Civil Aviation Resource Network August 21, 2022 News: An Ethiopian Airlines flight on Monday missed the landing time because two pilots fell asleep during the flight, and did not wake up until the passenger plane alarm sounded. Fortunately, it finally landed safely. The incident was suspected to be related to pilot fatigue, and both pilots were suspended pending investigation.
The Ethiopian Airlines Boeing 737-800 was flying from Khartoum, the capital of Sudan, to Addis Ababa, the capital of Ethiopia, but when it was supposed to start its descent, the plane continued to fly at a cruising altitude of 37,000 feet.
The personnel of the air traffic control tower contacted the two pilots several times to no avail. The passenger plane continued to fly and even flew over the runway. After that, the autopilot system disengaged and issued an alarm. The two sleeping pilots woke up and the passenger plane landed safely 25 minutes later.
Ethiopian Airlines said in a statement that it received reports that the flight number ET343 lost contact with the air traffic control tower personnel during the flight on Monday, and the two pilots have been suspended.
Why did the pilot fall asleep? According to senior captain Chen Jianguo, first of all, this kind of thing is not the only one, it happens occasionally every year. This problem is definitely the pilot's problem, but to avoid this serious problem from the source, it is still necessary to comprehensively understand the problem.
The pilots fell asleep at the same time, most of which were caused by the pilots being too fatigued, so the deep-seated problems should be solved from the aspect of fatigue management to avoid this dangerous situation from happening again.
The technical means to prevent the pilots from falling asleep. On long-range aircraft such as 747, there is a warning system to prevent the pilot from falling asleep at the same time. The system is set so that if the pilot does not press any button or input any information within 30 minutes or a preset time, the aircraft monitoring system will An audible warning will sound when both pilots are thought to be asleep.
