Aviation fuel demand modelling in OECD and developing countries: impacts of fuel efficiency

Abstract

On the quest for reducing the fuel consumption per passenger per flight for economical and environmental reasons, commercial aircraft manufacturers are implementing new strategies for optimising aircraft performance by using new lighter and stronger materials and enhancing engines' efficiencies in terms of fuel consumption and maintenance requirements. With the rising and falling of economies, whether in the Organization for Economic Cooperation and Development (OECD) countries or other developing countries, the aviation industry has been affected by multiple factors such as passenger traffic, freight traffic, airport capacities and oil prices. Aircraft manufacturers have worked on improving the engine efficiency of their newly built airplanes (e.g. Airbus's A-380 and Boeing's B-787), and many airports in the world have increased the number of their runways to face the increasing demand for air traffic in the world. Aviation efficiency can also be achieved through better load management, which in return enables airliners to cope with higher oil prices or rising costs. Aviation fuel demand is modelled in OECD North America, Europe and Pacific regions and some selected developing countries. Price elasticities of fuel demand in all regions are low, while income elasticities are high. The elasticity of aviation fuel demand on passenger kilometre performed (PKP) is considerably low. One per cent increase in PKP leads to less than half a per cent increase in aviation fuel demand, confirming an ongoing fuel efficiency in aviation industry. Copyright 2009 The Authors.

The Impact of Management Practices on Employee Productivity: A Field Experiment with Airline Captains

“…For the latter, there are few credible estimates in the literature due to endogeneity concerns, as airlines can react to changing prices by, for example, altering the number of seats on their aircraft, thereby influencing prices. However, a review of the literature suggests that jet fuel demand is quite price inelastic, with correlational estimates ranging between 0.04 and 0.30 (Mazraati and Alyousif, 2009).…”

“…All these measure were for reducing fuel consumption. Mazraati and Alyousif [50] explained the effect of jet fuel prices, airline ticket prices on the fuel consumption and travel demand. Joosung J. Lee [31] suggested the social pressure and public awareness for fuel burn and emission reduction.…”

A Cost Analysis for Chinese Aviation

“…Mohammad [1] concluded that the importance of the energy and economic markets will continue in the future, and predicted that the US and China markets would grow rapidly. Lee and Fahey [2] found that air traffic had been growing by 5.3% per year on average, based on year 2000 operational data.…”
