Description: The wind shear is one of the most dangerous phenomena in the atmosphere for aviation. The artificial shift of air masses, caused by the release of a large amount of energy in the air space, is an analog of the natural wind shear, but can be much more powerful. Artificial displacement of air masses is considered as a wind displacement of the sinusoidal type, described by the corresponding system of differential equations. The determination of the wind shear and its occurrence is made with the aid of a lidar and an inertial system, which can also be used to determine the artificial displacement of air masses. Established in the regions of the airports, the lidars measure wind shifts on the airfield, the turbulence of the airplane track and other atmospheric parameters that are known to ensure the safety of the meteorological approach to take-off and landing of aircraft. An inertial wind shear determination system is installed on board an aircraft, thus solving the tasks set in accordance with the temporary and spatial position of the aircraft. The use of the instruments considered in the kit to determine the artificial displacement of air masses would enable the crew to reduce the dangerous impact on the dynamics of the aircraft, or in general avoid it.
