Domestic airline passengers will be able to make phone calls and send e-mails from the sky from next year, a local carrier has said. Shenzhen Airlines said on Monday it has signed an agreement with Geneva-based On-Air to provide passengers with in-flight communications services on all its planes by the end of 2009. The service will be introduced on three aircraft ahead of the 2008 Olympics, on two routes----from Shenzhen to Beijing and Shenzhen to Shanghai, the airline said. Passengers will be able to use their own electronic devices to send e-mails and short messages, make calls and surf the Internet, it said. The service is expected to be of particular interest to business travelers. According to a survey at the end of last year, China had 4.55 million mobile-phone subscribers. Ninety-three percent of those polled said they wished they could send and receive e-mails and messages while on a plane. Despite the introduction of the new service, passengers will still be prevented from using their cell phones and laptops when the plane is taking off and landing, or flying at less than 3,000 m above sea level, the official said. The official said the new service would not lead to an increase in ticket prices, but users of Chinese mobile-phone services will be charged the international roaming rate for any calls made from the sky. Shenzhen Airlines is the first Chinese carrier to provide such in-flight communications services. Its president, Li Kun, said installing the facilities will cost 4.5 million yuan ($596,000) per aircraft. However, the project still needs to be approved by the Civil Aviation Administration of China, a source said.5. It can be inferred that the new service will probably cause( ).

The Boeing 747-400 airplane has reached its cruising altitude of 10,000 meters and cruising speed of 900 km per hour on its way from London to Beijing. The Purser has announced that the passengers are now free to unfasten their seat belts and move around the cabin; however passengers should keep their seat belt fastened when seated. The passenger cabin layout consists of three sections. The 747-400 is unique in having two decks; on the upper deck, behind the flight crew there is the first class section. On the lower deck, at the front, the business class section, for passengers who pay the full fare: while behind is the much larger economy section for passengers who have special cheap rate tickets. The stewards and stewardesses—14 in all—are now busy around the galleys. A choice of drinks, followed by dinner, video entertainment including a film and finally breakfast in the morning is the order of service. Individual headphones are distributed, and these, when plugged in to the arm of the seat—give a variety of in-flight musical programs. Also in the arm of the seat are the controls for a personal reading light, fresh air control and call button. Dinner is served on specially prepared trays, perhaps prawn cocktail, followed by a choice of roast chicken or braised steak with chocolate mousse to finish. The chicken and beef has been heated in the special microwave ovens in the galleys. It is hard to believe that a hot, three-course meal can be served while the plane is flying at this altitude and speed. Dinner over, the cabin lights are dimmed, the blinds by the windows are drawn, the screens unfold and the film begins.
