Parameter

3.3.4.1 taxi services

Taxi services refer to the ground movement of aircraft between airport gates and runways, which can be decarbonized by utilizing electric tugs or landing gear wheel motors. Shifting to low-emission taxiing significantly reduces ground fuel burn, engine wear, and local air pollution. Challenges in implementing these services include managing the high electrical grid loads required to charge airport tug fleets and integrating non-intrusive ground control protocols.
