Under the premise of not affecting the safety and comfort, in order to "slim down" the aircraft, airlines began to work hard on the interior of the aircraft. Traditional airplane seats are very heavy. After technical improvement, thin seats were born after 2009. At the 20 12 Hamburg Air Show, many airlines including Shandong Airlines paid attention to thin seats, and Lufthansa and other airlines have already used thin seats. Shandong Airlines cooperated with Germany Ruikaiwei Aircraft Seat Co., Ltd. to install lightweight seats for 25 newly introduced aircraft. The weight of a single seat is 1 1.5 kg. 168 seats are all modified, and an aircraft can lose 80.4 kg. Don't underestimate this figure, it is only equivalent to the weight of an adult man. Save an average of 224 tons of fuel every year. Based on a ton of 6400 yuan, the annual cost can be saved by 654.38+04300 yuan, and the carbon emission can be reduced by 707 tons.

The thin seat increases the space without reducing the comfort, and the designer designs the magazine bag on the upper part of the seat back to release the lower space. This light and thin seat not only reduces the weight and saves fuel, but also improves the comfort of the seat. As a captain, he often applies for temporary routes, which can shorten the flight time, save costs and reduce carbon dioxide emissions. On one occasion, Zhengzhou flew to Jinan via wei county. Gao Yujie applied for a temporary route. After coordination and approval, the route was adjusted to Zhengzhou to Jining and finally to Jinan, and the flight distance was shortened by 87 kilometers. According to the calculation of flying 20 times a month, it can shorten the flight distance 1740 km, save 6 tons of fuel and reduce carbon emissions 19 tons. In the first half of 20 14, Shandong Airlines pilots saved 6,576 tons of fuel and reduced carbon emissions by 20,780 tons.

Applying for temporary routes is the most direct way to save fuel. Just like a car, the oil saved by "driving in a straight line without detours" is the most real. Pilots cannot apply for temporary routes without dispatchers. Shandong Airlines has regulations on assessment of energy conservation and emission reduction, and dispatchers should be assessed every quarter.

After analyzing the weather, routes, airports and other factors, dispatchers can contact the air traffic control department and apply for temporary direct flights. August, 2065438 14, Shandong Airlines flight SC4934 (Wuhan-Jinan) was released. After analyzing the weather, routes and other factors, Ray applied to Jinan Air Traffic Control for a temporary route (Zhoukou-Jining-Jinan), which was allowed. After the plane landed, Ray explained the direction of the temporary route to the crew. The flight successfully implemented the temporary route, shortened the route 140 km, saved the flight time 15 minutes, and saved about 400 kg of fuel.

Shandong Airlines has 182 temporary routes to apply for. In the first half of this year, only one route optimization will save fuel 17 13 tons and reduce carbon emissions by 54 13 tons. The reporter learned that the transportation control center has developed computer flight plan accuracy monitoring, comparing the actual flight route and fuel consumption of each month with the designated flight plan, and making timely adjustments for different change gaps. Liu Xiaolian told reporters that in the transportation control center, the refueling error of each dispatcher's flight plan should not exceed 200kg. Don't underestimate this 200 kg, the dispatcher can accurately calculate the minimum fuel quantity required for aircraft flight and master the accurate fuel quantity on the premise of fully ensuring flight safety. This alone can save about 400 tons of fuel consumption and reduce about 1.300 tons of carbon emissions for Shandong Airlines every year. In a prominent position in the office hall of the operation control center, there is a honor roll, which reads the energy-saving star of each quarter. When the plane is not flying on the ground, it also has great "saving" potential. It has become a general trend for many airlines and airports to use ground-powered vehicles instead of aircraft APU to save fuel consumption.

APU is equivalent to a small engine, located at the tail of the plane, which is responsible for providing power when the plane is parked on the ground. Liu Xiaolian told reporters that the first flight of the day is at 8: 30, and the preparations will start at 6: 00. In the preparation stage, all kinds of equipment, such as lighting, air conditioning, maintenance, etc., will be turned on, which all require energy consumption. In the past, airlines used APU to provide energy by consuming jet fuel, which was expensive. Nowadays, more and more airlines are "smart" and use ground powered cars or covered bridges to solve the energy consumption problem before the plane takes off, which greatly reduces the cost.

