“…With a passenger capacity of 261 seats (see Table 3), the new mid-range aircraft is assumed to be a potential candidate for the 200 to 300 seats market. Similar to the methodology applied in [48], the above mentioned flight schedule data for the respective seat categories are filtered for those routes, which can be operated by a mid-range aircraft designed for a 3900 NM range. Then, flight missions are computed in increments of 100 NM to determine a set of aircraft trajectories with the aircraft state variables, including flight distance, pressure altitude, and fuel and emission flows as a function of time.…”

One of aviation’s major challenges for the upcoming decades is the reduction in its climate impact. As synthetic kerosene and green hydrogen are two promising candidates, their potentials in decreasing the climate impact is investigated for the mid-range segment. Evolutionary advancements for 2040 are applied, first with an conventional and second with an advanced low-NOx and low-soot combustion chamber. Experts and methods from all relevant disciplines are involved, starting from combustion, turbofan engine, overall aircraft design, fleet level, and climate impact assessment, allowing a sophisticated and holistic evaluation. The main takeaway is that both energy carriers have the potential to strongly reduce the fleet level climate impact by more than 75% compared with the reference. Applying a flight-level constraint of 290 and a cruise Mach number of 0.75, causing 5% higher average Direct Operating Costs (DOC), the reduction is even more than 85%. The main levers to achieve this are the advanced combustion chamber, an efficient contrail avoidance strategy, in this case a pure flight-level constraint, and the use of CO2 neutral energy carrier, in a descending priority order. Although vehicle efficiency gains only lead to rather low impact reduction, they are very important to compensate the increased costs of synthetic fuels or green hydrogen.

Civilian aviation continues to contribute significantly to the total economic and environmental impact of aeronautics. Reduction of the fuel burn and environmental impact of civilian aviation is critical to the overall sustainability of the industry, and it can be accomplished, in part, through the optimization of arrival and approach procedures. This paper proposes the development of a method for measuring the degree of compliance of optimized approach trajectories with air traffic management (ATM) intentions, using an intention compliance level (ICL) indicator. Based on fuzzy logic, this measure reflects the extent to which approach trajectories satisfy the required time-of-arrival constraints. This research demonstrates an approach trajectory strategy that maximizes the ICL, maintains compliance with ATM intent, and achieves efficiency goals inclusive of reduced fuel consumption through selective airspeed changes. Simulations on the Airbus A320 indicate that achieving the optimal trajectory and flight parameters can significantly guide trajectory-based operations to minimize airline economic costs and reduce environmental impact while complying with ATM commands. In this paper we will organize the data as follows. The Introduction will summarize past research as a means of identifying the gaps that this research seeks to bridge and introduce the premise of our findings. Section II proposes the concept of ICL to evaluate the relationship between flight time and the required time of arrival and establishes an en-route descent trajectory model. Section III constructs the optimization strategy based on simulated annealing genetic algorithm (SAGA), evaluates the effectiveness of the algorithm, and verifies the contributions of the ICL in a basic scenario. Section IV analyzes the impacts of various factors on the optimization results in a complex scenario.
