Cross wind
As a side wind is called the wind , sideways on vehicles acting. For certain vehicles, intervention by the driver may be required to maintain the direction of travel. The crosswind stability results from the vehicle structure, aerodynamics and center of gravity .
Cross winds can lead to dangerous situations in road traffic. For example, when overtaking a truck , a car can be surprised by a sudden cross wind (when leaving the slipstream ) and lose control of its vehicle. Even light trucks (12 t articulated truck with single-axle rigid drawbar trailer) can tip over at full speed from a crosswind force of 7 Beaufort . Even with takeoffs and landings of airplanes , a side wind is ( English crosswinds ) extremely risky from a certain intensity and direction, see side wind landing . Cross winds (and also winds from other directions) also influence the flight of missiles and cause a need for control when aiming at a target.
