A 63 year old male passenger said he was unwell and rang the call bell to find the steward for assistance.

In order to get a better treatment environment for passengers, the Steward will transfer the passengers to business class and lie down together with the consent of the doctor. The doctor took the passenger's blood pressure through the on-board first-aid kit to carry out the rescue operation. Due to the passengers' unstable physical condition, based on the principle of life first, the crew decided to alternate to Tokyo Narita Airport with better medical conditions. As the aircraft carrying more oil on international flights and heavier itself, in order to ensure safe landing, the crew implemented the oil discharge procedure, discharged 45 tons of oil in the air, and informed Narita Airport in Tokyo to prepare for treatment.

After receiving the notice of alternate landing, China Eastern Narita ground service immediately requested the local airport for first aid and airport three customs clearance to prepare.

According to China Eastern Airlines, generally speaking, only in case of emergencies affecting flight safety or passenger life safety, the crew will take special measures such as' oil discharge '. Each airline has oil discharge procedures, which is an international common practice and in line with the general rules of international civil aviation. In this incident, the captain visited the sick passengers for many times and made the decision to drain the oil under the principle of life first.

Where's the oil from the air?

According to the controller's instructions, the flight will discharge oil at the specified altitude and area. Because the temperature and pressure at that altitude are very low, the oil will atomize as soon as it is discharged. After atomization, the oil exists in the middle of the atmosphere, which greatly reduces the degree of pollution and has little impact on residents. At present, there are special oil discharge areas near most airports. Once there is a demand for oil drainage, the controller will command the aircraft to avoid cities, airports, forests and low altitude, and enter the special airport oil drainage area for oil drainage.

Will oil drainage affect the environment? Need EPA approval?

China Eastern Airlines said that the oil discharge of the aircraft in the air is not random, but should be carried out under the command of the control and in accordance with standard procedures. Of course, once there is an air fuel discharge, the control and command will also give more convenience and attention. Aircraft oil discharge will inevitably have an impact on the environment, but any human activity will have a certain impact on the environment. With the development of civil aviation technology, the civil aviation industry and aircraft manufacturers have taken a variety of measures to minimize the negative impact of aircraft oil discharge in the air.

China Eastern Airlines said that for airlines, each air fuel discharge means an increase in cost. In fact, airlines need to pay not only fuel costs, but also labor, time and other additional costs. But fuel is valuable, life is priceless.
