On May 14th, during the flight of Sichuan Airlines, the front windshield broke, and after 40 minutes of shock, Chengdu Shuangliu Airport was successfully prepared.
When everyone is crazy about "Captain Sally in China" Liu Chuanjian, the situation target seat and air traffic control seat of the air combat command and control center in the western theater are working hard as usual.
Few people know that on the morning of May 14th, it was because of these "clairvoyance" and "air traffic police" that they discovered the "7700" code, which meant the mechanical failure of the aircraft, and quickly stopped more than a dozen aircraft that had slipped onto the runway, and the airspace north of the Tibet route was deployed by civil aviation, ensuring that Sichuan Airlines 3U8633 was able to take the shortest route and make a successful backup in the least time.
Hero, Liu Chuanjian is not the only one.

Radar found Sichuan Airlines 3U8633 yaw.
Descending 2000 meters a minute
On May 14th, at 7: 08 a.m., Guan Jianke and Li Dongbo, staff officers on duty, were monitoring the air situation in and around the area of responsibility at the situation target table of the air combat command and control center in the western theater.
▲ Guan Jianke, the radar intelligence attendant, keeps a close eye on the screen and always keeps a high degree of vigilance to monitor the flight of various aircraft in the air.
Suddenly, they found that Sichuan Airlines’ flight 3U8633 from Chongqing to Lhasa suddenly changed course and deviated from the route to fly south, 122km west of Shuangliu Airport on the Sichuan-Tibet route: "In less than one minute, the flight altitude dropped rapidly from 9400 meters to 7300 meters." Guan Jianke immediately informed a brigade of the Air Force radar in the relevant airspace, transferred to the first-class duty and added radar, strengthened the monitoring of 3U8633, and paid close attention to the altitude change. At the same time, notify all the duty seats at the corresponding level for collaborative disposal.

At 7: 10: 30, radar information showed that the secondary code of Sichuan Airlines 3U8633 had changed from 2245 showing normal flight to "7700" indicating aircraft mechanical failure. Guan Jianke immediately started the abnormal air handling procedure and informed the relevant seats at the corresponding level to coordinate the handling.
More than ten military aircraft "stopped" in 5 minutes.
6 minutes to release airspace for civil aviation deployment
At 7: 11, Xin Xinmeng, the attendant who was calling to deploy military aircraft, looked up. The flashing "7700" on the screen of the air traffic control terminal of the air traffic control seat reminded him that he had been holding this position for 6 years: "Something big happened!"

The computer shows the flight number. At this time, the altitude of Sichuan Airlines 3U8633 has dropped to 7200m. Xin Xin immediately contacted the duty officer of Southwest Air Traffic Control Bureau of Civil Aviation, and learned that the front windshield of Sichuan Airlines 3U8633 was cracked and was preparing to descend to Shuangliu Airport, but the airport was unable to contact the crew: "The whole call took less than one minute, and the person who answered the phone was very anxious and spoke quickly."
This is a battle that must be won!
Xin Xin made emergency arrangements for related activities according to the possible areas involved in the emergency standby of Sichuan Airlines flight 3U8633, and quickly reported to the chief duty officer of the command post and the air traffic control duty officer to coordinate with ICAO to avoid the aircraft. About an hour ago, Xin Xin made a lot of phone calls. Every phone call was related to the reception and release of the military aircraft that day. He knew that at that time, more than 10 military aircraft had slipped into a runway of an air force aviation unit in the western theater to fly, and some training flights were about to take place. These military aircraft will fly to all directions in the southeast and northwest of China. Xin Xin immediately called the control attendant of a division of the Air Force Aviation: "All transfer planes and training planes in this field will take off at your command. Your tower frequency is consistent with Shuangliu Airport. Try to contact Sichuan Airlines 3U8633 by radio immediately. "
On the ground, more than 10 military aircraft were quietly on standby on the runway of a certain air force aviation unit in the western theater. At this point, it is 7: 16.
In the air, the air combat command and control center of the western theater released the airspace north of the Tibet route, which was used as a deployment by civil aviation flights. In this airspace, ordinary civil aircraft are forbidden. At this point, it is 7: 17.
Three-place linkage
Until 3U8633 is safely standby.
At 7: 20, Xin Xin received a report from the duty officer of Southwest Air Traffic Control Bureau of Civil Aviation, and got intermittent contact with Sichuan Airlines 3U8633. He could hear the call in the air, but he could not receive the ground notification in the air. Shuangliu Airport was ready for alternate flight.
At this time, the Southwest Air Traffic Control Bureau of Civil Aviation, a division of the Air Force Aviation in the Western Theater, and the air combat command and control center in the Western Theater are all trying their best to escort Sichuan Airlines 3U8633.
Xin Xin stared at the screen and watched the flying height of the plane drop a little: "Get closer to the ground, and my heart will fall a little." In just a few minutes, Xin Xin’ s heart turned around. "If you don’ t put oil, is it safe to land?" "How does civil aviation command landing?" "Can you land safely?"
As an air controller, he knew that the captain was at an altitude of more than 9,000 meters. If the glass cracked, it was impossible to hear the ground call: "If the cockpit loses pressure, the human body may lose consciousness at the first time. Usually we train, the cockpit above 4000 meters needs to be completely closed, and we must wear an oxygen mask. "
At 7: 25, Xin Xin once again called the Southwest Air Traffic Control Bureau of Civil Aviation, requesting a timely report on the alternate situation.
The phone suddenly rang, and Xin Xin heard the good news at the speed of seconds: "Sichuan Airlines 3U8633 successfully prepared!"
