Weather equipment installed at Beijing airport

The installation of site equipment for the automatic weather observation system for the first and second runways of the Beijing Capital International Airport began on May 26. The installation work was to be finished on June 25. That included the integration of the observation equipment of the airport’s third runway that would pave the way for a new automatic weather observation system. After a trial operation for one month,the system will officially be put into operation by August 1. The automatic weather observation system is considered an integral part of the weather center, providing aviation weather service support. The system consists of main detection units such as an RVR transmissometer, anemometer and wind vane, ceilometer, weather phenomenon apparatus, and temperature/air pressure/humidity detector. A Weather Observation Room controls them, and provides real-time ground weather detection data to control departments, airlines and related departments of the airport by computer. The system is one of the most important systems of the airport to support flight safety. The new observation system, MIDAS IV, is imported from Finland to replace the MIDAS 600 model, which has been in operation for 12 years. The new system performs better than the existing system, providing precise and effective weather data.
