Air india saves money by recruiting slim stewardesses, which can save $500,000 a year. In order to save gas money, flight attendants recruited by an Indian airline named GoAir are mainly slim women. The average weight of slim stewardesses is lighter than that of men 15-20kg. The company calculated that it would cost 0.05 cents per hour for every kilogram of weight added in air flight. The new recruitment standard is expected to save 500 thousand dollars every year.
In order to reduce carbon dioxide emissions, ANA requires passengers to "pee" in the toilet before boarding the plane. All Nippon Airways said that if the passenger's bladder is "empty", it will reduce the weight of the aircraft during the flight, thus reducing the fuel consumption. ANA staff will ask passengers to "conveniently" go to the toilet to lose weight before boarding the plane. The company hopes that the "saved" weight can reduce 5 tons of carbon dioxide emissions within 1 month.
Air France reduced the weight of plastic water cups on the plane to reduce fuel consumption. Under the condition of ensuring flight safety, Air France tries to reduce the weight of aircraft and avoid unnecessary fuel consumption, so as to reduce carbon dioxide emissions. For example, the weight of the small plastic cups used by passengers in the cabin to drink champagne, cola and other drinks has been reduced from 13 grams to 9.5 grams. This small "slimming" of 3.5 grams can reduce 20 tons of carbon dioxide emissions a year after it is extended to all flights of Air France.
Air Canada uses iPad to lose weight in the cockpit. Air Canada uses iPad instead of paper manual in the cockpit. Although it doesn't sound new, it works well. Each pilot's paper manual weighs about 35 pounds, which means that the long-distance route of the two units will increase by more than 100 pounds. Using iPad instead of paper manual can not only reduce the weight of aircraft and fuel consumption, but also update the content regularly to improve efficiency.
The Air in JAZZ, Canada is equipped with buoyancy equipment instead of life jackets to reduce the weight of the aircraft. Canada's Ministry of Transport, Infrastructure and Community stipulates that if a passenger plane flies within 50 nautical miles (92.6 kilometers) from the coastline, airlines can equip the cabin with buoyancy devices instead of life jackets. At present, JAZZ uses cabin cushions as buoyancy devices. A commercial life jacket weighs about 0.5 kg. JAZZ's passenger plane carries 50 passengers, and the total weight of life jackets equipped on board is about 25 kilograms.
British Airways has taken various weight-loss measures to reduce operating costs. British Airways staff are required to pay attention to personal weight, reduce the packaging of airplane meals, reduce the supply of iced drinks on board, reduce the size of knives and forks, use lighter tableware, replace bulky dining cars, and cancel sugar bags and headphones. At the same time, it also reduces the size of the airborne magazine to reduce the total weight of the aircraft and reduce the operating cost. Ryanair's in-flight magazine "Walking with Ryanair" has reduced the paper size from A4 to A5, and the bottom is used as a menu. Virgin Atlantic's method is to reduce the packaging of food, such as bread is no longer wrapped with plastic wrap, and finally achieve the goal of unpackaged food. In addition, Virgin has introduced lighter seats and trash cans, which can reduce the weight of thousands of tons per plane every year.
American airlines set up an energy-saving and consumption-reducing team to deal with rising fuel prices. In 2005, American Airlines, headquartered in Fort Worth, Texas, set up a special energy-saving and consumption-reducing team to "cheat" in places where passengers are not easy to detect and reduce the load of aircraft. For example, the team "removed" the socket and power converter in the bathroom of the aircraft cabin, and removed the telephone behind the aircraft seat and the telephone line buried in the seat. In 2007, silver tableware used in business class and first class was replaced by lighter tableware. Through weight reduction measures, the company estimates that it can save about 420 million liters of fuel every year.
Spring Airlines has refined hundreds of fuel-saving measures to "slim down" the aircraft. In 2009, when the financial crisis spread, the net profit of Spring Airlines was 654.38+58 billion yuan, an increase of 524% over the previous year. One of the secrets of rising profits is to reduce costs. Hundreds of fuel-saving measures were refined in spring and autumn. In addition to optimizing routes and aircraft altitude and speed, most airlines also save fuel by "slimming" aircraft. General airlines carry full water, but they need to carry water according to the line demand in spring and autumn, and many flights only carry one third; Generally, there is a dining car on the plane, but it will disappear on the plane in spring and autumn to reduce the weight of the plane.
Improve and upgrade the structure of in-vehicle entertainment equipment to reduce the weight of the equipment. As one of the major manufacturers of in-flight entertainment equipment, the newly launched eXLite products of Matsushita Corporation of Japan come from XSeries series. Its advantage is mainly the improvement of the structure, which only needs to be upgraded on the basis of the original equipment and remove redundant components. This not only avoids a lot of disassembly work, but also reduces the weight of the upgraded equipment by 30%. Similarly, TopSeries, an in-flight entertainment equipment produced by French company Treize, is suitable for 70-seat Bombardier CRJ aircraft and 550-seat Airbus A380 aircraft, with an average weight loss of about 3.8 pounds each.
The high-performance carbon/carbon brake disc developed by AVIC Brake Company can reduce the weight of aircraft brake device by 30%. These carbon/carbon brake discs will soon be applied to China civil aviation A320 aircraft. It is understood that the high-performance carbon/carbon brake disc developed by AVIC brake can reduce the weight of aircraft brake device by about 30%, which is undoubtedly a revolution for aviation manufacturing. Carbon/carbon composite brake materials have been widely used in military aircraft and civil aircraft in developed countries.
