A Fuel-Payload Ratio Based Flight-Segmentation Benchmark

Airlines and their customers have an interest in determining fuel- and emissions-minimizing flight segmentation. Starting from Kuchemann's Weight Model and the Breguet Range Equation for cruise-fuel consumption, we build an idealized model of optimal …

Rank-order concordance among conflicting emissions estimates for informing flight choice

Air transport Greenhouse Gas (GHG) emissions estimates differ greatly, depending on the calculation method employed. Among the IPCC, ICAO, DEFRA, and BrighterPlanet calculation methods, the largest estimate may be up to 4.5 times larger than the …
