Abstract
With mounting concerns over environmental sustainability, the aviation industry faces pressure to reduce its carbon footprint, not only by redesigning aircraft with advanced technologies and materials but also by exploring new avenues like operations-based optimization. This paper supports these efforts by presenting a comprehensive fleet-level analysis for shortrange single-aisle aircraft entering service around 2035, assessing potential global carbon emission reductions through reduced and optimized cruise speed and design range. Using multiple operational scenarios based on vehicles optimized for different and shorter ranges, the impact of introducing new short-range vehicles into future fleets on fuel burn is compared to the present. Although an aircraft’s fuel consumption decreases with a reduced design range due to a smaller vehicle size and thrust requirement, the reduced design range also limits the number of operations the aircraft can cover. The variants that have the largest impact on global and in-class fuel burn were shown to be the ones sized for a design range closest to covering most or all of the existing missions but without going over. The fleet analysis results provide insights for determining the optimal mission profile for the conceptual design of the next-generation single-aisle aircraft.
