one plus one. It is not difficult to calculate four to nine levels, and the number is reduced by two by three. Ten to twelve are rare, and it is easy to keep in mind the tenth level. The tenth wind speed is twenty-seven, and each additional four is more than one level.
