Estimation of the hazard of aircraft flight in conditions of shears, of a three-dimensional wind

The justification of an efficient method for estimating the dangerous influence of three-dimensional wind shears on the flight of an aircraft is presented. The method is based on the computation of the forecast values of increments of the main pilotage parameters caused by the action of the wind and the controls compensating for these wind disturbances. The increments are found as the partial solutions of the differential equations of the aerodynamic forces and moments depending only on wind disturbances and compensating controls. To implement this algorithm onboard an aircraft, it is sufficient to use the measurements from the standard onboard pilotage equipment of an aircraft. The mathematical model with the use of the model of heavy transport aircraft has proved the workability of the method and the algorithm.
