Abstract This paper examines technological disasters in the airline industry. In particular it looks at the British jet aircraft industry after the accidents. It allows us to gain insight into what people's conceptions were, and why certain events unfolded as they did. It shows us how people can learn from technological disasters, and even though they seem catastrophic at the time, they give us the necessary tools to insure that such disasters do not happen again.
From the paper:
"The Comet planes, operated predominantly by BOAC had established Britain as both a successful pioneer and leader in civil jet aviation. However, several American companies, including Boeing, were in hot pursuit of de-Havilland, fighting for their share of the new civil jet market. ?The Comets symbolized to Britons their nation's pre-eminence in jet aviation,? 5 and so the accidents came as a devastating blow, both in the short and long term. In the aftermath of the accidents, all Comets were grounded pending investigation, causing huge problems and losses."
Abstract An analysis of how weapons have developed in the 20th century and the affect that they have had on the many wars fought in this century. It gives examples of different types of explosives, firearms, tanks, aeroplanes, submarines etc and explains how each of these has changed the character of war and battles.
From the Paper "Wars have always varied from one era to another, and one major reason for that variance is the weaponry of that time. Strategies and weapons revolve around the technology of the time. In the Twentieth Century there were many new weapons invented, which significantly changed the ways wars that were fought. These weapons range from handheld grenades, to nuclear warheads. They also include new transportation modes such as submarines or airplanes. Each weapon affected wars, some more profoundly than others. "
Abstract This paper describes how this system allows aircrafts to communicate and report to the ground and vice versa. It explains the processes involved, the transmitting of data on VHF frequencies that can be received and decoded. It is a digital data system in VHF (Aviation). It makes it possible for aviation companies to "communicate" and track the planes of their fleet.
From the Paper "The Aeronautical Radio, Inc. (ARINC) maintains a huge worldwide VHF and HF voice network to provide operational radio communications for the aircraft industry. ACAR was designed and developed in the early eighties. It was produced to reduce the flight crew's workload by using modern computer technology to exchange many routine reports and messages. ACARS uses the AM mode because the same airborne VHF radio is often also used for voice communications. Burst transmissions are used with a limit of 220 characters per message. Transmissions often last less than one second."
Abstract A discussion about a career as an aircraft mechanic. The writer uses five sources to explore the education and skills that are required for the career. It examines the changing airline industry and evolving occupation of aircraft mechanics. Includes details of what the profession entails and what skills are appropriate as well as the positive future outlook for those who choose to work in the field.
From the Paper "The airline industry is an ever-changing field. There are many types of aircraft being used today, including, freight, commercial passenger and private passenger planes. Each plane has to be built, maintained and fixed when something goes wrong. The field of airplane mechanics is a growing and always changing area of job exploration. Skills as an aircraft mechanic can be utilized in the armed services, the commercial airline field, or at an airfield with private aircraft. They can also be used to work where airplanes are sold and brought in for maintenance and repair. It is a field that promises to continue expanding and as the world continues to globalize the opportunities will continue to increase."
Abstract This paper explains that, while many people contributed to the birth of aviation in America, most of them are known to the public. Henry Ford also made a significant contribution, and the paper pays tribute to this. The writer shows how Ford laid many of the building blocks required for commercial aviation as we know them today: communication links, runways, airports, and finally, the all-metal aircraft with the Ford Tri-motor. The Ford Tri-motor became one of the world's first successful passenger airliners.
From the Paper "The Ford Tri-motor planes were produced during the 1920's and the 1930?s. At that time, they were for a wide variety purposes. William B. Stout, an engineer and also a very bold and daring salesman scouted and reviewed designs for aircraft engines. He, however, required funding and approached many of the leading businessmen like Ford and Edsel. He managed to collect $20,000 to start the aircraft project. The Stout Metal Airplane Company developed the first Tri-motor airplane in the early 1925. The first model was known as the 2-AT Pullman and was a single engine plane. Ford acquired the Stout Metal Airplane Company in August 1925 and subsequently designed the 3-AT, which was not a successful plane."
Abstract This paper firstly discusses the most important component that fails in a reciprocating engine, the human component. It investigates an accident of a big aircraft, Lockheed Super Constellation, in order to qualify this opinion. The paper then examines the Cessna as an example of engine problems as a cause of aircraft accidents. The author stresses that it is the pilot error that causes 95 percent of the accidents for reciprocating engine aircraft.

From the Paper "Now let us look at the causes of accidents from an engine point of view. Both turbine engines and reciprocating engines process air in the same manner and that means that they both have intake, compression, combustion and exhaust. In the reciprocating engine one step has to follow the other and in the turbine engine all the processes proceed all at the same time and without any interruption. The other difference is that in the turbine engine there are separate components decided for the particular operation of the cycle, while in the reciprocating engine, all the functions take place in the same combustion chamber. The design of each engine gives certain benefits and advantages, and when the issue is considered from thermal efficiency, reciprocating engines are easily more efficient. They have a complex design, but the engine has had a longer period to be developed and perfected. The general view is that turbine engines have simplicity of motion and this has given a reputation for being more reliable, though it burns more fuel than a reciprocating engine."
Abstract This paper takes a brief look at what characterizes American Airlines and the tactics they will have to employ if they hope to survive their current economic situation. This paper also takes a look at the reluctance of Americans to fly as a result of 9/11 and other terror attacks.
From the Paper "The airline industry is characterized by very complex pricing dynamics, depending on travel distance, type of traveler, and domestic and international flights, to name a few of the many factors that determine the degree of price elasticity or inelasticity (Air travel demand elasticities: Concepts, issues and measurement). For long-haul international business travel, demand is not sensitive to fare changes because there are few close substitutes. On the other hand, long-haul domestic business travelers have much higher elasticities than international business travelers. Telecommunications has become more acceptable as a substitute in domestic markets due to common culture, laws, contracts, etc. Likewise, international leisure travelers have greater elasticity than do international business travelers. These consumers are more likely to either postpone their trips in response to higher fares or seek locations that are not as expensive. "
