“…Several research projects have highlighted the importance of a complete fleet-level analysis in the assessment of new technologies and have proposed advanced modeling frameworks [19][20][21] in which the aircraft flight profiles have to be simulated [22]. Research by Moolchandani et al [23] and Jimenez et al [24] employed fleet-level models to assess the environmental impact of future technologies considered in the ERA project. It was concluded that introduction of ERA technologies can lower the fleettotal fuel burn sufficiently to sustain carbon-neutral operational growth in the future, according to the goals set worldwide, although a discussion of non-CO 2 climate effects is not included.…”

This paper presents a method to assess the key performance indicators of aircraft designed for minimum direct operating costs and aircraft designed for minimum global warming impact. The method comprises a multidisciplinary aircraft optimization algorithm capable of changing wing, engine, and mission design variables while including constraints on flight and field performance. The presented methodology uses traditional class-I methods augmented with dedicated class-II models to increase the sensitivity of the performance indicators to relevant design variables. The global warming impact is measured through the average temperature response caused by several emission species (including carbon dioxide, nitrogen oxides, and contrail formation) over a prolonged period of 100 years. The analysis routines are verified against experimental data or higher-order methods. The design algorithm is subsequently applied to a single-aisle medium-range aircraft, demonstrating that a 57% reduction in average temperature response can be achieved as compared to an aircraft optimized for minimal operating costs. This reduction is realized by flying at 7.6 km and Mach 0.60, and by lowering the engine overall pressure ratio to approximately 37. However, to compensate for the lower productivity, it is estimated that 13% more climate-optimized aircraft have to be operated for the hypothetical fleet under consideration.

“…Reynolds et al (2007) have developed an Aviation Integrated Model (AIM), choosing a policy assessment method able to analyze the relationship between the aviation sector and environmental behavior. Jimenez et al (2012) have suggested a numerically controlled fleet estimation model which dynamically simulates a commercial aircraft fleet based in the USA. Tetzloff and Crossley (2014) proposed to develop route optimization software to define optimal allocations of aircraft movements in the controlled airspace for tracking air safety.…”

The current study aims to analyze the relationships between air transportation and carbon dioxide emissions employing the data from 20 countries in different geographical locations to discover the role of the aviation industry impacts on air quality. The analysis was performed by considering random effect (RE), fixed effect (FE) and ordinary least square (OLS) methods using panel data covering years from 1990–2014, to examine the effect of passenger and cargo transportation on environmental quality. Findings reveal that air transportation has a significantly positive effect on environmental degradation due to a rise in the consumption of fossil fuels, which contributes to an increase in the volume of carbon emissions. The result suggests focusing on new generation aircraft concepts and technologies under fuel strategy scenarios proposed by International Civil Aviation Organization (ICAO) and International Air Transport Association (IATA). Entry to service new generation aircrafts enable use of biofuel with reduced fuel flow which is feasible in order to mitigate CO2 emission level. JEL classification: E10; L93; Q51.

“…EDS has also been used as the simulation environment to perform assessments of different technology portfolios, enabling stakeholders to quantify potential impacts and show their benefits at the vehicle and fleet level [33]. Jimenez [34], for example, employed EDS for the development of vehicle performance models that were later used in fleet-level assessments to estimate the impact of introducing new aircraft systems, featuring new technologies, would have on an entire airline concept of operations. Busch [35] used EDS to perform uncertainty analyses on a notional HWB concept representative of NASA's N3-X electric aircraft.…”