Take the ground-powered vehicle as an example. Shandong Airlines has more than 20 ground powered vehicles in Jinan, Qingdao, Yantai and Xiamen. Compared with aircraft burning oil, the fuel consumption of ground-powered vehicles is very small. In the case of using APU to power the aircraft, the hourly cost is close to that of 900 yuan, and even without air conditioning, it is close to that of 800 yuan. The hourly cost of using a ground-powered car is about 250 yuan. Foreign ground power supply vehicles are converted into commercial power, which greatly reduces the consumption of ground power supply vehicles and turns "gasoline" power supply into "commercial power".

The covered bridge power supply is connected to the aircraft through the covered bridge to provide energy, which is farther than the ground power supply vehicle. The power supply of the covered bridge directly uses the city power to supply power to the aircraft, which is a real "power supply by electricity". The reporter learned that the hourly cost of using covered bridges for power supply is less than that of 200 yuan. Power supply for covered bridges requires airport facilities. At present, the power supply of non-distant seats in major airports in China has been provided by covered bridges, but the covered bridges in some airports cannot provide air-conditioning facilities.

Every once in a while, the crew will "bathe" the plane parked on the ground to reduce the weight of the plane by cleaning its appearance. There are even some freighters abroad who have removed the external paint of the aircraft in order to reduce the weight of the fuselage. Liu Xiaolian told reporters that if the plane's appearance is not smooth enough, it will be affected by aerodynamics to increase the resistance, and the dust formed on the surface will increase the weight of the plane. With the increase of flight time, the aircraft will become heavier and heavier. The aircraft of Shandong Airlines will be weighed during regular inspection and the appearance of the aircraft will be cleaned regularly.

In addition to cleaning the appearance of the aircraft, the engine of the aircraft also needs to be cleaned regularly. With the increase of engine service time, engine fuel consumption will also increase, just like a car, engine fuel consumption will also increase after a long time. Therefore, the crew will regularly clean the aircraft engine according to the number of engine cycles. But the biggest source of carbon emissions in the aviation industry is aviation fuel. Aircraft not only emit a lot of traditional pollutants such as nitrogen oxides, but also emit greenhouse gases including carbon dioxide and water vapor. The data shows that the carbon dioxide emissions of aviation fuel account for 90% of the total emissions of the entire aviation industry. With the development of international civil aviation, bio-aviation fuel was born. Bio-aviation fuel extracted from gutter oil has sufficient power during flight, which is no different from using traditional aviation fuel, and can reduce the overall carbon intensity of the fuel used. Compared with traditional jet fuel, bio-jet fuel can reduce carbon dioxide emissions by 55% to 92%, which is not only renewable and sustainable, but also does not need to modify the engine. It has a high environmental protection advantage and has been used all over the world.

United States:

On June 7, 2009, a Boeing 737 of Continental Airlines successfully completed the first commercial aircraft biofuel test flight in North America.

Netherlands:

20 1 1 On June 29th, 2008, KLM used waste cooking oil ("gutter oil") as the raw material of its biofuel, and carried 17 1 passengers from Amsterdam Airport Schiphol in the Netherlands to Paris Charles de Gaulle Airport. KLM became the first airline in the world to use biofuels on commercial flights.

Germany:

On 20th11July15th, an Airbus A32 1 of Lufthansa began to use biofuels. As one of the first experiencers of "green flight", this passenger plane flies back and forth between Hamburg and Frankfurt four times a day. One of the two engines of the passenger plane will use mixed fuel, that is, 50% conventional fuel and 50% biofuel.

Britain:

20111kloc-0/On October 7th, Thompson Airlines successfully launched the first "gutter oil flight" from the British airport. This flight, which set a new record in space history, belongs to Thompson Airlines, carrying 232 passengers, and flew from Birmingham, England to sallot, Spain. 50% of "hydrogen esters and fatty acids" are added to the fuel of one engine of a twin-engine Boeing 757, which is processed from kitchen waste oil, also known as "gutter oil".
