Cost benefit and environmental impact assessment of autonomous eTaxi

One of the proposed methods of decreasing fuel consumption and emissions at airport is by equipping aircraft with electric motors for movement on the ground. In this paper a high level determination is given on what the potential average and marginal fuel savings and impact on emissions is for some of the larger airports and airlines in Europe and North America. The system could potentially be deployed on a selected sub fleet of aircraft, but fleet wide integration is not likely to result in cost covering benefits. The system is shown to be most beneficial on shorter flights between large airports, provided aircraft are not towed there.
