In the postwar period the passengers and cargo air traffic worldwide has grown rapidly. The plane has stopped for a long time to be a luxury or a prohibitive mean of transportation, being preferred for the rapidity of transport, the smooth organization and running of traffic, increased comfort and safety. The plane remains today the most effective and most used means of transport over long and very long distances. Effective only if we think about speed, because if we think in terms of ecological issues, air transport is a very important source of pollution contributing to ozone depletion and global warming.
On average, every five years a new generation of aircrafts has emerged with a double transport capacity than the one of the previous generation. Today, a Boeing 747 aircraft type can carry 490 passengers and 115 tons of cargo. For cargo, there are used both mixed planes but also specialized aircrafts dedicated for specific types of goods.
In the last decade, the main trend is represented by the use of specialized planes, which generated important changes in the technologies embedded in the aircrafts. Achievements in creating new materials, lighter and more durable, the introduction of improved production processes and the technology of electronic computing have enabled a strong development of the world’s aircraft fleets. All these technological achievements have enabled not just the increase of the transport capacity, but also of the flight autonomy and speed.
Nowadays, after all these developments, there is an increased need to transform the aircrafts into green machines.
High consumption of fuel during flight, and the type of fuel used (fossil fuel) are the main culprits of pollution "in the sky". But even in this field,...

In today’s world, the use of airplanes in wars or in everyday life has become a part of how we live as human beings. Removing the air forces of the world is like taking a step back in time when wars were only fought on land or sea. WWI began only eleven short years after the Wright brothers achieved powered flight in 19031 and yet aircrafts were being used for surveillance and eventually combat purposes. It is understood that these aircrafts were primitive, but they laid down the foundation for what we know today as fighter jets. The Fokker Eindecker “revolutionized air combat by successfully employing a synchronized forward -firing machine gun mounted on the engine cowling”2. Because this airplane became the first to successfully use a synchronized machine gun, it allowed its pilots to become the first aerial combat tactitions3.
Planes have developed immensely through the years. The Wright brothers developed the first plane in 1903.
In this paper, I would like to discuss on the video, “21st century jet.” This video is about the launching and testing of the airplane by the Boeing company, 777.The 777 family is designed to fill the size gap between the 767 and 747.The head of the 777 project is Allen Millaley, who promised to do many things which are impossible, produced the plane which is more reliable than any other plane in the aviation history. The first large passenger jet designed completely by computer, the 777 is more complex and innovative than any other airliner ever built.

One of the major facets of tourism is transportation. The ability for people and equipment to be able to move from one place to another smoothly is not only a convenience but a necessity. Air transportation is one of the largest and fastest growing industries associated with tourism. From passenger travel to food and supply transport there are seemingly ever increasing numbers of flights occurring to help meet the demand. With the increase in flights, comes the increase of pollutants into the air, water, and soil. These emissions, as well as those from the electricity production are linked to acid rain, chemical pollution and global warming. These pollutants have effects not only in populated cities, but also in isolated natural environments as well. S...

The Boeing 737 is one of the most popular aircraft ever produced. Over 7700 in all variants have been produced, with an additional 11,275 aircraft on order. This makes the 737 the most popular jetliner to date. The 737 has a wide variety of uses, and still remains extremely popular and under high demand. Because it is such a widely mass produced aircraft, it is also a target for constant aerodynamic improvements. Boeing has looked at everything from the design of the anti-collision lights, to the reduction of small gaps in the airfoil. This has created an aircraft that is extremely aerodynamic and efficient at any task it performs.
Throughout history, the concept of sustainability has not been prevalent in the lives of common people. Changes weren 't able to be observed and measured so there was no immediate concern about the topic. With technology and the increasingly demanding pace of living, being sustainable is more important now than ever before. Sustainability is defined as meeting the needs of the present without compromising the ability of the future. Sustainability is made up of many facets that can be overwhelming if learned at once. Focusing on one aspect of sustainability and necessary steps needed to fully achieve it is a very effective method of applying sustainability. In the world today, a growing concern has been the carbon footprint created by aviation.
The main opportunities that the scheduled air transportation will have in the next five years are the possible decrease of TSA agents at airports, technology increasing the safety and comfort of the flights for the passengers and ...
Aviation has a huge environmental impact to the environment and society, the aircraft engines releases a noise that affects human life and the particulates and gases that are released from the aircraft engines contribute to climate change and increases the global warming. Despite the emission reductions from cars and more fuel-efficient and less polluting turbofan and turboprop engines, the rapid growth of air transportation in the recent years contributes to an increase in total pollution attributable to aviation. In the European Union, and increased greenhouse gas emissions from aviation increased by 87% between 1990 and 2006. Like any other form of public mass transportation that relies on resources that are extracted from the planet for e.g. Oil, and the airline cannot be considered sustainable in the long-term too. Because of the limited resources in which the Aviation relies on, it is more realistic to think how to improve the sustainability of the air transportation rather than achieving a sustainable development. Demand for air transport is growing constantly and, if this demand is to be met with all the benefits associated, the community or society must also accept the costs like; (Pollution, Aircraft noise, Environment change, risk, and resources consumption, etc.).
Aviation industry deals with more than thousands of people and also spending millions of funds in order to meet the requirements, satisfy the necessities of people and to produce state-of-the-art aircraft. With its objective it is significant to consider the hazards involved and bring out an output with the least extent and under control risks to prevent any loss in terms of life and even profit.
Air travel has grown in the past decade. Travel grew strongly for both leisure and business purposes. India will have nearly 800 to 1000 airplanes by 2023, it was estimated by Airbus. In spite of growth between 30 to 50 per cent in Indian aviation industry, losses of approximately 2200 crore is estimated for the current year.
The future of passenger aircraft and their manufactures has an amazing outlook. Every year the brightest minds in aviation compile the greatest technological advances towards creating the safest and most economical aircraft on the planet. No detail is over looked, and the bottom dollar is the all controlling factor. From private aircraft to public aircraft, space exploration and beyond, the future is bright for the passenger aircraft market, and everyone who purchases air travel should be excited to see how industry unfolds.
Factories and transportation depend on huge amounts of fuel--billions of tons of coal and oil are consumed around the world every year. When these fuels burn they introduce smoke and other, less visible, by-products into the atmosphere.
