    Air transport is a major driver of the nation's economic and social development. This plant covers all operations involving the transport of goods and people by air. Air transport connects people, countries and cultures around the world. In addition, it opens up the market for international players, thus greatly supporting trade and tourism. Air transport has played a significant role in the development of trade, communications, trade and tourism worldwide. Despite the massive expansion, air transport faces serious challenges such as high fuel consumption, fuel prices, air traffic growth, competition, economic crisis, greenhouse gas emissions, safety, design and operational challenges. The fuel consumption is considered to be a major problem facing the air transport industry. Due to high oil prices and increasing competition, fuel consumption is rapidly becoming an important issue in the air transport industry. The rapid growth of the global economy last years also boosted oil demand, which in turn boosted its value. The aviation sector accounts for about 5.8 % of total oil consumption worldwide. Aviation fuel consumption today corresponds to between 2 and 3 % of total fossil fuel use worldwide, more than 80 % of which is used by civil aviation. It is predicted that traffic will grow 5 % per year to 2026 and fuel demand 3 % per year. Fig. 1. shows the rate of fuel consumption since 2005. Fuel consumption is one of the most important measures of direct operating costs in an air traffic control area. Fuel is the main and most volatile of operating costs, managing this issue is a growing challenge for the aviation sector. Airbus estimates that in 2003, fuel was about 28% of the total operating costs of a typical A320 family operator. But in the near future it may be more than 45% of all aircraft operating costs. The country's economy is largely dependent on oil prices. Increased fuel consumption affects airlines in two ways; direct impact on operating costs and reducing air and air travel needs.
