Wind shear hazard investigations, flight simulation for pilot training as well as design, development, and testing of flight control systems require suitable wind models. Based on flight test data, airline flight data and meteorological tower measurements, engineering models for dangerous wind shear situations were developed in the frame of different wind shear research projects. Derived from simplified fluid dynamic concepts the engineering models for downburst, frontal wind shear, and low level jet meet the requirements for real-time flight simulation. The comparison of the wind models with measured wind data show good accordance. For the analyses of simulated landing approaches in wind shear conditions a hazard definition is given by means of aircraft energy height deficit, respectively the required energy supply for landing approach on nominal glide slope and constant air speed.
