Most of airports in China are not located in plain, the surrounding topography is complex, and with the construction of infrastructure, the artificial barriers around the airports are increased, so that aviation safety can be threatened.
In order to ensure aviation safety, the obstacles at the periphery of an airport are managed, the visibility of the obstacles at the periphery of the airport is improved, and the obstacles are often marked in a mode of installing and marking visual navigation aid facilities for the obstacles so as to improve the safe operation level of the airport.
Along with the development of economy and the improvement of productivity, the demands of industry and life on electric power are also increasing day by day, and the construction of high-voltage line engineering is also improved day by day.

Therefore, it is highly desirable to provide a method for installing obstacle lights on a tower according to the actual flight path of a flight.

finally, the sum of the width between the two side basic boundary tracks, the horizontal positioning error of the position receiving equipment and the span length of the 1/2 aircraft is taken as a 'horizontal track area'. The horizontal track area can be used for carrying out the lamp loading analysis of the tower pole obstacle. The GNSS position receiving device of the ADS-B has certain horizontal positioning error and certain width of the wing span of the aircraft, so that the sum of the width between two side basic boundary tracks, the horizontal positioning error of the position receiving device and the length of the wing span of the 1/2 aircraft is taken as a horizontal track area, and the horizontal track area is an essential path of the aircraft in the airspace.

By carrying out real calculation on the high-voltage line tower pole and the flight path of the aircraft, the accuracy of the invention in the actual operation process is ensured, and the installation scheme in the prior art is kept for the tower pole barrier in the airport barrier limiting surface, so that the tower pole in the airport-near zone can be clearly found, and the navigation safety can be ensured.
