Fuel serves as the single largest cost for a majority of aircraft operators. In fact, some experts estimate that every pound of an aircraft’s weight, including crew, passengers, baggage, and the aircraft itself, contribute to about $10,000 in annual fuel costs. To reduce aircraft weight and fuel usage, aerospace engineers, aircraft designers, and maintenance organizations are reevaluating 21st century airplanes. In this blog, we will outline four ways changes in aircraft design can help reduce fuel costs and consumption.
