Energy and Environmental Analysis

Reducing Noise, Fuel Burn and Emissions

In the past six decades, fuel efficiency of aircraft has improved by 70 percent per passenger, noise levels have decreased by 75 percent per aircraft and CO2 emissions have fallen by 50 percent. However, with the increased air traffic it is imperative that we continue to seek new solutions that will further reduce aviation’s impact on the environment.

Through energy and environmental analysis, Metron Aviation possesses a comprehensive understanding of the environmental impact of air transportation and is committed to helping the aviation industry address vital environmental and energy-related challenges that will improve the sustainability and harmonization of global aircraft operations. Metron Aviation provides a wide range of environmental services and is involved in several near- and long-term initiatives, including:

  • NextGen Air Transport—Metron Aviation conducts ongoing research into the long-term environmental impact of new developments in the air transportation industry worldwide. In the U.S., the focus is on the effects of  anticipated operational improvements, such as the widespread adoption of arrival profiles using lower thrusts and less fuel, as well as the effects of alternative fuels and improved engine/airframe technology.
  • Decreasing Fuel Consumption through Collaborative Decision Making (CDM)—Metron Aviation has been associated with improvements in efficiency, related to better data sharing and tactical planning of Air Traffic Management (ATM) measures for more than a decade. These measures reduce delays and improve planning during delays by transitioning to engine-off states whenever possible and taking delays on the ground in order to save fuel.
  • Surface/Terminal Traffic Management—Metron Aviation has developed surface management systems that provide better situational awareness and improved planning of surface activities, by coordinating slots in different phases of the traffic management process. These system enhancements reduce fuel consumption and emissions by avoiding delays for aircraft in an engine-on state, minimizing surface queues and taxi times.

Maximizing Environmental Efficiency

Airspace cannot be designed in isolation—the impact of fuel burn, noise and emissions on the surrounding population must be considered as well as the overall impact on the environment.

Metron Aviation has more than 20 years experience in aviation environmental modeling and analysis, which includes direct involvement with FAA, NASA, and Eurocontorl for  NextGen, and SESAR issues. It develops and applies fuel/CO2, air quality, and noise models, and we perform full system-wide analysis of environmental impacts, as well as regional or airport-specific analysis, paying close attention to key drivers of environmental impacts:

  • Engine/airframe technology and insertion into fleet
  • Operational improvements
  • Demand structure and how fleet services demand
