The article considers the influence of the atmospheric boundary layer, which is located directly at the earth’s surface, to determine the location, relative to the glide path planning, the aircraft performing a visual approach. Taking into account the physical properties of the atmosphere and complex spatio-temporal changes in the refractive index of the atmosphere, was obtained mathematical model allows to calculate the errors in determining the position of the aircraft relative to the glide path planning. The basis of the mathematical model is based on the law of refraction. With the passage of the interface of adjacent layers with different refractive indices, a deviation of the trajectory observations of the runway from the straight. When performing a visual approach the aircraft can be located both below and above the glide path planning. This leads to an undershoot or an aircraft’s flight zone of contact with the runway. Initial data for calculation of the range of possible errors in the determination of the random position of the aircraft relative to the glide path planning, are details about the actual state of the meteorological elements and the height of the aircraft approach for landing.
