Aging aircraft wiring problems and solutions Essay

Aging aircraft wiring problems and solutions - Essay Example Aging aircraft wiring has been a cause of significant threat to both invaluable human life and material. It is almost certain that a smart wiring alone will not be the solution to this problem considering the working conditions of an aircraft. Keeping this scenario in mind this paper is trying to consider a few of the most pressing safety problems in aviation today. The NTSB (National Transportation Safety Board) later determined the cause of the TWA 800 accident to have been a wiring failure that led to an ignition spark in the fuel tank. The Swissair disaster is believed to have been caused by electrical arcing originating from an in-flight entertainment cable. These disasters provided the initial impetus to begin reshaping commercial wiring policies' (Kevin R. Wheeler and Dogan A. Timucin 2007).A TWA747, flight 800, heading for Paris and Rome with 230 from JFK international airport on the night of July 17, 1996, exploded shortly after take off and during initial climb out. The hug e aircraft was blown up killing all the passengers and crew aboard. One of the most extensive aircraft investigations in the history was initiated following the crash. After many findings the initial fear of a terrorist missile attack was vanished. Enormous efforts were vested on the recovery process along with the FBI and NTSB investigations. The search was supported by FAA, US Navy Boeing and hundreds of contractors. Finally, the remains of the aircraft were recovered from Atlantic. To the continuing frustration of conspiracy theorists, investigators determined that the aircraft was not downed by a bomb or missile, but rather fell victim to a much more insidious enemy - faulty wiring. Hot or chafed wire is believed to have ignited the fuel vapors in the empty center wing tank, creating a massive explosion and in-flight breakup of the aircraft. The similar incidents occurred in the aviation industry at regular intervals. Obviously the wire and connector fault detection and prognosis problem is difficult and each agency is doing the best that it can with the resources given (J.S. Barrett and M.A. Green 1994). Thus, developing the appropriate theoretical approach, using simulations and data collection for development and eventually leading to requirements definition for all aspects of the wiring fault detection problem seem to be a huge task. The terrific crashes remind us that the aircraft electrical system malfunctioning can lead to tragic eventualities in terms of human life and monetary loss. Wiring problems often lead to troubleshooting nightmares, and canceled missions. With miles of wire bundles running through barely accessible compartments, inspecting and repairing wiring problems can eat up your maintenance budget and resources in a very short time. To help maintenance managers address these types of issues, we investigated the tools and techniques that can be used to minimize down time and improve safety. Jim sparks (2004) felt that 'wiring in aircraft has been installed without much thought given to the overall life. The concept has been one of "fit and forget." Various failure modes and their severity may not have been considered during the design or modification process. Maintenance programs often did not address the impact of insulation breakdown and resulting arcing, nor was consideration given to the probability of splices

Income Distribution in the U.S Essay Example | Topics and Well Written Essays - 2250 words

Income Distribution in the U.S - Essay Example It looks at the income that the rich and the poor are getting. It also critically looks at the factors that can lead to income distribution inequalities like taxing, technology and globalization. It helps in explaining various theories like human capital and economic discrimination. For this purpose, it helps an economy to come up with ways to reduce the gap between the rich and the poor. It has been a global concern in fighting poverty. Even though poverty can not be fully eradicated it can be reduced. It is important to look at how factors of production are distributed within an economy. How easy it is for every individual to access these factors is another way to know how well the income is distributed within an economy (Richard, pp.345-450). It is important to look at the income distribution trends in America to find out how the gap between the rich and the poor can be reduced. Very many economists are interested in fighting the gap between the rich and the poor. The gross domestic product (GDP) has been refuted in telling if the citizens of a country are rich or poor. Many economists argue that a country can have a very high gross domestic product but it is only being produced by 10% of the citizens who are the elite and affluent people of the society. The Gini coefficient has been used by the American economists to tell if the country has equal distribution of income. It can simply be said that some professions are well paid but others earn very low wages (Richard, pp.345-450). It is notable that 1948 to 1968, the Gini coefficient reduced. When the Gini coefficient reduces then it means that the citizens’ income per citizen is increasing. Thus between those years the income inequality in America had reduced meaning that families were receiving more income than before. On the contrary, the Gini coefficient increased between 1968 and 1998, this meant that the
