Introduction
Aviation has increased mobility and made travelling to some of the places where other means of transport would reach an easy task. In conjunction with that, aviation has changed the way people conduct their lifestyles because, due to its speed and ability to navigate almost all places in the world, cultural factors and lifestyles can easily be transported from one place to another. But aviation has not only expanded but also impacted our society in different ways both positively and negatively.
American Aviation History
Though airplanes were fast used by other countries for military purposes, America was the first country that used airplanes for commercial civil and non-military functions which were mostly aero-photography, crop spraying and delivery of mail. America was among the first countries where airplanes were discovered in early 1900’s but the government showed minimal interest, and the industry did not expand as fast as it did in other countries in Europe.
For years therefore, America remained behind technologically as Europe was improving its technology in the aviation industry. Fortunately, America started picking up in early 1930’s and by late 1930’s America’s aviation industry had expanded very much that America was the largest manufacturer and exported the largest number of aircrafts than any other country in the world (Crouch 314).
After World War II America’s aviation industry increased the rate at which it was expanding with the government injecting money for research and development leading to discovery of advanced aircrafts. By late 1980’s America’s technology had tremendously improved making the country the most advanced in the world in terms of aviation technology.
Positive Aspects
Aviation expansion has helped in propelling economic growth in America because of the economic benefits that are associated with it. The number of passengers being transported has been improving from the years following World War II therefore, increasing the demand for air transport thus increasing revenue for airlines.
Aviation has also gone a long way in influencing the expansion of trade by making importation and exportation faster and convenient, hence boosting international trade and this has helped in increasing aggregate income of Americans (Verhovek 141).
The deregulation of the airline industry in 1978 enabled increase in competition and efficiency in the airline industry, leading to reduction of fares and increase in areas covered thus benefiting the stakeholders. In addition to that, aviation industry has led to the discovery of military jets that have put America in a good position to defend itself from enemies.
America has the most advanced and fast military planes which make it afford one of the most well equipped and strong military sector in the world. In conjunction with that, during 1980’s through to 1990’s America produced wide bodied aircrafts which reduced the costs of operation for airlines due to economies of scale and economies of scope (Crouch 531).
Furthermore, discovery of jet engines helped in increasing the speed of air planes and though the initial jet engines were not fuel efficient, advancement in technology led to emergence of piston engines which were more fuel efficient.
Negative Aspects
The increase in aircraft operations has also led to some negative impacts in the American society. To begin with, airplanes release gases from their fuels when they fly thus contributing to global warming and ocean acidification. Carbon dioxide and other nitrogenous gases are released by airplane engines due to fuel combustion as well as from ground airport vehicles, emissions from energy demanding activities in airport buildings and in the manufacturer of aircraft.
Additionally, aviation industry contributes highly to greenhouse gas emissions which contribute to ozone layer depletion. Research conducted in 1997 showed that aviation industry contributed up to 3% of US greenhouse gas emissions from human activities, implying that aviation plays a significant role in depleting the Ozone layer (Wolfe 353).
On the same note, the growth in aviation has brought with it the effect of noise pollution. Aircrafts produce a lot of noise when they are taking off or landing and this highly affects people who are living close to airports. Besides the direct effects of noise pollution, it is also a financial expense since money has to be spent in combating and reducing its effects.
Since the end of the Cold war, the aviation manufacturing has been declining with manufacturers reducing to just about five manufactures from the once high number of 47 (Verhovek 98). Consequently, employment has reduced in the aviation industry by around half during the same period.
On top of that, the quality of plane produced in America has been declining in recent years, and in 2003 the secretary of the air force and the air force chief of staff general warned that their pilots were doing better if they were flying imported airplanes. This has been partly as a result of people viewing aviation negatively and also the lack of enough research. It has also been noted that in recent years the number of students who want to study aviation engineering is declining sharply (Wolfe 254).
Conclusion
Aviation industry has gone through testing times in America to gain the market share and public confidence it enjoys today. On top of that, aviation industry requires constant technological advancement therefore the government should be ready to invest in research and development so as the country may keep up with other countries. Nevertheless, aviation plays an important role in our economies and should therefore be given adequate attention.
