What is the role of the Capital Airport in completing the 150m low visibility verification test flight?

Recently, the Capital Airport completed the low visibility test flight of 150m, which will improve the normal flight rate in the future.

On September 8, fog and haze were one of the bad weather factors that affected the punctuality rate of flights. In order to improve the flight support capability and flight normality of the Capital Airport, the Capital Airport successfully completed the verification test flight using the head-up display at 1 on the morning of September 8 under the condition of low visibility of the runway, with the visual range of150m. After the popularization of this technology, it is expected to improve the punctuality rate brought by visibility.

On the morning of 8th Beijing time 1, the MU700 passenger plane of China Eastern Airlines was also the first flight test of China Civil Aviation based on runway sight distance 150m, relying on airborne optical display system.

According to the statistics of the Civil Aviation Administration of China, weather accounts for 56% of the factors affecting the normal rate of flight 20 16, especially in winter and spring, and the low visibility weather represented by fog and haze accounts for a large proportion. Taking the Capital Airport as an example, the annual runway visibility is less than 200m for 44 days, 150m for 3 1 day, and 90m for 9 days. Therefore, CAAC actively promotes the new navigation technology represented by HUD head-up display to further reduce the impact of low visibility weather on the punctuality rate of flights.

In the early morning of September 8, two test flights landed smoothly under the command of North China Air Traffic Control Bureau. Shang Feng, the captain of China Eastern Airlines flight MU700, told the passengers who experienced the test flight through the on-board broadcast: "The plane has landed safely and successfully completed the verification flight of the A320 model HUD 150 at the Capital Airport. Thank you. "

This flight test verified the feasibility of taking off with HUD head-up display for runway visual range 150m of Capital Airport. According to the relevant person in charge of the Flight Standards Department of the Civil Aviation Administration of China, when the visibility is lower than 150m, the roads in expressway are closed and the speed does not exceed 20km/h, while the aircraft of airlines with HUD operation qualification can take off from the Capital Airport smoothly. Li Jian, deputy director of the Civil Aviation Administration of China, called it "a revolution in the cockpit".

Li Jian, deputy director of the Civil Aviation Administration of China, said: "During the landing, pilots usually look out first, then at the instrument, and keep switching back and forth. In the process of switching, it is easy to lose the attitude of the plane and delay some time. HUD is a head-up display instrument. You can see the runway without looking down, and all the main instrument data are displayed on the HUD, which greatly reduces the complexity of the pilot's operation. When using HUD, the pilot will feel that the accuracy will be greatly improved, and the take-off under complex weather conditions and low visibility conditions will also be improved. It used to be 400 meters visibility to take off. This time we tested150m, and it will reach 90m in the future. Even from 200 to 150, this 50 meters is a great progress. Accelerate the resolution of flight delays with new technologies and other management methods. "

In the next step, North China Regional Administration, North China Air Traffic Control Bureau, Capital Airport and airlines will continue to study the feasibility of using HUD head-up display to carry out a 90-meter take-off test flight at Capital Airport, so as to bring better flight experience to passengers.
